以编程方式为客人设置 magento 税率 ID 的正确方法是什么

发布于 2024-09-26 12:03:15 字数 113 浏览 1 评论 0原文

我正在尝试根据优惠券代码为客人（未登录）设置税率。

我已经尝试了我能想到的每一个单例，但即使手动设置我想要设置的 customertaxrateid 也遇到了麻烦。

有什么想法吗？

所以更新并回答...我在放置代码时犯了一个非常愚蠢的错误，但在发现网络上完全缺乏有关这些主题的信息后...我想我会分享一些代码...评论而不是我的自定义解决方案我正在使用...但它有效！

代码需要添加到：
/app/code/core/Mage/Tax/Model/Calculation.php

$couponCode = Mage::getSingleton('checkout/cart')->getQuote()->getCouponCode();
if (!empty($couponCode)) {

    $db = Mage::getSingleton('core/resource')->getConnection('core_read');
    $query = ""//put your sql query here since magento makes it hard to respect MVC when a group of setters and getters think you are running mysql4 even though you are using mysql5
            $result = $db->query($query);

    while ($row = $result->fetch() ) {
        //lazy method to avoid the need for more error handling                 
        $customerTaxClass = $row['class_id'];
    }

}

应该在 getRateRequest 函数创建要返回的 $request 之前完成。

so update and answer... i made a really stupid mistake placing my code but after finding a complete lack of information about these subjects on the web... i thought i would share some code... commented instead of the custom solution i am using... but it works!!!

the code needs to be added in:
/app/code/core/Mage/Tax/Model/Calculation.php

$couponCode = Mage::getSingleton('checkout/cart')->getQuote()->getCouponCode();
if (!empty($couponCode)) {

    $db = Mage::getSingleton('core/resource')->getConnection('core_read');
    $query = ""//put your sql query here since magento makes it hard to respect MVC when a group of setters and getters think you are running mysql4 even though you are using mysql5
            $result = $db->query($query);

    while ($row = $result->fetch() ) {
        //lazy method to avoid the need for more error handling                 
        $customerTaxClass = $row['class_id'];
    }

}

it should be done in the getRateRequest function before it creates the $request to return.
