标签: magento cart observers

我正在网站上工作,我想在购物车总额和总额中加上/减去费用。我正在启动此活动以捕获购物车详细信息。sales_order_save_after。在观察者中,我使用此代码获得了价格

public function modifyPrice(Varien_Event_Observer $obs)
        {


       $getotal = Mage::helper('checkout')->getQuote()->getGrandTotal();
       $totals = Mage::getSingleton('checkout/session')->getQuote()->getTotals(); 
       $subtotal = $totals["subtotal"]->getValue();
}.

但我不知道如何从总数中加/减金额而不是相应地更新。谢谢提前

搜索后我发现了这个教程http://magento.ikantam.com/qa/how-add-discount-total-magento。在折扣模型类中,我可以添加/减去自定义价格到购物车总数,如:

 public function collect(Mage_Sales_Model_Quote_Address $address) {
            if ($address->getData('address_type') == 'billing')
                return $this;

                $discount = Mage::helper('my_module')->getCurrentdiscount(); // Custom percentage

                $grandTotal = $address->getGrandTotal();
                $baseGrandTotal = $address->getBaseGrandTotal();

                $totals = array_sum($address->getAllTotalAmounts());
                $baseTotals = array_sum($address->getAllBaseTotalAmounts());

                $address->setFeeAmount(-$totals * $discount / 100);
                $address->setBaseFeeAmount(-$baseTotals * $discount / 100);

                $address->setGrandTotal($grandTotal + $address->getFeeAmount());
                $address->setBaseGrandTotal($baseGrandTotal + $address->getBaseFeeAmount());
        return $this;
    }
