          $results = '';
          foreach(...) {
               ...
               $results .= $get_row['name'].' x '.$value.' @ &pound;'.number_format($get_row['price'], 2).' = &pound;'.number_format($sub, 2).'<a href="cart.php?remove='.$id.'">[-]</a> <a href="cart.php?add='.$id.'">[+]</a> <a href="cart.php?delete='.$id.'">[Delete]</a><br />';
          }
          return $results;
     }
?>



<input type="hidden" name="cart1" value="<?php echo cart1 (); ?>">
<input type="hidden" name="cart2" value="<?php echo cart2 (); ?>">
