resource id #13


Recommended Posts

Hello everyone,


I am writing some code for a login script. I keep getting the error Resource ID #13. What does this mean and how can I fix it?


Here is the code that I am having trouble with

function user_id_from_username($username) {
    $username = sanitize($username);
    $query = mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'");

    return mysql_result($query, 0, 'user_id');

function login($username, $password) {
    $user_id = user_id_from_username($username);

    $username = sanitize($username);
    $password = md5($password);

    $query = "SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'";

    return (mysql_result(mysql_query($query), 0) == 1) ? $user_id : false;

Resource #13 is your connection.  Doesn't say much.


Break up the last line and tell us which line # you get the error on.


$query = mysql_query($query);

$count = mysql_result($query, 0);

return $count == 1 ? $user_id : false;
