Okey, I got another problem regarding SQL queries.
I couldn't be bothered creating a new topic just for that when I already have this one..

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\wamp\www\DB Class 2\includes\classes\user.php on line 126

user.php
php Code:
public function user_is_logged_in () { $sql = sprintf(" SELECT `%s` FROM `%s` WHERE `%s` = '%s' LIMIT 1", $this-> db-> col[ 'user_id'], $this-> db-> table[ 'users'], $this-> db-> col[ 'user_session'], session_id()); $query = $this-> db-> query($sql); if(! mysql_num_rows($query)) { return false; } return true; }
