在Magento结帐确认上显示礼品卡金额

实际上，我在我的结帐确认中检索到了订单详细信息

$order_details = Mage::getModel('sales/order')->loadByIncrementId($order_id); 

$discount_amount = $order_details->_data["discount_amount"]; 

并在结帐确认时显示折扣

$order_details = Mage::getModel('sales/order')->loadByIncrementId($order_id); 

$discount_amount = $order_details->_data["discount_amount"]; 

但当我想和你一起看礼品卡的时候

$giftcard_amount = $order_details->_data["giftcard_amount"]; 

---

它没有显示，实际上它有什么问题，谢谢

尝试打印

$order\u details->getData（）

并检查

giftcard\u amount

值是否存在。我发现它[礼品卡]=>数组（[15]=>AW\u giftcard\u Model\u Quote\u giftcard Object@slimshaddyyyyy您需要从giftcard Object检索giftcard\u amount
