Details edit

  • &$linksUpdate: the LinksUpdate object

LinksUpdate is called when a page has new content that needs to be processed for links (or, more generally, metadata), whether it got created, edited or restored. When a page is moved, the hook is called for both the old and new version of the page [1].
