CalDAV Class

Properties   Methods   Events   Config Settings   Errors  

The CalDAV Class implements an easy-to-use interface to the Calendaring Extensions to the Web Distributed Authoring and Versioning protocol (WebDAV). In this manner the CalDAV protocol specifies a standard way of accessing, managing, and sharing calendaring and scheduling information based on the iCalendar format.

Remarks

The CalDAV Class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

The class allows remote management of calendar events and collections of events (the calendar itself), including creation, deletion, listing, copying, and moving. Resource locking is also supported.

The GetCalendarReport method will list the event resources contained in the calendar, and the ReportFilter can be used to limit the results returned. The EventDetails event will be fired for each matching calendar resource. You may also request a report containing a list of times that the owner is free or busy using the GetFreeBusyReport. The FreeBusy event will fire for each entry received, and the data fired in the event will also be stored in the FreeBusy property.

Single events can be added to a calendar (or updated) using the PutCalendarEvent method, and can be retrieved via the GetCalendarEvent method. Events may be copied or moved with the CopyCalendarEvent and MoveCalendarEvent.

Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.

Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return a HTTP 403 Forbidden response.

The following properties are used when creating a request with PutCalendarEvent or ExportICS, and will be filled after calling GetCalendarEvent or ImportICS. These will also be available from inside the EventDetails event, which is fired for each event received from the CalDAV server in response to a GetCalendarReport.

• Alarms
• Attendees
• Categories
• Classification
• Completed
• Created
• CustomProperties
• Depth
• Description
• DisplayName
• Duration
• EndDate
• EventType
• LastModified
• Location
• Organizer
• Priority
• Recurrence
• Sequence
• StartDate
• Status
• Summary
• Timestamp
• Timezone
• Transparency
• UID
• URL

Each method that acts on the calendar takes a ResourceURI parameter, which points to either an event resource or to the calendar itself. Event resources have a URI that ends with a filename and the ".ics" extension. Calendar resources end in a directory path. The following methods all act on events, and thus their ResourceURI parameters must terminate in a filename with the ".ics" extension:

• CopyCalendarEvent
• DeleteCalendarEvent
• MoveCalendarEvent
• GetCalendarEvent
• PutCalendarEvent

• CreateCalendar
• GetCalendarOptions
• GetCalendarReport
• GetFreeBusyReport

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

Data Type

String

Authorization Property (IPWorks_CalDAV Class)

This property includes the Authorization string to be sent to the server.

Object Oriented Interface

public function getAuthorization();


public function setAuthorization($value);

Procedural Interface

ipworks_caldav_get($res, 12 );


ipworks_caldav_set($res, 12, $value );

Default Value

''

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

Data Type

String

AuthScheme Property (IPWorks_CalDAV Class)

The authentication scheme to use when server authentication is required.

ipworks_caldav_set($res, 13, $value );

Default Value

0

Remarks

This property will tell the class which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the class will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the class.

For security, changing the value of this property will cause the class to clear the values of User, Password, and Authorization.

Data Type

Integer

Categories Property (IPWorks_CalDAV Class)

Within the "VEVENT", "VTODO", or "VJOURNAL" calendar components, more than one category can be specified as a COMMA-separated list of categories. For example: CalDAV.CalendarEvents[0].Category = "APPOINTMENT,EDUCATION,MEETING";

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

ETag Property (IPWorks_CalDAV Class)

Identifier returned by the CalDAV server which is used to synchronize edits.

Object Oriented Interface

public function getETag();


public function setETag($value);

Procedural Interface

ipworks_caldav_get($res, 36 );


ipworks_caldav_set($res, 36, $value );

Default Value

''

Remarks

This property identifies the state of the event in the calendar. An ETag is returned by the CalDAV server after a successful PutCalendarEvent request. Every time an event is updated, the ETag changes. This gives you the ability to determine if another user has changed the event you added.

You can use this ETag value to maintain a cache. If you submit a GetCalendarReport request with the ReportFilterReturnCalendarData property set to False only the URI and ETags for each event in the calendar will be returned in the report. You can cache the ETag and URI locally, and then inspect the report for any changes and update only the events that have changed ETags.

When updating an event with the PutCalendarEvent method, you may add the ETag to the "If-Match" header (using OtherHeaders) in order to insure that you are not overwriting more recent changes on the server. For instance: calDAV.UID = "20110202T000000Z-6414-500-10112-204@nsoftest"; calDAV.StartDate = "20110202T000000Z"; calDAV.EndDate = "20110202T110000Z"; calDAV.TimeStamp = "20100301T000000Z"; calDAV.Summary = "Dinner with friends"; calDAV.Description = "Getting everyone together for some food and fun"; calDAV.Location = "The James Joyce Irish Pub"; calDAV.EventType = CaldavsEventTypes.vEvent; calDAV.OtherHeaders = "If-Match: 1900-1900\r\ n"; calDAV.PutCalendarEvent "https://caldav.calendar.yahoo.com/dav/user_name/Calendar/My_Calendar/20110202T000000Z-6414-500-10112-204@nsoftest.ics" If the current ETag for the above event is "1900-1900", then the above modification will work perfectly. However, if the event was modified on the Yahoo server, the ETag will not match and the above will fail with an HTTP Protocol error: "409 Conflict". In that case you should retrieve the event with GetCalendarEvent and update the most recent version.

