Always sanitize inputs; never store plain passwords.

$user = mysql_real_escape_string($_GET['user']);
$pw = md5($_GET['pw']); //or your favorite hash

 

Then check that only 1 row exists that has columns matching that username and that password.

You need to either provide some sort of code we can work with or be a little more specific.
