$wgExtensionCredits['parserhook'][] = array( 'name' => "IsAllowedHook", 'author' => 'User:Nad', 'description' => 'Adds a new hook called "IsAllowed" which is called from the User::isAllowed method.', 'url' => 'http://www.organicdesign.co.nz/Extension:IsAllowedHook.php', 'version' => DFO_VERSION );

1. Create a new User class by extending the existing one

$User = get_class($wgUser); $User2 = $User.'2'; eval("class $User2 extends $User".' {

# Override the isAllowed method to call the new IsAllowed hook function isAllowed($action = "") { $result = NULL; wfRunHooks("IsAllowed",array(&$this,$action,&$result)); return $result === NULL ? $result = parent::isAllowed($action) : $result; }

}');

1. Replace the $wgUser object with an identical User2 instance

$oldUser = $wgUser; $wgUser = new $User2(); foreach(array_keys(get_class_vars($User)) as $k) $wgUser->$k = $oldUser->$k;
