Dettagli

Array of allowed values for the "action" parameter for normal pages.

This method of defining custom actions replaces the deprecated UnknownAction hook. For details about how to migrate existing hook code to the class-based approach, see the migration section of the hook page .

Syntax is:

  • 'foo' => 'ClassName' - Load the specified class which subclasses Action
  • 'foo' => true - Load the class FooAction which subclasses Action
  • 'foo' => false - The action is disabled; show an error message

Default value

Example

There is a lot you can do with a custom action, and the best method of discovery is to browse the Action, FormAction and FormlessAction classes in the core MediaWiki code (as these are the classes you will be extending) and to look at examples of pages that provide similar function to what you require, either in the core or in stable and well-supported extensions.

The following example covers the most common use-case, namely generating a custom page for the action, possibly with some extra URL arguments.

// Register the action in the array of available actions.
// If you only need to support more recent versions of MediaWiki, register the action using
// extension.json, instead.
$wgActions['example_action'] = 'ExampleAction';

class ExampleAction extends Action {

	// This action is called 'example_action'.  This class will only be invoked when the specified
	// action is requested.
	public function getName() {
		// This should be the same name as used when registering the action in $wgActions.
		return 'example_action';
	}

	// This is the function that is called whenever a page is being requested using this action.
	// You should not use globals $wgOut, $wgRequest, etc.  Instead, use the methods provided
	// by the Action class (e.g. $this->getOutput()), instead.
	public function show() {
		// Create local instances of the context variables we need, to simplify later code.
		$out = $this->getOutput();
		$request = $this->getRequest();

		// The view is the same for the main page and the talk page, so if we're on the
		// talk page then we need to change $Title to point to the subject page instead.
		$title = $this->page->getTitle();
		if ( $title->isTalkPage() ) {
			$title = $title->getSubjectPage();
		}

		// Set page title.
		$out->setPageTitle( 'Example Page Title' );

		// Get some parameters from the URL.
		$param = $request->getIntOrNull( 'example_param' );

		// Do some internal stuff to generate the content (placed in $output).

		// Output the results.
		$out->addHTML( $output );
		// or
		$out->addWikiText( $output );
	}
}

Disable an action

To disable an action just add the following e.g. for the "raw" action to your "LocalSettings.php" file:

$wgActions['raw'] = false;
Unsetting core actions will probably cause things to complain loudly.
