PurgePage

The PurgePage extension provides the #purge parser function to MediaWiki. This parser function allows to trigger an update to a parser functions whenever the page where this function is used is updated.

Example usage

On page Foo add the following parser function call to the wikitext:

{{#purge:Bar}}

Now every time Foo is purged (e.g. every time it is edited and saved) Bar will also be updated.

This can be useful, when the content of Bar depends on Foo, e.g. when using a SemanticMediawiki query on Bar that contains data from Foo in the results.

Requirements

• PHP 5.4 or later
• MediaWiki 1.26 or later