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

FollowRedirects Property (IPWorks_CalDAV Class)

This property determines what happens when the server issues a redirect.

Object Oriented Interface

public function getFollowRedirects();


public function setFollowRedirects($value);

Procedural Interface

ipworks_caldav_get($res, 44 );


ipworks_caldav_set($res, 44, $value );

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the class fails with an error instead.

Data Type

Procedural Interface

ipworks_caldav_get($res, 52 );


ipworks_caldav_set($res, 52, $value );

Default Value

'write'

Remarks

The type of the current resource lock.

Before the calendar resource can be locked, the LockType may be set to the type of lock being requested. Currently, the class only supports requesting locks of type "write", although the protocol defines an optional "read" lock. After a successful LockCalendar operation, the class will set the LockType property to the correct value returned in the server's response.

Procedural Interface

ipworks_caldav_get($res, 55 );


ipworks_caldav_set($res, 55, $value );

Default Value

0

Remarks

The time to live for the current resource lock.

Before the calendar resource can be locked, the Lock LockTimeout may be set to a specific amount of time needed for the locked operation to take place. The timeout is used to determine how long the lock may exist before the server automatically unlocks the resource URI. If LockTimeout of 0 is specified, the server will use a default timeout. After a successful LockCalendar operation, the class will set the Lock LockTimeout property to the correct value returned in the server's response.

Data Type

Integer

LockTokens Property (IPWorks_CalDAV Class)

The lock string to be used when submitting operations on a locked resource.

''

Remarks

The lock string to be used when submitting operations on a locked resource.

Before the calendar resource can be locked, the Lock LockTokens may be set to the tokens returned by a previous lock operation. This is useful when renewing a timeout. The server will respond with a new timeout value, which will be stored in LockTimeout. If the lock request is not a lock refresh, LockTokens must be empty, and will be parsed out of the server response after a successful LockCalendar operation.

Data Type

String

Organizer Property (IPWorks_CalDAV Class)

Defines the organizer of a calendar event.

Object Oriented Interface

public function getOrganizer();


public function setOrganizer($value);

Procedural Interface

ipworks_caldav_get($res, 57 );


ipworks_caldav_set($res, 57, $value );

Default Value

''

Remarks

This property is specified within the vEvent, vTodo, and vJournal calendar EventTypes to specify the organizer of a group-scheduled calendar entity. The property is specified within the vFreeBusy EventType to identify the calendar user requesting the free or busy time. When publishing a vFreeBusy EventType, the property is used to specify the calendar that the published busy time came from.

Each email address should be in the mailto URI format (as defined in RFC2368).

For instance: CalDAV.Organizer = "mailto:jane_doe@example.com";

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

ipworks_caldav_set($res, 58, $value );

Default Value

''

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like ContentType and From.

The headers must follow the format Header: Value as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the class beyond what is provided.

For CalDAV, the "If-Match" header is extremely useful. After adding a an event with PutCalendarEvent or retrieving an event with GetCalendarEvent, the ETag property will contain a value indicating the current state of the event. If you wish to update the event, you may pass this returned ETag in an "If-Match" header. If the event on the server has been modified since you retrieved it (and the ETag on the server has changed), then the PutCalendarEvent will fail with an HTTP Protocol Error: "409 Conflict", which indicates there is a conflict between the version you're trying to update and the current version on the sever. For instance: calDAV.OtherHeaders = "If-Match: 1900-1900\r\ n";

This property is not available at design time.

If AuthScheme is set to HTTP Digest Authentication, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

If AuthScheme is set to NTLM, NTLM authentication will be attempted. If AuthScheme is set to NTLM and User and Password are empty, the class will attempt to authenticate using the current user's credentials.

Data Type

String

Priority Property (IPWorks_CalDAV Class)

Defines the relative priority for a calendar event.

Object Oriented Interface

public function getPriority();


public function setPriority($value);

Procedural Interface

ipworks_caldav_get($res, 63 );


ipworks_caldav_set($res, 63, $value );

Default Value

0

Remarks

This property defines the relative priority of a calendar event. The priority is specified as an integer in the range 0 to 9. A value of 0 specifies an undefined Priority. A value of 1 is the highest Priority. A value of 2 is the second highest Priority. Subsequent numbers specify a decreasing ordinal Priority. A value of 9 is the lowest Priority.

A Calendar User-Agent (CUA) with a three-level Priority scheme of "HIGH", "MEDIUM", and "LOW" is mapped into this property such that a property value in the range of 1 to 4 specifies "HIGH" Priority. A value of 5 is the normal or "MEDIUM" Priority. A value in the range of 6 to 9 is "LOW" Priority.

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

Default Value

0

Remarks

This property is used to tell the class which type of authorization to perform when connecting to the proxy. This is used only when the ProxyUser and ProxyPassword properties are set.

ProxyAuthScheme should be set to authNone (3) when no authentication is expected.

By default, ProxyAuthScheme is authBasic (0), and if the ProxyUser and ProxyPassword properties are set, the component will attempt basic authentication.

If ProxyAuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If ProxyAuthScheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If ProxyAuthScheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of ProxyUser and ProxyPassword.

This property is used if you wish to denote specific, individual dates on which the event recurs. If you have an event that occurs monthly or weekly or on some other time interval, use the RecurrenceRule property instead.

