php – Magento：结帐时额外收费的税收错误

我已经为我的结帐添加了额外的费用,但税额没有正确计算.

如果我执行$this-> _calculateTax($address),则税额不会正确累加;在收集功能中,它加起来包括税,但我的税额仍然是.

如果是var_dump,则在$address-> setAppliedTaxes($prevIoUsAppliedTaxes)行之后设置应用税;我确实看到了正确的金额.它转储了两次,第一次看到正确的税额只是我的额外费用,第二次是正确的总税额.但是在前端它显示了税收而没有我的额外费用税.

关于这可能是什么的任何线索？

XML包含这个：

<sales>
        <quote>
            <totals>
                <printPrepCosts>
                    <class>Company_Customer_Model_Quote_Address_Total_PrintPrepCosts</class>
                    <after>subtotal</after>
                    <before>tax</before>
                </printPrepCosts>
            </totals>
        </quote>
    </sales>

我已经将以下行添加到我的calcTax函数中,这确实修复了总计,但TAX的数量仍然是关闭的.

$address->setTaxAmount($tax);
  $address->setBaseTaxAmount($baseTax);

输出 – 示例

Subtotal    € 67,50
printPrepCosts  € 40,00
Shipping    € 50,00
TAX     € 22,33
Total   € 187,43

我的不好,只有GoMage onepage checkout给出了正确的总计,购物车没有.常规的Magento onepage checkout也提供了错误的格式.

我找到了一个解决方法,它不是最好的解决方案,但确实有效:)

在我的地址中,我将税收设置为一个额外的变量,称为税,并在观察者中使用它来操纵税收.

class Company_Client_Model_Observer
{   
    public function setCorrectTax ($observer)
    {
        $quote = $observer->getQuote();
        foreach ($quote->getAllAddresses() as $address) {
            $printPrepCosts = $address->getPrintPrepcosts();
            if(!empty($printPrepCosts)) {
                $address->setTaxAmount($address->tax);
            }
        }
    }
}

和XML

<events>
    <sales_quote_collect_totals_after>
        <observers>
            <client>
                <type>singleton</type>
                <class>client/observer</class>
                <method>setCorrectTax</method>
            </client>
        </observers>
    </sales_quote_collect_totals_after>
    </events>
