Extension:Page Forms/MediaWiki red links code change

The relevant change in the main MediaWiki code to allow for red links to point to an 'add data' form is in the file [MEDIAWIKI_DIR]/includes/Linker.php, within the function makeBrokenLinkObj. The specific change depends on the version of MediaWiki.

MediaWiki 1.10 and earlier
Around line 331 of Linker.php, the code: if ( '' == $query ) { $q = 'action=edit'; } else { $q = 'action=edit&'.$query; }		$u = $nt->escapeLocalURL( $q ); should be changed to: # special patch for Semantic Forms - see if a default form # exists for this title, and, if so, link to the form for # adding this page, instead of the regular Edit page $u = sffAddDataLink($nt); if ( '' == $u ) { if ( '' == $query ) { $q = 'action=edit'; } else { $q = 'action=edit&'.$query; }			$u = $nt->escapeLocalURL( $q ); }

MediaWiki 1.11 and later
Around line 340 of Linker.php, the code: if( $nt->getNamespace == NS_SPECIAL ) { $q = $query; } else if ( '' == $query ) { $q = 'action=edit'; } else { $q = 'action=edit&'.$query; }		$u = $nt->escapeLocalURL( $q );

should be changed to: # special patch for Semantic Forms - see if a default form # exists for this title, and, if so, link to the form for # adding this page, instead of the regular Edit page $u = sffAddDataLink($nt); if( $nt->getNamespace == NS_SPECIAL ) { $q = $query; $u = $nt->escapeLocalURL( $q ); } else if ('' == $u ) { if ( '' == $query ) { $q = 'action=edit'; } else { $q = 'action=edit&'.$query; }			$u = $nt->escapeLocalURL( $q ); }

Assuming you already have Semantic MediaWiki and Semantic Forms installed and running, that's all you need to do.