This property is filled after retrieving a calendar event, and is also used to create an event to put on the server. However, when requesting a report the contents of this property will only be valid inside the CalDAV EventDetails event.

Data Type

String

RecurrenceExceptionDates Property (IPWorks_CalDAV Class)

Defines the list of DATE-TIME exceptions to the recurrence set.

Object Oriented Interface

public function getRecurrenceExceptionDates();


public function setRecurrenceExceptionDates($value);

Procedural Interface

ipworks_caldav_get($res, 72 );


ipworks_caldav_set($res, 72, $value );

Default Value

''

Remarks

Defines the list of DATE-TIME exceptions to the recurrence set.

If the RecurrenceExceptionDates and RecurrenceExceptionRule are specified, they are used in computing the recurrence set. The recurrence set is the complete set of recurrence instances for a calendar component. The recurrence set is generated by considering the initial StartDate property along with the RecurrenceRule, RecurrenceDates, RecurrenceExceptionRule, and RecurrenceExceptionDates properties contained within the recurring event. The StartDate property defines the first instance in the recurrence set. The starting date SHOULD match the pattern of the recurrence rule, if specified. The recurrence set generated with a start date that doesn't match the pattern of the rule is undefined. The final recurrence set is generated by gathering all of the start DATE-TIME values generated by any of the specified RecurrenceRule and RecurrenceDates properties, and then excluding any start DATE-TIME values specified by the RecurrenceExceptionRule or RecurrenceExceptionDates properties. This implies that DATE-TIME values specified by the RecurrenceExceptionRule and RecurrenceExceptionDates properties take precedence over those specified by inclusion properties (i.e., RecurrenceDates and RecurrenceRule). When duplicate instances are generated by the recurrence RecurrenceRule and RecurrenceDates properties, only one recurrence is considered. Duplicate instances are ignored.

The date/time format is "YYYYMMDDThhmmss", where "T" indicates the break between date and time. You may also append a 1-character alpha code for the timezone. For instance, "20100104T123456Z" indicates January 4th, 2010 at 12:34:56 PM UTC.

This property is filled after retrieving a calendar event, and is also used to create an event to put on the server. However, when requesting a report the contents of this property will only be valid inside the CalDAV EventDetails event.

Data Type

String

RecurrenceExceptionRule Property (IPWorks_CalDAV Class)

Defines a rule or repeating pattern for an exception to the recurrence set.

Object Oriented Interface

public function getRecurrenceExceptionRule();


public function setRecurrenceExceptionRule($value);

Procedural Interface

ipworks_caldav_get($res, 73 );


ipworks_caldav_set($res, 73, $value );

Default Value

''

Remarks

Defines a rule or repeating pattern for an exception to the recurrence set.

If the RecurrenceExceptionDates and RecurrenceExceptionRule are specified, they are used in computing the recurrence set. The recurrence set is the complete set of recurrence instances for a calendar component. The recurrence set is generated by considering the initial StartDate property along with the RecurrenceRule, RecurrenceDates, RecurrenceExceptionRule, and RecurrenceExceptionDates properties contained within the recurring event. The StartDate property defines the first instance in the recurrence set. The starting date SHOULD match the pattern of the recurrence rule, if specified.

This implies that DATE-TIME values specified by the RecurrenceExceptionRule and RecurrenceExceptionDates properties take precedence over those specified by inclusion properties (i.e., RecurrenceDates and RecurrenceRule). When duplicate instances are generated by the recurrence RecurrenceRule and RecurrenceDates properties, only one recurrence is considered. Duplicate instances are ignored.

This value type is a structured value consisting of a list of one or more recurrence grammar parts. Each rule part is defined by a NAME=VALUE pair. The rule parts are separated from each other by the SEMICOLON character. The rule parts are not ordered in any particular sequence. Individual rule parts MUST only be specified once.

The table below shows the supported rules and their usage.

Information not contained in the RecurrenceRule necessary to determine the various recurrence instance start time and dates are derived from the StartDate property. For example, "FREQ=YEARLY;BYMONTH=1" doesn't specify a specific day within the month or a time. This information would be the same as what is specified for the StartDate property.

BYxxx rule parts modify the recurrence in some manner. BYxxx rule parts for a period of time that is the same or greater than the frequency generally reduce or limit the number of occurrences of the recurrence generated. For example, "FREQ=DAILY;BYMONTH=1" reduces the number of recurrence instances from all days (if BYMONTH rule part is not present) to all days in January. BYxxx rule parts for a period of time less than the frequency generally increase or expand the number of occurrences of the recurrence. For example, "FREQ=YEARLY;BYMONTH=1,2" increases the number of days within the yearly recurrence set from 1 (if BYMONTH rule part is not present) to 2.

If multiple BYxxx rule parts are specified, then after evaluating the specified FREQ and INTERVAL rule parts, the BYxxx rule parts are applied to the current set of evaluated occurrences in the following order: BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY, BYDAY, BYHOUR, BYMINUTE, BYSECOND and BYSETPOS; then COUNT and UNTIL are evaluated.

This property is filled after retrieving a calendar event, and is also used to create an event to put on the server. However, when requesting a report the contents of this property will only be valid inside the CalDAV EventDetails event.

ReportFilterEventType Property (IPWorks_CalDAV Class)

Indicates the type of calendar object resources to return in a Report.

