Answer 1

You need to "return" the value. See the entry in the PHP manual for this. Basically, return means "exit this function now". Optionally, you can also provide some data that the function can return.

Just use the return statement:

 $value) {
          if ($value > 0) {
              if (substr($name, 0, 5) == 'cart_') {
                  $id = substr($name, 5, (strlen($name) - 5));
                  $get = mysql_query('SELECT id, name, price FROM products WHERE id=' . mysql_real_escape_string((int)$id));
                  while ($get_row = mysql_fetch_assoc($get)) {
                      $sub = $get_row['price'] * $value;
                      echo $get_row['name'] . ' x ' . $value . ' @ £' . number_format($get_row['price'], 2) . ' = £' . number_format($sub, 2) . '[-] [+] [Delete]
';
                  }
              }
              $total += $sub;
          }
      }

      return $total;
  }
?>
