$_SESSION...

Hmm, hey.

I have this code (below) and it basically redeems voucher codes, anyway when I redeem one it:

a) changes my name to 1 (changes $_SESSION['logged_user'] from Tom to 1)
b) says the code isn't valid

If I vists redeem.php (the code below) it automatically changes my username to 1. >_> not in the db just the session. o.O

It worked (redeeming) then broke.

PHP Code:

---

<?php
session_start();
include 'config.php';
$code = clean($_POST['code']);
$usedby = $_SESSION['logged_user'];

if ($_SESSION['logged_user'] = true) {
    if ($_POST['submit']) {
        $checkcode = mysql_query("SELECT * FROM `codes`");
   $check = mysql_fetch_object($checkcode);
   
    if($check->code == $code) {
        $query = mysql_query("SELECT `amount` FROM `codes` WHERE `code` = '$code'");
        $rows = mysql_fetch_array($query);
$amount = $rows['amount'];
$query = mysql_query("SELECT `credits` FROM `users` WHERE `username` = '$usedby'");
$rows = mysql_fetch_array($query);
$credits = $rows['credits'];
    $newcredits = $amount + $credits;
        $update = mysql_query("UPDATE `users` SET `credits` = '$newcredits' WHERE `username` = '$usedby'"); 
        echo "Credit code redeemed! You now have $newcredits! Your name: $usedby";
        
    } else {
        echo "Code isn't valid.";
    }
    } else {
        echo "<form action=\"redeem.php\" method=\"POST\">
        Enter code: <input type=\"text\" size=\"16\" maxlength=\"12\" name=\"code\">
        </br>
        <input type=\"submit\" name=\"submit\" value=\"Redeem!\">";
     
    }
    } else {
        echo "Not logged in!";
    }

?>
