Detailed Description

Factory for handling the special page list and generating SpecialPage objects.

To add a special page in an extension, add to $wgSpecialPages either an object instance or an array containing the name and constructor parameters. The latter is preferred for performance reasons.

The object instantiated must be either an instance of SpecialPage or a sub-class thereof. It must have an execute() method, which sends the HTML for the special page to $wgOut. The parent class has an execute() method which distributes the call to the historical global functions. Additionally, execute() also checks if the user has the necessary access privileges and bails out if not.

To add a core special page, use the similar static list in SpecialPageFactory::$list. To remove a core static special page at runtime, use a SpecialPage_initList hook.

Note
There are two classes called SpecialPageFactory. You should use this first one, in namespace MediaWiki\Special, which is a service. \SpecialPageFactory is a deprecated collection of static methods that forwards to the global service.

1.17

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Special\SpecialPageFactory::__construct ( Config $config,
Language $contLang )

Member Function Documentation

◆ capturePath()

MediaWiki\Special\SpecialPageFactory::capturePath ( Title $title,
IContextSource $context,
LinkRenderer $linkRenderer = null )

Just like executePath() but will override global variables and execute the page in "inclusion" mode.

Returns true if the execution was successful or false if there was no such special page, or a title object if it was a redirect.

Also saves the current $wgTitle, $wgOut, $wgRequest, $wgUser and $wgLang variables so that the special page will get the context it'd expect on a normal request, and then restores them to their previous values after.

Parameters
Title$title
IContextSource$context
LinkRenderer | null$linkRenderer(since 1.28)
Returns
string HTML fragment

Definition at line 588 of file SpecialPageFactory.php.

References $context, $linkRenderer, $ret, $title, $wgLang, $wgOut, $wgRequest, and $wgTitle.

◆ executePath()

MediaWiki\Special\SpecialPageFactory::executePath ( Title & $title,
IContextSource & $context,
$including = false,
LinkRenderer $linkRenderer = null )

Returns a title object if the page is redirected, false if there was no such special page, and true if it was successful.
