Tracking is a new feature available since phpdocx 9 for Premium licenses only.
This functionality allows to:
- Enable and disable tracking in a document created from scratch or in an already existing DOCX.
- Track added, replaced and deleted contents with the compatible methods.
- Include the people participating in the document generation without regarding their origin: local, online provider.
- Accept or reject the contents tracked in a document.
- Protect a document by allowing changes only in tracked contents.
- Obtain all information regarding tracking: contents marked to be added, replaced and deleted and participants.
To activate change tracking, just call the enableTracking method. All new contents or changes will be added with the corresponding MS Word tracking tags. Use the method disableTracking to mark the end of change tracking.
The following example creates a new document with a paragraph, enables tracking for the user "phpdocx", adds two more paragraphs and finally disables tracking before saving the document:
More complex contents as images, sections, headers or footers are also compatible:
It is mandatory to specify the name of the tracking user in enableTracking.
These are the compatible methods with the tracking feature:
E.g.: it is possible to open an existing DOCX and track changes such as the deletion of a table or the replacement of a placeholder:
Contents and styles tracked in a document can be accepted, and thus included as definitive in the document, or rejected, that means, deleted.
The next example accepts the changes for the paragraph that contains "www.phpdocx.con" and rejects the last table of the document:
These two methods support: inserted contents, inserted rPr and pPr styles, removed styles, removed rows, changed column sizes, removed contents.
The method getDocxPathQueryInfo allows to obtain dinamically and on real time the list and information of all contents and styles tracked in a document, either created from scratch or an existing one.
Supported types in tracking queries are: tracking-insert, tracking-delete, tracking-run-style, tracking-paragraph-style, tracking-table-style, tracking-table-grid and tracking-table-row.
Among the extensive information that the Indexer class gets it figures the list of the people participating in the document.
MS Word 2013 and higher allows to add one or more people as contributors of a document. The addPerson method adds new people to a document:
This method allows to indicate the provider, e.g., specifying if a user is local or is online in the MS Word cloud.
All tracking methods include several options in order to serve for almost any task. You can check all available methods and options on the API documentation.