Object Oriented Interface

public function getReportFilterEventType();


public function setReportFilterEventType($value);

Procedural Interface

ipworks_caldav_get($res, 80 );


ipworks_caldav_set($res, 80, $value );

Default Value

0

Remarks

Indicates the type of calendar object resources to return in a Report. Some calendar servers (Google in particular) do not support vtAll, so you must submit a report for each type of event you wish to retrieve a report on.

Data Type

Procedural Interface

ipworks_caldav_get($res, 84 );


ipworks_caldav_set($res, 84, $value );

Default Value

true

Remarks

Controls whether the contents of each calendar event is returned in the report.

If ReportFilterReturnCalendarData is True (default), a report will contain the full contents of each event in the calendar. This can be a substantially large amount of data. However if ReportFilterReturnCalendarData is False, the report returned will contain only URIs and ETags of each calendar event. You may compare the URIs against a cached list and retrieve any new URIs individually via the CalDAV.GetCalendarEvent method. If the ETag for a cached URI has changed, it means that the calendar event has changed, and needs to be retrieved.

Note that this filter is not compatible with the ReportFilterRecurStart and ReportFilterRecurEnd properties.

Sequence Property (IPWorks_CalDAV Class)

Defines the revision sequence number of the event within a sequence of revisions.

Object Oriented Interface

public function getSequence();


public function setSequence($value);

Procedural Interface

ipworks_caldav_get($res, 87 );


ipworks_caldav_set($res, 87, $value );

Default Value

0

Remarks

This property defines the revision sequence number of the event within a sequence of revisions. When a calendar component is created its Sequence number is 0. It is incremented by the Organizer's Calendar User Agent (CUA) each time the Organizer makes a significant revision to the calendar event. Therefore, a Sequence number of 2 means the event has been revised twice.

The Organizer includes this property in a calendar event that it sends to an Attendees to specify the current version of the event. Likewise, the Attendees includes this property in an event that it sends to the Organizer to specify the version of the calendar component to which the Attendees is referring.

Note: Recurrence instances of a recurring event may have different sequence numbers.

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

ipworks_caldav_set($res, 192, $value );

Default Value

''

Remarks

This property defines whether or not an event is transparent to busy time searches. Time Transparency is the characteristic of an event that determines whether it appears to consume time on a calendar. Events that consume actual time for the individual or resource associated with the calendar SHOULD be recorded as "OPAQUE", allowing them to be detected by free/busy time searches. Other events, which do not take up the individual's (or resource's) time SHOULD be recorded as "TRANSPARENT", making them invisible to free/ busy time searches.

Custom transparency values may or may not be supported by your calendar implementation, but all implementations will support the "OPAQUE" and "TRANSPARENT" values.

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

Data Type

String

UID Property (IPWorks_CalDAV Class)

A persistent, globally unique identifier for the calendar event.

Object Oriented Interface

public function getUID();


public function setUID($value);

Procedural Interface

ipworks_caldav_get($res, 193 );


ipworks_caldav_set($res, 193, $value );

Default Value

''

Remarks

This property contains a persistent, globally unique identifier. The generator of the identifier MUST guarantee that the identifier is unique. There are several algorithms that can be used to accomplish this. A good method to assure uniqueness is to put the domain name or a domain literal IP address of the host on which the identifier was created on the right-hand side of an "@", and on the left-hand side, put a combination of the current calendar date and time of day (i.e., formatted in as a date/time value) along with some other currently unique (perhaps sequential) identifier available on the system (for example, a process id number). Using a date/time value on the left-hand side and a domain name or domain literal on the right-hand side makes it possible to guarantee uniqueness since no two hosts should be using the same domain name or IP address at the same time. Though other algorithms will work, it is recommended that the right-hand side contain some domain identifier (either of the host itself or otherwise) such that the generator of the message identifier can guarantee the uniqueness of the left-hand side within the scope of that domain.

NOTE: Some CalDAV servers (Yahoo for example) require that the UID and the filename portion of the Resource URI match. For example, if the UID is "hello_world" then the ResourceURI parameter of the PutCalendarEvent should be "https://caldav.calendar.yahoo.com/dav/user_name/Calendar/My_Calendar/hello_world.ics". If the UID and filename portion of the URI do not match, the Yahoo CalDAV server will return a "302 Found" response indicating that the requested resource resides under a different URI. (Meaning the event was not added to the calendar)

This property is filled from the response to a GetCalendarEvent, and is also used when creating an event to be added using the PutCalendarEvent method. However, when requesting a report using the GetCalendarReport method, the contents of this property will only be valid inside the EventDetails event.

Data Type

String

URL Property (IPWorks_CalDAV Class)

Location of the event resource on the CalDAV server.

Object Oriented Interface

public function getURL();

Procedural Interface

ipworks_caldav_get($res, 194 );

Default Value

''

Remarks

This property is read-only, and will be filled with the location of the event resource for each event returned. This will only be returned in response to a GetCalendarReport transaction.

Remarks

This property contains a user name if authentication is to be used. If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

If AuthScheme is set to HTTP Digest Authentication, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

If AuthScheme is set to NTLM, NTLM authentication will be attempted. If AuthScheme is set to NTLM, and User and Password are empty, the class will attempt to authenticate using the current user's credentials.

