Magento - 从订单中获取价格规则

Question

有谁知道如何从订单中获得目录和购物车价格规则？

我知道我可以通过该方法从订单商品中获得折扣百分比getDiscountPercent(),但是如何获得应用于整个订单的所有规则？

例如,我有一条规则"客户组X可以获得商店中所有商品20%的折扣".

现在我想确定用户提交订单时实际应用了哪些规则.我需要这个订单导出界面,我必须提供用户获得的所有折扣.

提前致谢!

看看sales_flat_order_item桌子.有一个字段applied_rule_ids,它将为您提供应用于该项目的规则的ID.您还可以在此表中找到应用了多少折扣和百分比.

例

//The order I want to check
    $order_id = 859;

    //Get the list of items for your order
    $items = Mage::getModel('sales/order_item')
    ->getCollection()
    ->addFilter('order_id',array('eq'=>$order_id));

    //loop through each item
    foreach($items as $item){

        //if the item has not had a rule applied to it skip it
        if($item->getAppliedRuleIds() == '')continue;

        /*
        * I cant remember in the database they might be comma separated or space if multiple rules were applied
        * the getAppliedRuleIds() function is the one you want
        */
        foreach(explode(",",$item->getAppliedRuleIds()) as $ruleID){        

            //Load the rule object
            $rule = Mage::getModel('catalogrule/rule')->load($ruleID);

            // Throw out some information like the rule name what product it was applied to

            echo "<p>".$item->getSku()." had rule ".$rule->getName()."(".$item->getAppliedRuleIds().") applied </p>";
        }

    }
