Php magento中信用卡折扣的自定义价格规则

我希望有人能帮我制定一个我一直有问题的价格规则。如果有人用指定的信用卡付款，我想打一定的折扣

例如，假设我想对Visa信用卡给予一定的折扣，即如果客户使用Visa信用卡付款，他必须获得{xy}金额的折扣

我已经尝试了很多，我扩展了Mage_SalesRule_Model_Rule_Condition_Address类，并添加了一个新属性，我在管理站点上获得了创建规则的选项

但问题是，当我使用信用卡visa进行支付并再次回到支付模式以更改模式并使用其他支付卡时，它会获取上一张支付卡的信息，并对未指定的信用卡提供折扣。 我的扩展课程是：

class Alw_ManageProduct_Model_Condition_Address extends Mage_SalesRule_Model_Rule_Condition_Address

    public function loadAttributeOptions()
    {
        $attributes = array(
            'base_subtotal' => Mage::helper('salesrule')->__('Subtotal'),
            'total_qty' => Mage::helper('salesrule')->__('Total Items Quantity'),
            'weight' => Mage::helper('salesrule')->__('Total Weight'),
            'payment_method' => Mage::helper('salesrule')->__('Payment Method'),
            'shipping_method' => Mage::helper('salesrule')->__('Shipping Method'),

如果有人可以的话，请帮帮我……

我这里也有同样的问题。你解决了吗？我也在找类似的东西。如果有人有更多关于网关的文档，If可能会很有趣