Data Type

String

AddCookie Method (IPWorks_CalDAV Class)

This method adds a cookie and the corresponding value to the outgoing request headers.

Object Oriented Interface

public function doAddCookie($cookiename, $cookievalue);

Procedural Interface

ipworks_caldav_do_addcookie($res, $cookiename, $cookievalue);

Remarks

This property adds a cookie and the corresponding value to the outgoing request headers. Please refer to the Cookies property for more information on cookies and how they are managed.

AddCustomProperty Method (IPWorks_CalDAV Class)

Adds a form variable and the corresponding value.

Object Oriented Interface

public function doAddCustomProperty($varname, $varvalue);

Procedural Interface

ipworks_caldav_do_addcustomproperty($res, $varname, $varvalue);

Remarks

This property adds a form variable and the corresponding value. For information on form variables and how they are managed, please refer to the CustomProperties properties.

Example using the AddCustomProperty method:

CalDAVControl.Reset() CalDAVControl.AddCustomProperty("propname1", "propvalue1") CalDAVControl.AddCustomProperty("propname2", "propvalue2") Example using Custom Property arrays: CalDAVControl.Reset() CalDAVControl.CustomPropertyCount = 2 CalDAVControl.CustomPropertyName (0) = "propname1" CalDAVControl.CustomPropertyValue(0) = "propvalue1" CalDAVControl.CustomPropertyName (1) = "propname2" CalDAVControl.CustomPropertyValue(1) = "propvalue2"

Config Method (IPWorks_CalDAV Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworks_caldav_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CopyCalendarEvent Method (IPWorks_CalDAV Class)

Copy events to a new location.

Object Oriented Interface

public function doCopyCalendarEvent($sourceresourceuri, $destinationresourceuri);

Procedural Interface

ipworks_caldav_do_copycalendarevent($res, $sourceresourceuri, $destinationresourceuri);

Remarks

The CopyCalendarEvent method will copy the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.

This method is associated with the Depth property. If Depth is set to "0", the class will copy only SourceResourceURI. If Depth is set to "infinity", the class will copy SourceResourceURI and its entire subtree to the relative locations.

If the user has acquired a LockCalendar of infinite depth on either DestinationResourceURI or any collection it is under, SourceResourceURI will be added to that lock.

Note that neither Yahoo nor Google CalDAV servers support locking, copying, or moving calendar resources.

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

CreateCalendar Method (IPWorks_CalDAV Class)

Creates a new calendar collection resource.

Object Oriented Interface

public function doCreateCalendar($resourceuri);

Procedural Interface

ipworks_caldav_do_createcalendar($res, $resourceuri);

Remarks

The CreateCalendar method creates a new calendar collection resource. A server MAY restrict calendar collection creation to particular collections. Creating calendar collections is not supported by all CalDAV servers. Some calendar stores only support one calendar per user (or principal), and those are typically pre-created for each account.

The following properties are used to create a new calendar collection resource:

• Description
• DisplayName
• Timezone

The following example shows how to create a simple new calendar collection resource with Yahoo Calendar. CalDAVS1.DisplayName = "Testing Create Calendar method"; CalDAVS1.Description = "Test Calendar"; CalDAVS1.CreateCalendar("https://caldav.calendar.yahoo.com/dav/userid/Calendar/TestCal1");

Note that Google does not support creating a new calendar through CalDAV. It must be created through the Google calendar web interface.

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

DeleteCalendarEvent Method (IPWorks_CalDAV Class)

Delete a resource or collection.

Object Oriented Interface

public function doDeleteCalendarEvent($resourceuri);

Procedural Interface

ipworks_caldav_do_deletecalendarevent($res, $resourceuri);

Remarks

This method behaves independently of the Depth property. It is used to delete the resource or collection specified by ResourceURI. If ResourceURI denotes a non-collection resource, it is first removed from any collection in which it is contained, it is then removed from the server. If ResourceURI denotes a collection, the server behaves as if the command were issued with an infinite depth (i.e., all internal member URIs denoting single resources or collections are deleted).

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar).

DoEvents Method (IPWorks_CalDAV Class)

Processes events from the internal message queue.

Object Oriented Interface

public function doEvents();

Procedural Interface

ipworks_caldav_do_doevents($res);

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

ExportICS Method (IPWorks_CalDAV Class)

Generates an event from the properties in the iCal (.ICS) format.

Object Oriented Interface

public function doExportICS();

Procedural Interface

ipworks_caldav_do_exportics($res);

Remarks

The ExportICS method is used to create a calendar object and export it in the iCal/ICS format, which can then be saved to disk and imported using any calendar software, even those that do not support CalDAV. The ExportICS method will create the exact same data as the PutCalendarEvent method sends when adding or updating an event to a calendar.

Note that if ExportICS is called immediately after a successful GetCalendarEvent, the unmodified calendar returned from the CalDAV server will be returned. However if any properties are changed between the GetCalendarEvent and ExportICS calls, the class will generate and return a brand new event.

The following properties are used when creating a request with PutCalendarEvent or ExportICS, and will be filled after calling GetCalendarEvent or ImportICS. These will also be available from inside the EventDetails event, which is fired for each event received from the CalDAV server in response to a GetCalendarReport.

GetCalendarEvent Method (IPWorks_CalDAV Class)

Retrieves a single event from the CalDAV server.

