庫存數量未在magento中下訂單後更新

Question

下面的代碼工作正常，我在magento下訂單，但庫存數量未更新其保持原樣，但是當我從前端下訂單時，股票更新，但是當我使用下面的代碼下訂單時，庫存數量保持不變。 默認郵件在下訂單後成功發送給客戶。

添加下面的代碼將更新數量，一切工作正常。

//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();
