尝试在 Magento 中计算单个商品的销售税而不显示含税价格

Question

Magento CE 版本。 1.7.0.2

我正在尝试从我们的 Magento 商店获取一些订单数据，以集成到我们的其他业务软件中。就我而言，我需要计算单个商品的价格加税。以下代码仅在 在目录中显示产品价格 设置为 Include 或 Both（在系统 > 配置 > 销售 > 税收中）时有效。如何在网站显示不含税价格的同时计算商品的税费？

$customer_tax_class = Mage::getModel('tax/calculation')->getRateRequest()->getCustomerClassId();
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku',$skunumber);
$my_price = Mage::helper('tax')->getPrice($_product, $_product->getPrice(), true, $shippingAddress, $billingAddress, $customer_tax_class);

我也尝试过使用它，但我仍然得到不含税的价格（除非我更改上述显示设置）：

$_finalPriceInclTax = Mage::helper('tax')->getPrice($_product, $_product->getFinalPrice(), true, $shippingAddress, $billingAddress, $customer_tax_class); 

我知道这一定是可能的，因为 Magento 在您下订单时会计算税款。任何帮助将不胜感激。

获得所需的所有参数需要一段时间，因为我们使用的是高度自定义的结帐，但这是最终对我有用的方法

    $my_quote = Mage::getSingleton('checkout/session')->getQuote();             
    $my_customer = Mage::getSingleton('customer/session')->getCustomer();
    $my_items = $quote->getAllItems();
    $taxClassId = $qty = $price = array();
    foreach ($my_items as $key => $my_item) {
      //get the price plus tax for this item
      // get the product tax id for this item first.
      $my_sku = $my_item->getSku();
      $qty[$my_sku] = $my_item->getQty(); 
      $taxClassId[$my_sku] = Mage::getModel('catalog/product')->load(
                  $my_item->getProductID())->getData("tax_class_id");
      $price[$my_sku] = Mage::getModel('catalog/product')->load(
                  $my_item->getProductID())->getData("price");
    }
    $my_store = Mage::app()->getStore($my_quote->getStoreId());
    $ctc = $my_customer->getTaxClassId();
    $tax_calc = Mage::getSingleton('tax/calculation');
    $tax_rate_req = $tax_calc->getRateRequest(
        $shippingAddress,
        $billingAddress,
        $ctc,
        $my_store);
    if(is_Array($taxClassId)){
    foreach($taxClassId as $key => $value){
      $my_rate[$key] = Mage::getSingleton('tax/calculation')->getRate(
                 $tax_rate_req->setProductClassId($value));
    }    
    foreach($my_rate as $key => $value){
      foreach($split_filter as $my_key => $my_value){
         //This is used because we split orders based on their shipping method
        if($my_value == $key){
        // This code might malfunction if tax rate is an integer (i.e. 8%)
        if(is_float($value)){
          $my_price = $price[$key];
          $my_qty = $qty[$key];
          $taxy = Mage::getModel('tax/calculation')->calcTaxAmount(
             $my_price, 
             $value
          );
          $price_withtax = $my_price + $taxy;
          // still need to multiply times qty ordered to get row totals
          $row_total = ($price_withtax * $my_qty);
        } else {// $value is not a float.
          $row_total = ($price[$key] * $qty[$key]);
        }
          // then add to other rows to get subtotal
          $subtotal_with_tax += $row_total;
      }
    }
