php - 在 magento 下订单后库存数量未更新

Question

下面的代码可以很好地让我在magento下订单，但是库存数量没有更新，它保持原样，但是当我从前端下订单时，订单被下达并且库存被更新，但是当我使用下面时代码下订单，库存数量保持不变。 下订单后，默认邮件也会成功发送给客户。

      $id=$custid; // get Customer Id

添加以下代码将更新数量，一切正常。

//get total quantity
$totalqty = (int)Mage::getModel('cataloginventory/stock_item')
           ->loadByProduct($productId)
           ->getQty();
//calculate new quantity
$newqty = $totalqty-$product['qty'];

//update new quantity
Mage::getModel('cataloginventory/stock_item')
       ->loadByProduct($productId)
       ->setQty($newqty)
       ->save();
