我需要限制税额。所以我去了
Mage/Tax/Model/Calculation.php
然后找到calcTaxAmount()
报税功能。 我需要限制所有在结账时输入税负的税收,一页税应该为零
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 $amount;
}
我添加了新条件。它在一些多商店的商店中运作。只有一家店无法正常营业。它会导致用户无法注册,并且 addtocart 不适用于该特定商店。我发现了 getQuote 的问题。我删除了如下的新条件,工作正常。
旧功能:-
public function calcTaxAmount($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 $amount;
}
尝试下面的代码希望这有帮助。
public function calcTaxAmount($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 $amount;
}
我被固定在以下流程:-
使用会话变量代替在 Calculation.php 中使用 GetQuote
法师/结账/模型/类型/Onepage.php
函数名称:- 公共函数 saveBilling($data, $customerAddressId)
$assign = $this->getQuote()->getCustomerTaxvat();
if ($assign !="")
{
$this->_checkoutSession->setVatSession($assign);
}
else
{
$this->_checkoutSession->unsVatSession();
}
在 onepage.php 中的
return array();
之前添加以上代码,这意味着该函数的最后一个。
现在下面开始访问会话变量
法师/税收/模型/Calculation.php
public function calcTaxAmount($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;
}
