无法在 magento 订单总额中添加发票费用税

Question

我正在开发 magento 1.7。我正在开发支付网关，我已经添加了发票费用现在我必须在税组添加发票费用的税金

请任何人帮助解决这个问题，这是按照我的代码进行的

<?php

class ***_******_Model_Quote_TaxTotal
    extends Mage_Sales_Model_Quote_Address_Total_Tax
{

    public function collect(Mage_Sales_Model_Quote_Address $address)
    {
        $quote = $address->getQuote();
        if (($quote->getId() == null)
            || ($address->getAddressType() != "shipping")
        ) {
            return $this;
        }

        $payment = $quote->getPayment();
        if (($payment->getMethod() != 'invoice')
            && (!count($quote->getPaymentsCollection()))
        ) {
            return $this;
        }

        try {
            /**
             * Instead of relying on hasMethodInstance which would not always
             * work when i.e the order total is reloaded with coupon codes, we
             * try to get the instance directly instead.
             */
            $methodInstance = $payment->getMethodInstance();
        } catch (Mage_Core_Exception $e) {
            return $this;
        }

        if (!$methodInstance instanceof Mage_Payment_Model_Method_Abstract) {
            return $this;
        }

        if ($methodInstance->getCode() != 'invoice') {
            return $this;
        }

        $fee = $methodInstance->getAddressInvoiceFee($address);
        if(Mage::getStoreConfig('payment/invoice/tax_class') == '' ){
            return $this;
        }

        $invoiceFee = $baseInvoiceFee = Mage::getStoreConfig('payment/invoice/_fee');

        $fee = Mage::helper('invoice')->getInvoiceFeeArray($invoiceFee, $address, null);

        if (!is_array($fee)) {
            return $this;
        }
        $address->setTaxAmount($address->getTaxAmount() + 5454+ $fee['taxamount']);
        $address->setBaseTaxAmount(
            $address->getBaseTaxAmount() + 5454+ $fee['base_taxamount']
        );

        $address->setInvoiceTaxAmount($fee['taxamount']);
        $address->setBaseInvoiceTaxAmount($fee['base_taxamount']);
        return $this;
    }

}

这是 config.xml

    <sales>
        <quote>
            <totals>
                <fee>
                    <class>invoice/sales_quote_address_total_fee</class>
                </fee>
                <invoicetax>
                    <class>invoice/quote_taxTotal</class>
                    <after>subtotal,discount,shipping,tax</after>
                    <before>grand_total</before>
                </invoicetax>
            </totals>
        </quote>
    </sales>

你的代码必须关注我已经修改了你的代码