Object Oriented Interface

public function doGetCalendarEvent($resourceuri);

Procedural Interface

ipworks_caldav_do_getcalendarevent($res, $resourceuri);

Remarks

This method retrieves a single event from a CalDAV server. The ResourceURI points to the exact location of the iCal (*.ics) file you wish to retrieve. (If you do not know the URL of the event you need, you can use the GetCalendarReport method along with the ReportFilter property to find it.)

The event will be fetched using the WebDAV GET method. The full response is delivered through the Transfer event and the HTTP response headers through the Header event. After an event is retrieved with this method, the class parses the calendar data into properties. You may then edit these properties and use PutCalendarEvent to update the calendar event resource.

The following properties are used when creating a request with PutCalendarEvent or ExportICS, and will be filled after calling GetCalendarEvent or ImportICS. These will also be available from inside the EventDetails event, which is fired for each event received from the CalDAV server in response to a GetCalendarReport.

GetCalendarOptions Method (IPWorks_CalDAV Class)

Retrieves options for the ResourceURI to determines whether it supports calendar access.

Object Oriented Interface

public function doGetCalendarOptions($resourceuri);

Procedural Interface

ipworks_caldav_do_getcalendaroptions($res, $resourceuri);

Remarks

This method sends an OPTIONS HTTP request to the indicated ResourceURI. The server will respond with an 200 OK HTTP message, and the supported options will fire one-by-one in the Header event. If a server supports CalDAV calendar access, the "DAV" header will contain the string "calendar-access". The allowable CalDAV and WebDAV methods may also be returned in the "Allow" header.

For instance, the following headers may be returned from a call to the GetCalendarOptions method:

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar.

GetCalendarReport Method (IPWorks_CalDAV Class)

Generates a report on the indicated calendar collection resource.

Object Oriented Interface

public function doGetCalendarReport($resourceuri);

Procedural Interface

ipworks_caldav_do_getcalendarreport($res, $resourceuri);

Remarks

This method is used to send a calendar-query request to the calendar located at the specified ResourceURI. The ReportFilter can be used to filter out and return only the calendar events you wish to receive. The response to a calendar-query report will be parsed by the class, and information about the individual events contained within shall be fired in the EventDetails event.

The following properties are used when creating a request with PutCalendarEvent or ExportICS, and will be filled after calling GetCalendarEvent or ImportICS. These will also be available from inside the EventDetails event, which is fired for each event received from the CalDAV server in response to a GetCalendarReport.

For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

GetFreeBusyReport Method (IPWorks_CalDAV Class)

Generates a report as to when the calendar owner is free and/or busy.

Object Oriented Interface

public function doGetFreeBusyReport($resourceuri);

Procedural Interface

ipworks_caldav_do_getfreebusyreport($res, $resourceuri);

Remarks

This method sends a free-busy-query request to the calendar at the specified ResourceURI. . The CalDAV server will return a list of FREEBUSY elements, which will be fired in the FreeBusy event and also stored in the FreeBusy collection. Each FREEBUSY element contains a type (BUSY, FREE, BUSY-TENTATIVE, etc.) and a date range.

Note that the ReportFilterStartDate property is required for a Free/Busy report. The ReportFilterEndDate property is optional. These are the only two ReportFilters used by the GetFreeBusyReport request, all other filters will be ignored.

Note that Google Calendar does not currently support Free/Busy reporting.

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

ImportICS Method (IPWorks_CalDAV Class)

Imports calendar data (contained in an ICS file) into the class's property list.

Object Oriented Interface

public function doImportICS($calendardata);

Procedural Interface

ipworks_caldav_do_importics($res, $calendardata);

Remarks

This method is used to load calendar data from an external source into the class. You may then submit this data with a call to PutCalendarEvent. If you edit any of the class properties between importing and calling PutCalendarEvent, the class will re-generate the PUT request itself. If no properties are changed, the imported data will be submitted unaltered when calling PutCalendarEvent.

As the calendar data is imported, the class will scan CalendarData for any calendar events. Each time a calendar event is discovered, the EventDetails event will fire, and the calendar event properties will be updated.

After ImportICS completes, the calendar event properties will be set to the most recent calendar event found in CalendarData.

Interrupt Method (IPWorks_CalDAV Class)

Interrupt the current method.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

ipworks_caldav_do_interrupt($res);

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

LockCalendar Method (IPWorks_CalDAV Class)

Obtain a lock for a specified calendar resource.

Object Oriented Interface

public function doLockCalendar($resourceuri);

Procedural Interface

ipworks_caldav_do_lockcalendar($res, $resourceuri);

Remarks

This method will request a new lock to be placed on ResourceURI in the user's name so that only the user can operate on it. The method is linked to a number of properties that it uses to generate the lock request:

This method is associated with the Depth property. If Depth is set to "0", the class will lock only ResourceURI and its properties. If Depth is set to "infinity", the class will lock ResourceURI and its entire subtree.

If MoveCalendarEvent or CopyCalendarEvent are used to place a resource or collection in a location under a resource locked with "infinity", the new resource or collection will be added to the lock. Any lock on a collection will prevent non-lock owners from adding resources to that collection.

Note that while the Yahoo CalDAV server does accept LockCalendar and UnLockCalendar requests, the server does not respect resource locks (either on events or on the entire calendar). The Google CalDAV sever does not support either of these requests, and will respond with an HTTP protocol error: 405 Method Not Allowed. Also, neither Yahoo nor Google CalDAV servers support copying or moving calendar resources.

