获取已购买的可下级产品ID的订单ID

Question

如何从购买的下级产品中获取订单ID？

请检查我以下代码：

$purchased = Mage::getResourceModel('downloadable/link_purchased_collection')
        ->addFieldToFilter('customer_id', $customer_id)
        ->addOrder('created_at', 'desc');

$purchasedItems = Mage::getResourceModel('downloadable/link_purchased_item_collection')
        ->addFieldToFilter('purchased_id', array('in' => $purchasedIds))
        ->addFieldToFilter('status',
            array(
                'nin' => array(
                    Mage_Downloadable_Model_Link_Purchased_Item::LINK_STATUS_PENDING_PAYMENT,
                    Mage_Downloadable_Model_Link_Purchased_Item::LINK_STATUS_PAYMENT_REVIEW
                )
            )
        )
        ->setOrder('item_id', 'desc');


foreach ($items as $item)
{ 
    -- Here I wand to get Order id of each items ---
}

Answer 1

这不是最好的解决方案，因为它涉及循环中的负载，但它比没有更好。

foreach ($items as $item)
{ 
    $orderItemId = $item->getOrderItemId();
    $orderItem = Mage::getModel('sales/order_item')->load($orderItemId);
    $orderId = $orderItem->getOrderId();//this is what you need
}

我认为简单的查询轻松为您工作

    $readConnection = Mage::getSingleton('core/resource')->getConnection('core_read');
    $sfoi = Mage::getSingleton("core/resource")->getTableName('sales_flat_order_item');
    foreach ($items as $item)
    { 
        $itemId=$item->getId();
        $query="SELECT order_id FROM $sfoi WHERE item_id=$itemId";
        $results = $readConnection->fetchAll($query);
        $orderId=$results[0]['order_id'];    
    }
