I have some code to another engine
if (preg_match ("/href|url|http|www|.ru|.com|.net|.info|.org/i", $_POST['comments']) || preg_match ("/href|url|http|www|.ru|.com|.net|.info|.org/i", $_POST['name'])){$stop[] = "Sorry, post links in the comments is forbidden!";$CN_HALT = TRUE;}
how integrate this code in q2a?