MoveCalendarEvent Method (IPWorks_CalDAV Class)

Moves one calendar resource to a new location.

Object Oriented Interface

public function doMoveCalendarEvent($sourceresourceuri, $destinationresourceuri);

Procedural Interface

ipworks_caldav_do_movecalendarevent($res, $sourceresourceuri, $destinationresourceuri);

Remarks

This method will move the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.

This method is associated with the Depth property. If Depth is set to "0", the class will move only SourceResourceURI. If Depth is set to "infinity", the class will move SourceResourceURI and its entire subtree to locations relative to it.

If the user has acquired a lock of infinite depth (via LockCalendar) on either DestinationResourceURI or any collection it is under, SourceResourceURI will be added to that lock.

Note that neither Yahoo nor Google CalDAV servers support locking, copying, or moving calendar resources.

There is no standard format for resource URIs. Google for instance, uses "https://www.google.com/calendar/dav/" plus your email address to access the default calendar. So "https://www.google.com/calendar/dav/username@gmail.com/" is the base URI for the default calendar. If you have multiple calendars, replace the email address portion above with the Id of the calendar, plus "@group.calendar.google.com/". For instance: "https://www.google.com/calendar/dav/ev3nkr4ua83jej7q32oumn5eeo@group.calendar.google.com/". For Google, calendar events are stored in the "/events/" path. To retrieve a report on a calendar, you'd add "/events/" to one of the above paths. For example: CalDAV.GetCalendarReport("https://www.google.com/calendar/dav/username@gmail.com/events/"); Leaving the "/events/" out of the URI will result in an HTTP protocol error: 405 Method not allowed.

To add or retrieve an event, add the UID of the event you're creating or retrieving plus ".ics" to the path. Note that when putting an event with the PutCalendarEvent method, if the resourceURI and the UID do not match Google will create the event using the UID stored in the UID property. The actual location of will be newly added event will be returned in a "Location" header. This is the resource URI you must use to retrieve the event with GetCalendarEvent. For example: CalDAV.UID = "1234567890"; CalDAV.PutCalendarEvent("https://www.google.com/calendar/dav/username@gmail.com/events/1234567890.ics");

Yahoo uses a different format for CalDAV access. Yahoo's ResourceURIs always start with "https://caldav.calendar.yahoo.com/dav/" plus your user name, plus "/Calendar/" plus the name of your calendar. For instance: "https://caldav.calendar.yahoo.com/dav/username/Calendar/Your_Name" for the default calendar. (Yahoo uses your name to create the default calendar). When using the CreateCalendar event to create a new calendar, replace "Your_Name" in the URI with the desired name of your new calendar. Event resources are located directly under the "/Calendar/Calendar_Name/" path. Like Google, the UID and filename portion of the resource URI must match, but Yahoo will actually return an HTTP protocol error if they differ. The examples below show a few possible transactions: CalDAVS1.User = "username"; CalDAVS1.Password = "password"; CalDAV.DisplayName = "My Hockey Calendar"; CalDAV.CreateCalendar("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/"); CalDAV.StartDate = "20100401T040000"; CalDAV.EndDate = "20100401T060000"; CalDAV.UID = "qwerty1234567"; CalDAV.Summary = "First Practice"; CalDAV.Location = "Rink on 1st and main"; CalDAV.EventType = vEvent; CalDAV.PutCalendarEvent("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/qwerty1234567.ics"); CalDAV.GetCalendarReport("https://caldav.calendar.yahoo.com/dav/username/Calendar/Hockey_Calendar/");

PutCalendarEvent Method (IPWorks_CalDAV Class)

Adds a calendar resource at the specified ResourceURI using the CalDAV PUT method.

Object Oriented Interface

public function doPutCalendarEvent($resourceuri);

Procedural Interface

ipworks_caldav_do_putcalendarevent($res, $resourceuri);

Remarks

This method adds a new event to the calendar collection at the specified ResourceURI. The ResourceURI must be a fully qualified URL to the location on the CalDAV server to which this event will be saved. If the ResourceURI already exists, the event at that URI will be overwritten.

NOTE: Some CalDAV servers (Yahoo for example) require that the UID and the filename portion of the URI match. For example, if the UID is "hello_world" then the ResourceURI parameter of the PutCalendarEvent should be "https://caldav.calendar.yahoo.com/dav/user_name/Calendar/My_Calendar/hello_world.ics". If the UID and filename portion of the URI do not match, the Yahoo CalDAV server will return a "302 Found" response indicating that the requested resource resides under a different URI. (Meaning the event was not added to the calendar)

The following properties are used when creating a request with PutCalendarEvent or ExportICS, and will be filled after calling GetCalendarEvent or ImportICS. These will also be available from inside the EventDetails event, which is fired for each event received from the CalDAV server in response to a GetCalendarReport.

EndTransfer Event (IPWorks_CalDAV Class)

Fired when a document finishes transferring.

Object Oriented Interface

public function fireEndTransfer($param);

Procedural Interface

ipworks_caldav_register_callback($res, 4, array($this, 'fireEndTransfer'));

Parameter List

 'direction'

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (IPWorks_CalDAV Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworks_caldav_register_callback($res, 5, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

EventDetails Event (IPWorks_CalDAV Class)

Fires for each calendar event received.

