1. Remove the security links before wiki-parsing

$wgHooks['ParserBeforeStrip'][] = 'removeSecurityLinks'; function removeSecurityLinks(&$parser,&$text,&$strip_state) { global $deny; if ($deny) { $text = new Article(Title::newFromText('Action not permitted')); $text = $text->fetchContent(0,false,false); $deny = false; } else $text = preg_replace("/\\[{2}\\s*:?security\\s*:[^\\]]+?\\]{2}[\r\n]?/i",,$text); }

1. Security information functions

$wgHooks['ParserAfterTidy'][] = 'renderSecurityInfo'; function renderSecurityInfo(&$parser,&$text) { global $secinfo,$action,$wgHooks; if ($GLOBALS['rsi-done']++) return; #allowExpandables($parser,$text);

if ($secinfo && $action == 'view') $text .= "\n

$info .= "

$a requires the user to be $b$comment
