如何在Prestashop 1.6的发票页面中检查税务规则

检查正确的变量

在$order_invoice中找不到此数据。如果您想获得每种产品的税收规则，您需要检查$order_detail变量。从invoice.tpl提取：

<!-- PRODUCTS -->
{foreach $order_details as $order_detail}
{cycle values='#FFF,#DDD' assign=bgcolor}
<tr style="line-height:6px;background-color:{$bgcolor};">
    <!-- Here we've got one line, for one product -->
    <!-- This product's datas are stored in $order_detail -->
</tr>

您可以在$order_detail.tax_rate中找到税率。不幸的是，它总是返回0.000。

是。。。此数据未填充。。。悲伤的一天

创建OrderDetail覆盖

在override/classes/order/文件夹中创建OrderDetail.php文件，其中包含以下代码：

class OrderDetail extends OrderDetailCore
{
    /**
     * Get order products
     *
     * @return array Products with price, quantity (with taxe and without)
     */
    public function getProducts($products = false, $selectedProducts = false, $selectedQty = false)
    {
        if (!$products)
            $products = $this->getProductsDetail();
        $order = new Order($this->id_order);
        $customized_datas = Product::getAllCustomizedDatas($order->id_cart);
        $resultArray = array();
        foreach ($products as $row)
        {
            // Retrieve tax rate
            $product = new Product($row['product_id']);
            $row['tax_rate'] = $product->getTaxesRate();
            // Change qty if selected
            if ($selectedQty)
            {
                $row['product_quantity'] = 0;
                foreach ($selectedProducts as $key => $id_product)
                    if ($row['id_order_detail'] == $id_product)
                        $row['product_quantity'] = (int)($selectedQty[$key]);
                if (!$row['product_quantity'])
                    continue;
            }
            $this->setProductImageInformations($row);
            $this->setProductCurrentStock($row);
            $this->setProductCustomizedDatas($row, $customized_datas);
            // Add information for virtual product
            if ($row['download_hash'] && !empty($row['download_hash']))
            {
                $row['filename'] = ProductDownload::getFilenameFromIdProduct((int)$row['product_id']);
                // Get the display filename
                $row['display_filename'] = ProductDownload::getFilenameFromFilename($row['filename']);
            }
            $row['id_address_delivery'] = $order->id_address_delivery;
            /* Stock product */
            $resultArray[(int)$row['id_order_detail']] = $row;
        }
        if ($customized_datas)
            Product::addCustomizationPrice($resultArray, $customized_datas);
        return $resultArray;
    }
}

此覆盖允许我们编辑tax_rate值
我只是在getProducts()函数中添加了这两行：

foreach ($products as $row)
{
    // Retrieve tax rate
    $product = new Product($row['product_id']);
    $row['tax_rate'] = $product->getTaxesRate();
    // ...
}

创建OrderInvoice覆盖

在override/classes/order/文件夹中创建OrderInvoice.php文件
此类将包含与我们以前的覆盖相同的代码。只需更改第一行：

<?php
class OrderInvoice extends OrderInvoiceCore
{
    // Copy/Paste the same code
}

现在，您可以使用{$order_detail.tax_rate}显示每个产品的税率！！

(奖金(编辑您的模板

让我们更改此模板(此处：pdf/invoice.tpl(以添加"税务规则"列：

<tr style="line-height:4px;">
    <!-- Remove 10% from the first column header width -->
    <td style="text-align: left; background-color: #4D4D4D; color: #FFF; padding-left: 10px; font-weight: bold; width: {if !$tax_excluded_display}25%{else}35%{/if}">{l s='Product / Reference' pdf='true'}</td>
    ...
    <!-- Add our new column header, 10% width -->
    <td style="background-color: #4D4D4D; color: #FFF; text-align: right; font-weight: bold; width: 10%; white-space: nowrap;">{l s='Tax rate' pdf='true'}</td>
    ...
</tr>
<!-- PRODUCTS -->
{foreach $order_details as $order_detail}
{cycle values='#FFF,#DDD' assign=bgcolor}
<tr style="line-height:6px;background-color:{$bgcolor};">
    <!-- Remove 10% from the first column width -->
    <td style="text-align: left; width: {if !$tax_excluded_display}25%{else}35%{/if}">{$order_detail.product_name}{if isset($order_detail.product_reference) && !empty($order_detail.product_reference)} ({l s='Reference:' pdf='true'} {$order_detail.product_reference}){/if}</td>
    ...
    <!-- Add our new column, 10% width -->
    <td style="text-align: right; width: 10%; white-space: nowrap;">
        {$order_detail.tax_rate}
    </td>
    ...
</tr>

我认为正确的方法是覆盖OrderInvoice.php 中的getPriducts((函数

foreach ($products as $row)
{
...
$sql = "SELECT tax.rate FROM ps_tax as tax join `ps_order_detail_tax` on ps_order_detail_tax.id_tax = tax.id_tax WHERE ps_order_detail_tax.id_order_detail = " .(int)$row['id_order_detail'] ;
$result = Db::getInstance()->executeS($sql);
$tmp = $result[0];
if (isset($tmp['rate'])){
            $row['tax_rate_product'] = $tmp['rate'];
}
else { //No Tax
$row['tax_rate_product'] = "0.000";
}
...
}

以及.tpl 中的使用率值

...
<td style="text-alig: right; width: 15%">{$order_detail.tax_rate_product}</td>
...

请记住删除cache/class_index.php

也许您有一个取决于发货地址的产品税规则。尝试

foreach ($products as $row)

｛

...
// Retrieve tax rate
$product = new Product($row['product_id']);
$row['tax_rate'] = $product->getTaxesRate(new Address((int)$order->id_address_delivery))
 ...
