Magento - 在自定義報價總計字段應用稅

Question

我爲Magento創建了一個附加模塊，它爲報價添加了自定義總字段。 Magento收取附加費，包括稅費。我已經成功地獲得了該模塊，爲報價添加附加費，並且在結帳頁面上的總額是正確的。

我的問題是，當試圖將稅款應用於附加費用，以便將其納入並顯示在結帳頁面上的稅收字段中時。目前它只包括產品稅和運費。

我已經設法計算了附加稅的稅額，但不能獲得適用於報價的稅額，以便它在稅收領域顯示，但也不認爲我的方法是非常正確的。任何幫助將非常感激。

我設法解決這個問題，使用下面的代碼。不是最好的解決方案，但花了數小時試圖做到這一點，並沒有得到任何快速。 Asterix的需要被替換。

    $this->_taxConfig  = Mage::getSingleton('tax/config'); 
    $this->_store = Mage::app()->getStore(); 
} 

protected function _calculateTax(Mage_Sales_Model_Quote_Address $address) 
{ 
    $calculator  = Mage::getSingleton('tax/calculation'); 
    $calculator->setCustomer($address->getQuote()->getCustomer()); 

    $inclTax  = $this->_taxConfig->priceIncludesTax($this->_store); 

    $taxRateRequest = $calculator->getRateRequest(
     $address, 
     $address->getQuote()->getBillingAddress(), 
     $address->getQuote()->getCustomerTaxClassId(), 
     $this->_store 
    ); 

    $taxRateRequest->setProductClassId(Mage::getStoreConfig('*****/surcharges/tax_class', $this->_store)); 

    $rate = $calculator->getRate($taxRateRequest); 

    if($rate > 0.0) { 
     $baseTax = $calculator->calcTaxAmount($address->getBaseSurchargePriceAmount(), $rate, $inclTax, true); 
     $tax = $address->getQuote()->getStore()->convertPrice($baseTax, false); 

     $address->addTotalAmount('tax', $tax); 
     $address->addBaseTotalAmount('tax', $baseTax); 

     $rates = array(); 
     foreach ($address->getAppliedTaxes() as $rate) { 
     $rate['amount'] = $rate['amount'] + $tax; 
     $rate['base_amount'] = $rate['base_amount'] + $baseTax; 
     $rates[] = $rate; 
     } 

     $address->setAppliedTaxes($rates); 

     if($inclTax) {

     $address->setBaseGrandTotal($address->getBaseGrandTotal() - $baseTax); 
     }
