我正在使用Magento 1.9.0.1。
我创建了一个新的扩展程序，现在当我运行此功能时：
$coupon = Mage::getModel('salesrule/rule');
$couponCollection = $coupon->getCollection();
foreach($couponCollection as $c){
$CouponDiscount = $c->getDiscountAmount();
}
变量$CouponDiscount应该给我使用优惠券代码的折扣金额。 但不是这样，它会从我的新分机中获得金额。
这是我的新扩展程序和我认为重要的文件：

$installer->addAttribute("order", "discount_total", array("type"=>"varchar"));
$installer->endSetup();
请告诉我在新扩展中需要更改的内容，以便可以达到这两个变量。我希望使用默认的getDiscountAmount()功能来应用优惠券代码的金额。
你能告诉我在新的扩展中我需要改变什么吗？
答案 0 :(得分：1)
快一点......
$coupon = Mage::getModel('salesrule/rule');
$couponCollection = $coupon->getCollection();
$CouponDiscount = 0
foreach($couponCollection as $c){
$CouponDiscount += $c->getDiscountAmount();
}
快速浏览一下，您将$ CouponDiscount重置为foreach最后一次迭代所指示的内容。当你好像想要获得总折扣时。我能正确理解你的问题吗？
在您的自定义模块之外，您可以检索每件商品的折扣金额值。
$quote = Mage::getSingleton('checkout/session')->getQuote();
foreach ($quote->getAllItems() as $item){
echo $item->getDiscountAmount();
}
折扣保存在discount_amount和base_discount_amount列下的sales_flat_quote_item表中
