Task: update two tables with one query for specific cells. Here is the code
$q = " START TRANSACTION; UPDATE users SET email='$email',flname='$flname',fllogin='$fllogin',password='$pass',country_code='$country_code' where pk_user = '$userkey'; UPDATE comments,comments_m,comments_f SET email='$email' where id_commenter='$$userkey'; COMMIT;"
right?
