我需要限制税额。所以我去了Mage/Tax/Model/Calculation.php
然后查找 calcTaxAmount()
税务申请功能。 我需要限制所有人都在结账时纳税的税收一页税应为零
所以
public function calcTaxAmount($price, $taxRate, $priceIncludeTax = false, $round = true)
{
$billing = Mage::getModel('checkout/session')->getQuote()->getCustomerTaxvat();
if($billing != "" )
{
return 0;
}
$taxRate = $taxRate / 100;
if ($priceIncludeTax) {
$amount = $price * (1 - 1 / (1 + $taxRate));
} else {
$amount = $price * $taxRate;
}
if ($round) {
return $this->round($amount);
}
return $amount;
}
我添加了新条件。它在一些多商店的商店工作。只有一家商店无法正常运作。它导致用户无法注册,并且addtocart不适用于该特定商店。我发现了 getQuote 这个问题。我删除新的条件,如下工作正常。
旧功能: -
public function calcTaxAmount($price, $taxRate, $priceIncludeTax = false, $round = true)
{
$taxRate = $taxRate / 100;
if ($priceIncludeTax) {
$amount = $price * (1 - 1 / (1 + $taxRate));
} else {
$amount = $price * $taxRate;
}
if ($round) {
return $this->round($amount);
}
return $amount;
}
答案 0 :(得分:1)
尝试下面的代码希望这有帮助。
public function calcTaxAmount($price, $taxRate, $priceIncludeTax = false, $round = true)
{
$currenQuoteId = Mage::getSingleton('checkout/session')->getQuoteId();
$store = Mage::getSingleton('core/store')->load(Mage::app()->getStore()->getId());
$quote = Mage::getModel('sales/quote')->setStore($store)->load($currenQuoteId);
$billing = $quote->getCustomerTaxvat();
if($billing != "" )
{
return 0;
}
$taxRate = $taxRate / 100;
if ($priceIncludeTax) {
$amount = $price * (1 - 1 / (1 + $taxRate));
} else {
$amount = $price * $taxRate;
}
if ($round) {
return $this->round($amount);
}
return $amount;
}

我被固定在流下: -
而不是在Calculation.php中使用GetQuote使用会话变量
<强>法/结帐/型号/类型/ Onepage.php 强>
功能名称: - 公共功能saveBilling($ data,$ customerAddressId)
$assign = $this->getQuote()->getCustomerTaxvat();
if ($assign !="")
{
$this->_checkoutSession->setVatSession($assign);
}
else
{
$this->_checkoutSession->unsVatSession();
}
在 return array();
之前的onepage.php中添加以上代码,这意味着最后一个功能。
现在接下来获取会话变量
法/税务/型号/ Calculation.php
public function calcTaxAmount($price, $taxRate, $priceIncludeTax = false, $round = true)
{
$sessionaccess = Mage::getModel('checkout/session')->getVatSession();
if($sessionaccess != "")
{
return 0;
}
$taxRate = $taxRate / 100;
if ($priceIncludeTax) {
$amount = $price * (1 - 1 / (1 + $taxRate));
} else {
$amount = $price * $taxRate;
}
if ($round) {
return $this->round($amount);
}
return $amount;
}
