The Preloader extension allows the creation of boilerplate text which will be inserted into the edit form when creating new pages. Different boilerplate text can be specified for different namespaces.

In addition, a new parser tag, <nopreload> is introduced, which is used to denote sections which should not be preloaded, ever; useful for instructions and advice on the boilerplate pages. This tag has no effect during a regular parse operation.


  • Extract archive content and place the file(s) in a directory called Preloader in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'Preloader' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


Configuration of the boilerplate sources is done via the $wgPreloaderSource configuration variable, which takes the following format:

$wgPreloaderSource[ NAMESPACE ] = PAGE TITLE;

For instance,

$wgPreloaderSource[ NS_MAIN ] = 'Template:Boilerplate';
$wgPreloaderSource[ NS_HELP ] = 'Template:Boilerplate help';

dictates that the boilerplate text for pages in the main namespace should be loaded from Template:Boilerplate, while pages in the Help namespace will be preloaded from Template:Boilerplate_help. Other namespaces have no boilerplate configured.
