[support] getting $_GET excluding $_GET['q']

I've other parameters in the query string just because I don't want them to be positional. url is something like /blabla/bubu/bibi/?id=stuff I'd like to use: $form['#action'] = url($_GET['q'], drupal_get_destination()); but the id query string part get encoded to %3Fid%3D81152 Is there any other way to avoid positional parameters in query string? or is there a function to obtain the referring url? thx -- Ivan Sergio Borgonovo http://www.webthatworks.it
