magento轮小计，总计和税款 [英] magento round subtotal, total and tax

问题描述

我已经安装了ET货币管理器，以便通过Gramm以低于<价格的价格出售产品.每克0.01.

问题是，有时这会导致小计，税款和总计只有半美分的价格……(除了贝宝问题之外)这会使客户感到困惑并且不可接受

因此，我正在寻找一种解决方案，以将小计，税金和总计值四舍五入到小数点后两位.

我知道ET货币管理器具有从结帐中排除"的选项，但是这会导致其他问题，因此与该问题无关(如果在此处未找到解决方案，我将单独询问该问题)

我通过更改以下函数设法对总数进行了舍入:

app \ code \ core \ Mage \ Sales \ Model \ Quote \ Address \ Total \ Grand.php

public function collect(Mage_Sales_Model_Quote_Address $address)
    {
        $grandTotal     = $address->getGrandTotal();
        $baseGrandTotal = $address->getBaseGrandTotal();

        $totals     = array_sum($address->getAllTotalAmounts());
        $baseTotals = array_sum($address->getAllBaseTotalAmounts());

        $address->setGrandTotal(round(($grandTotal+$totals),2)); //Modificated
        $address->setBaseGrandTotal(round(($baseGrandTotal+$baseTotals),2)); //Modificated
        //$address->setGrandTotal($grandTotal+$totals);  --Original
        //$address->setBaseGrandTotal($baseGrandTotal+$baseTotals); --Original
        return $this;
    } 

是否可以同时对小计和税额进行四舍五入? 我尝试在上述目录中的其他文件中执行此操作，但是没有结果.

解决方案

我知道这个问题比较老，但是最近我遇到了完全相同的问题.所以这是我的解决方案，到目前为止似乎还行得通.

public function collect(Mage_Sales_Model_Quote_Address $address)
{
    $grandTotal         = round($address->getGrandTotal(), 2);
    $baseGrandTotal     = round($address->getBaseGrandTotal(), 2);
    $subTotal           = round($address->getSubtotal(), 2);
    $baseSubTotal       = round($address->getBaseSubtotal(), 2);
    $taxAmount          = round($address->getTaxAmount(), 2);
    $baseTaxAmount      = round($address->getBaseTaxAmount(), 2);
    $shippingAmount     = round($address->getShippingAmount(), 2);
    $baseShippingAmount = round($address->getBaseShippingAmount(), 2);

    $address->setSubtotal($subTotal);
    $address->setBaseSubtotal($baseSubTotal);

    $address->setTaxAmount($taxAmount);
    $address->setBaseTaxAmount($baseTaxAmount);     

    $address->setShippingAmount($shippingAmount);
    $address->setBaseShippingAmount($baseShippingAmount);

    $address->setGrandTotal($grandTotal + $subTotal + $shippingAmount + $taxAmount);
    $address->setBaseGrandTotal($baseGrandTotal + $baseSubTotal + $baseShippingAmount + $baseTaxAmount);

    return $this;
}

I have installed the ET Currency Manager in order to sell products by gramm with prices < 0.01 per gramm.

The problem is that this sometimes leads to subtotals, taxes and totals with half cents...which (apart from the paypal problem) is confusing for the customer and not acceptable

Therefore I am searching for a solution to round the subtotal, tax and grand total value to 2 decimal places.

I know that the ET Currency Manager has the option "exclude from checkout" but that leads to other problems wherefore it is not relevant for this question (if I do not get a solution here I will ask this question seperately)

I managed to round the grand total by changing the following function:

app\code\core\Mage\Sales\Model\Quote\Address\Total\Grand.php

public function collect(Mage_Sales_Model_Quote_Address $address)
    {
        $grandTotal     = $address->getGrandTotal();
        $baseGrandTotal = $address->getBaseGrandTotal();

        $totals     = array_sum($address->getAllTotalAmounts());
        $baseTotals = array_sum($address->getAllBaseTotalAmounts());

        $address->setGrandTotal(round(($grandTotal+$totals),2)); //Modificated
        $address->setBaseGrandTotal(round(($baseGrandTotal+$baseTotals),2)); //Modificated
        //$address->setGrandTotal($grandTotal+$totals);  --Original
        //$address->setBaseGrandTotal($baseGrandTotal+$baseTotals); --Original
        return $this;
    } 

Is there a way to simultaneously round the subtotal and tax? I tried to do so in the other files in the above mentioned directory but without result.

解决方案

I know this question is rather old but I had exactly the same problem recently. So here is my solution which seems to work fine so far.

public function collect(Mage_Sales_Model_Quote_Address $address)
{
    $grandTotal         = round($address->getGrandTotal(), 2);
    $baseGrandTotal     = round($address->getBaseGrandTotal(), 2);
    $subTotal           = round($address->getSubtotal(), 2);
    $baseSubTotal       = round($address->getBaseSubtotal(), 2);
    $taxAmount          = round($address->getTaxAmount(), 2);
    $baseTaxAmount      = round($address->getBaseTaxAmount(), 2);
    $shippingAmount     = round($address->getShippingAmount(), 2);
    $baseShippingAmount = round($address->getBaseShippingAmount(), 2);

    $address->setSubtotal($subTotal);
    $address->setBaseSubtotal($baseSubTotal);

    $address->setTaxAmount($taxAmount);
    $address->setBaseTaxAmount($baseTaxAmount);     

    $address->setShippingAmount($shippingAmount);
    $address->setBaseShippingAmount($baseShippingAmount);

    $address->setGrandTotal($grandTotal + $subTotal + $shippingAmount + $taxAmount);
    $address->setBaseGrandTotal($baseGrandTotal + $baseSubTotal + $baseShippingAmount + $baseTaxAmount);

    return $this;
}
