some help with code please !!

[burnist]

Okay, I need some help with this code block. It worked fine on vb2 and now i've upgraded to vb3 it dosn't and im not shure if i missed anything else that needs changed. It is my own version of an itemshop. It takes the users money from the profile field, the cost of the item from the item table then subtracts the cost. Next it pulls the users current item puts a space then the item's id so str replace can be used not to limit the number of items a user can have.

PHP Code:

 if ($action == "buy"){
  $item = $_GET['item'];
  $itemquery = $DB_site->query("SELECT * FROM items WHERE id = '".$item."' ");
  $iteminfo = $DB_site->fetch_array($itemquery);
  if (($bbuserinfo["field5"] >= $iteminfo["price"])) {
    $newmoney = ($bbuserinfo["field5"]-$iteminfo["price"]);
    $newitems = $bbuserinfo['items']." ".$item;
    $DB_site->query("UPDATE userfield SET field5 = '".$newmoney."' WHERE userid = '".$bbuserinfo['userid']."';");
    $DB_site->query("UPDATE user SET items = '".$newitems."' WHERE userid = '".$bbuserinfo['userid']."';");
    $url = "shop.php?action=thanks";
    eval(print_standard_redirect('itemshop_purchaseokay'));
  } else 
eval(print_standard_error('itemshop_notenough'));
} 


It dosn't produce any parse errors or sql errors either so that all I can tell you about it.
