Hi everyone :) So partly to get an answer, and partly to boost my post rankings for the week I have a question. I am attempting to write an authentication function which would query a database, check the username/password and return true if it matches. If it doesn't match, then it shouldn't return anything and they are denied access. Here is the code for the function: <?PHP

        function authentication(){
        if($user && $pass) { // Keep in mind, PASSWORD has meaning in MySQL
            // Do your string sanitizing here
            // (e.g. - $user = mysql_real_escape_string($_POST['user']);)
            $loginQuery = "SELECT * FROM login WHERE user='".$user."' AND Userpass='".$pass."' LIMIT 0,1;";
            $loginResult = mysql_query($loginQuery) or die("Wrong data supplied or database error"  .mysql_error());
            while($row1 = mysql_fetch_array($loginResult)) {
                $_SESSION['user'] = $row1['User'];
                $_SESSION['loggedin'] = "YES";
                $authenticated = "true";
            }
        }
    }return $authenticated;

?> Change:

}return $authenticated; to return $authenticated; } else it will never return the value from the function. But it will always give you undefined variable notice
