How come every time i the mysql_num_rows() function returns with no results i get this error?
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /customers/svolvar-jff.net/svolvar-jff.net/httpd.www/new/admin/add_user.php on line 109
Is there any other functions i can use to see how many results i get from a query without getting an error from php?