Object Oriented Interface

public function fireEventDetails($param);

Procedural Interface

ipworks_caldav_register_callback($res, 6, array($this, 'fireEventDetails'));

Parameter List

 'resourceuri'
 'responsestatus'
 'etag'
 'calendardata'

Remarks

This event fires for each VEVENT, VTODO, VJOURNAL, or VFREEBUSY event received in response to a GetCalendarReport request. The ResourceURI parameter indicates the location of this particular event on the CalDAV server, and the ETag parameter is used to indicate the current state of the calendar event. If the ETag is different from the value you have cached for the current ResourceURI, it means the event has changed on the server since the last time you updated your cache. ResponseStatus indicates the HTTP status of CalDAV server received when attempting to retrieve this particular ResourceURI when it was building the report. The CalendarData parameter contains the raw calendar entry as returned by the CalDAV server. This data is also parsed into the following properties, and are valid for the current ResourceURI only inside this event.

• Alarms
• Attendees
• Categories
• Classification
• Completed
• Created
• CustomProperties
• Depth
• Description
• DisplayName
• Duration
• EndDate
• EventType
• LastModified
• Location
• Organizer
• Priority
• Recurrence
• Sequence
• StartDate
• Status
• Summary
• Timestamp
• Timezone
• Transparency
• UID
• URL

Note that for a large calendar you may not wish to return the full contents of each calendar event, as this could be a substantially large amount of data. In this case, set the ReportFilterReturnCalendarData property to false, and only the ResourceURI, ResponseStatus, and ETag parameters will be returned by the CalDAV server for each calendar event. The contents of the event will not be returned, and the CalendarData parameter will be empty.

*The ResourceURI and the URL property are not the same. The URL property is an iCal field, and the ResourceURI is the actual location of the resource on the CalDAV server. Some CalDAV servers may force the URL to match the ResourceURI, but the URL should be treated as a separate user-defined entity by the user, and it should not be expected to match the ResourceURI. Likewise, ResponseStatus and Status are not the same. Status is the status of the event (TENTATIVE, CONFIRMED, CANCELLED, etc). ResponseStatus is the HTTP status received when the CalDAV server attempted to retrieve the current event when constructing a report.

FreeBusy Event (IPWorks_CalDAV Class)

Fires for each Free/Busy element received in the response.

Object Oriented Interface

public function fireFreeBusy($param);

Procedural Interface

ipworks_caldav_register_callback($res, 7, array($this, 'fireFreeBusy'));

Parameter List

 'busytype'
 'busyrange'

Remarks

This event fires for each FREEBUSY element received in response to a GetFreeBusyReport request.

The Free/Busy information will also be stored in the FreeBusy collection.

Header Event (IPWorks_CalDAV Class)

This event is fired every time a header line comes in.

Object Oriented Interface

public function fireHeader($param);

Procedural Interface

ipworks_caldav_register_callback($res, 8, array($this, 'fireHeader'));

Parameter List

 'field'
 'value'

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (IPWorks_CalDAV Class)

This event fires once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

ipworks_caldav_register_callback($res, 9, array($this, 'fireLog'));

Parameter List

 'loglevel'
 'message'
 'logtype'

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"

Redirect Event (IPWorks_CalDAV Class)

This event is fired when a redirection is received from the server.

Object Oriented Interface

public function fireRedirect($param);

Procedural Interface

ipworks_caldav_register_callback($res, 10, array($this, 'fireRedirect'));

Parameter List

 'location'
 'accept'

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the class fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.

SetCookie Event (IPWorks_CalDAV Class)

This event is fired for every cookie set by the server.

Object Oriented Interface

public function fireSetCookie($param);

Procedural Interface

ipworks_caldav_register_callback($res, 11, array($this, 'fireSetCookie'));

Parameter List

 'name'
 'value'
 'expires'
 'domain'
 'path'
 'secure'

Remarks

The SetCookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SSLServerAuthentication Event (IPWorks_CalDAV Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

ipworks_caldav_register_callback($res, 12, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
 'certsubject'
 'certissuer'
 'status'
 'accept'

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (IPWorks_CalDAV Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworks_caldav_register_callback($res, 13, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (IPWorks_CalDAV Class)

Fired when a document starts transferring (after the headers).

Object Oriented Interface

public function fireStartTransfer($param);

Procedural Interface

ipworks_caldav_register_callback($res, 14, array($this, 'fireStartTransfer'));

Parameter List

 'direction'

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Status Event (IPWorks_CalDAV Class)

This event is fired when the HTTP status line is received from the server.

Object Oriented Interface

public function fireStatus($param);

Procedural Interface

ipworks_caldav_register_callback($res, 15, array($this, 'fireStatus'));

Parameter List

 'httpversion'
 'statuscode'
 'description'

Remarks

HTTPVersion is a string containing the HTTP version string as returned from the server (e.g., "1.1").

Transfer Event (IPWorks_CalDAV Class)

This event is fired while a document transfers (delivers document).

Object Oriented Interface

public function fireTransfer($param);

Procedural Interface

ipworks_caldav_register_callback($res, 16, array($this, 'fireTransfer'));

Parameter List

 'direction'
 'bytestransferred'
 'percentdone'
 'text'

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
