Index contains the array index of the file about to be processed, and the FileCompressedName, FileDecompressedName, FileCompressedSize (decompression only), and FileDecompressedSize fields of the Files collection for this index contain more detailed information about the file about to be processed.

When extracting, an alternate location may be specified by trapping the event, and modifying FileDecompressedName and/or ExtractToPath. If FileDecompressedName is set to an empty string, the file will not be written to disk. If WriteToProgressEvent is true, the file will still be decompressed, and the data may be extracted through the Progress event.

Procedural Interface

ipworkszip_officedoc_register_callback($res, 7, array($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.

Procedural Interface

ipworkszip_officedoc_register_callback($res, 8, array($this, 'fireEvalEntity'));

The Value parameter contains a suggested value for the entity (normally the entity name itself). You may set Value to a value of your choice, which will be later passed into the text stream.

IgnorableWhitespace Event (IPWorksZip_OfficeDoc Class)

Fired when a section of ignorable whitespace is encountered.

Object Oriented Interface

public function fireIgnorableWhitespace($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 9, array($this, 'fireIgnorableWhitespace'));

Parameter List

 'text'

Remarks

The ignorable whitespace section is provided by the Text parameter.

Meta Event (IPWorksZip_OfficeDoc Class)

Fired when a meta section is encountered.

Object Oriented Interface

public function fireMeta($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 10, array($this, 'fireMeta'));

Parameter List

 'text'

Remarks

The Meta event is fired whenever a meta information section (<! ..text... >) is found in the document.

The full text of the meta section is provided by the Text parameter.

Overwrite Event (IPWorksZip_OfficeDoc Class)

Fired whenever a file exists and may be overwritten.

Object Oriented Interface

public function fireOverwrite($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 11, array($this, 'fireOverwrite'));

Parameter List

 'filename'
 'overwrite'

Remarks

Overwrite is fired when a file is about to be overwritten, and would overwrite an existing file. The event is fired during decompression.

Filename contains the full name of the file, specified with its pathname.

Overwrite specifies whether or not the file will be overwritten. For Zip, Jar, and Tar, this is equal by default to the value of the OverwriteFiles property. For Gzip, this value defaults to true.

Either of the parameters may be changed when the event is fired. Changing the value of Overwrite will override the default behavior of the class, and cause the file to be overwritten or not overwritten, depending on the value set. If Filename is changed, the value of Overwrite will be ignored, and the file will be written with the specified name. If a file of the new name also exists this file will be silently overwritten.

PI Event (IPWorksZip_OfficeDoc Class)

Fired when a processing instruction section is encountered.

Object Oriented Interface

public function firePI($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 12, array($this, 'firePI'));

Parameter List

 'text'

Remarks

The PI event is fired whenever a processing instruction section (<? ..text... ?>) is found in the document.

The full text of the processing instruction is provided by the Text parameter.

Progress Event (IPWorksZip_OfficeDoc Class)

Fired as progress is made.

Object Oriented Interface

public function fireProgress($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 13, array($this, 'fireProgress'));

Parameter List

 'data'
 'filename'
 'bytesprocessed'
 'percentprocessed'

Remarks

The Progress event is automatically fired as compression or decompression is performed. When WriteToProgressEvent is true, the output data is provided through the Data parameter, allowing for it to be streamed out.

Filename contains the name of the file being written. If no file is being written, Filename will contain an empty string, and the output data will be provided exclusively through this event.

BytesProcessed contains the total number of uncompressed bytes processed. PercentProcessed contains the percent of uncompressed bytes processed, corresponding roughly to the running time of the operation.

For Gzip extraction only, BytesProcessed and PercentProcessed will reflect the number of compressed bytes extracted, as it is generally impossible to predetermine the total uncompressed size.

If WriteToProgressEvent is false, Data will contain null.

SpecialSection Event (IPWorksZip_OfficeDoc Class)

Fired when a special section is encountered.

Object Oriented Interface

public function fireSpecialSection($param);

Procedural Interface

ipworkszip_officedoc_register_callback($res, 14, array($this, 'fireSpecialSection'));

Config Settings (OfficeDoc Class)

Trappable Errors (OfficeDoc Class)

Errors

The following errors may be generated by the class. Note that frequently the error message will contain more specific information than what is listed here.

Note that some non-fatal errors may be trapped and explicitly ignored in the Error event. This will allow the class to continue operation even in case of error.
