A WikiPage osztály egy MediaWiki-oldalt és annak történetét jeleníti meg. It encapsulates access to page information stored in the database, and allows access to properties such as page text (in Wikitext format), flags, etc.

In theory, WikiPage is supposed to be the model object for pages, while the Article class handles the business and presentation functions.

Accessing a WikiPage object

Új WikiPage objektum készítése

Use a WikiPageFactory to create new WikiPage objects.

Metódusok

  • getContent( $audience ): Get the content of the latest revision, where $audience is one of:
    1. RevisionRecord::FOR_PUBLIC - to be displayed to all users
    2. RevisionRecord::FOR_THIS_USER - to be displayed to $wgUser
    3. RevisionRecord::RAW - get the text regardless of permissions
  • If the ContentHandler supports it, you can do something like the following to get the text of the latest revision in the main slot:
$text = $wikiPage->getContent( RevisionRecord::RAW )->getText();
