Simple query question

[eluser]TheFuzzy0ne[/eluser]
I'd try escaping it differently:

Code:

$second_verify = $this->CI->db->query("
                SELECT *
                FROM `user`
                WHERE
                    `user_name` = '" . $this->db->escape($username_login) . "' and
                    `password` = md5(concat(md5('" . $this->db->escape($password_login) . "'), salt))
            ");

The code above is untested.

You may find something along those lines might work better.
