User Login

[AtomicRax]

I'm trying to authenticate user login information. Currently I have:

 

if(isset($_POST[user])) {
$user = $_POST[user];
$password = $_POST[password];
$saltedPassword = crypt($password, $mdsalt);

$passQuery = mysql_query("SELECT * FROM user_accounts WHERE user='$user' LIMIT 1");
$password = mysql_result($passQuery,0,"password");

if($saltedPassword == $password) {
// Login
}
else {
// Error
}

 

 

How ever, I get this error message:

mysql_result(): supplied argument is not a valid MySQL result resource

 

I've double checked the information I'm trying to login with, it's all correct..but for some reason I still get this message.

Make sure you sanitize all user inputs
