禁用付款选项 - 仅限特定产品 - magento的货到付款

时间：2012-12-23 13:30:37

标签： magento

我正在使用Magento 1.4.1.1，我想禁用某些产品的付款选项。我想只显示某些产品的货到付款方式，需要隐藏其他产品。

有什么机构可以帮我吗？我怎么能管理这个？管理员有没有选择，或者我需要自定义代码。如果是这样，你能不能给我一个代码和文件的确切路径？

提前谢谢。

过滤付款方式的一种不引人注目的方式是实施名为payment_method_is_active的事件的观察员

的步骤
1 GT;在config.xml中注册事件：'payment_method_is_active'。 在app / code / local / MagePsycho / Paymentfilter / etc / config.xml中添加以下xml代码：

...
<global>
    ...
    <events>
        <payment_method_is_active>
            <observers>
                <paymentfilter_payment_method_is_active>
                    <type>singleton</type>
                    <class>paymentfilter/observer</class>
                    <method>paymentMethodIsActive</method>
                </paymentfilter_payment_method_is_active>
            </observers>
        </payment_method_is_active>
    </events>
    ...
</global>
...

2 - ;实现观察者模型 创建观察者文件：app / code / local / MagePsycho / Paymentfilter / Model / Observer.php并粘贴以下代码：

<?php
/**
 * @category   MagePsycho
 * @package    MagePsycho_Paymentfilter
 * @author     magepsycho@gmail.com
 * @website    http://www.magepsycho.com
 * @license    http://opensource.org/licenses/osl-3.0.php  Open Software License (OSL 3.0)
    */
class MagePsycho_Paymentfilter_Model_Observer {

    public function paymentMethodIsActive(Varien_Event_Observer $observer) {
        $event           = $observer->getEvent();
        $method          = $event->getMethodInstance();
        $result          = $event->getResult();
        $currencyCode    = Mage::app()->getStore()->getCurrentCurrencyCode();


            if($someTrueConditionGoesHere){
                $result->isAvailable = true;
            }else{
                $result->isAvailable = false;
            }

    }

}

首先创建一个产品属性（名称：'magepal_payment_filter_by_product'，输入：yes / no）以识别这些产品。

例如Magento v1.7的基础你可以

  1. 自动启用付款模块，以编程方式查看https://stackoverflow.com/a/14023210/1191288

  2. 启用所有适用的付款模块并过滤显示

    3. 的模块

    在/app/code/local/MagePal/PaymentFilterByProduct/etc/config.xml 

    <?xml version="1.0"?>
<config>
    <modules>
        <MagePal_PaymentFilterByProduct>
            <version>1.0.1</version>
        </MagePal_PaymentFilterByProduct>
    </modules>
    <global>
        <helpers>
            <paymentfilterbyproduct>
                <class>MagePal_PaymentFilterByProduct_Helper</class>
            </paymentfilterbyproduct>
            <payment>
                <rewrite>
                    <data>MagePal_PaymentFilterByProduct_Helper_Payment_Data</data>
                </rewrite>
            </payment>            
        </helpers>      
    </global>
</config>

    在/app/code/local/MagePal/PaymentFilterByProduct/Helper/Payment/Data.php 

    <?php
class MagePal_PaymentFilterByProduct_Helper_Payment_Data extends Mage_Payment_Helper_Data
{

    public function getStoreMethods($store = null, $quote = null)
    {   
        $methods = parent::getStoreMethods($store, $quote);

        if(!Mage::getStoreConfig('paymentfilterbyproduct/general_option/paymentfilterbyproduct_enable', Mage::app()->getStore()) || !$quote){
            return $methods;
        }

        //get a list of product in cart
        $cart = Mage::getSingleton('checkout/session');

        $specialProductInCart = array();

        foreach ($cart->getQuote()->getAllItems() as $item) {
            $specialProductInCart[] = $item->getMagepalPaymentFilterByProduct();                 
        }

        // if special product in cart 
        // need to if check $item->getMagepalPaymentFilterByProduct() return 'yes/no' or '0/1)
        if(in_array('yes', $specialProductInCart)){
           $filter_csv = Mage::getStoreConfig('paymentfilterbyproduct/filter_option/paymentfilter_special_products', Mage::app()->getStore()); 
        }
        else{
            $filter_csv = Mage::getStoreConfig('paymentfilterbyproduct/filter_option/paymentfilter_all_product', Mage::app()->getStore());
        }

        $filter_array = explode(",", $filter_csv);

        foreach ($methods as $k => $method){
            if(!in_array($method->getCode(), $filter_array))
                unset($methods[$k]);       
        }//methods

        return $methods;
    }
}
