Opencart 2.3 - 在特色扩展中显示折扣

Opencart 2.3 - showing discount in featured extension

我是 Opencart 的新手,我想在特色产品中显示数量折扣 - 但没有成功。我正在使用 Opencart 2.3。基本上,我想要实现的是将变量 quantityprice 从控制器文件 featured.php 传递到视图文件 featured.tpl.

这是我尝试过的:

1) 在文件/catalog/controller/extension/module/featured.php$product_info = $this->model_catalog_product->getProduct($product_id);之后添加了如下代码:

$discounts = $this->model_catalog_product->getProductDiscounts($product_id);

$data['discounts'][] = array();

foreach ($discounts as $discount) {
    $data['discounts'][] = array(
'quantity' => $discount['quantity'],
'price' => $discount['price']
);
}

2) 在文件 /catalog/view/theme/default/template/extension/module/featured.tpl 中我添加了以下代码:

<?php foreach ($discounts as $discount) { ?>
<span>
<?php echo sprintf($text_discount, $discount['quantity'], $discount['price']); ?>
</span><br>
<?php } ?>

非常感谢任何帮助!

我尝试了其他几种代码变体(例如提供的解决方案 here),但没有成功。

转到catalog\language\en-gb\extension\module\featured。php 添加以下代码:

$_['text_discount']            = ' or more ';

转到catalog\controller\extension\module\featured。php 查找以下代码行:

$data['heading_title'] = $this->language->get('heading_title');

添加以下代码行:

$data['text_discount'] = $this->language->get('text_discount');

找到以下代码行:

foreach ($products as $product_id) {
   $product_info = $this->model_catalog_product->getProduct($product_id);

添加以下代码行:

$discounts = $this->model_catalog_product->getProductDiscounts($product_id);

            $product_info['discounts'] = array();

            foreach ($discounts as $discount) {
                $product_info['discounts'][] = array(
                    'quantity' => $discount['quantity'],
                    'price'    => $this->currency->format($this->tax->calculate($discount['price'], $product_info['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency'])
                );
            }

找到以下代码行:

$data['products'][] = array(
                    'product_id' => $product_info['product_id'],

在其下方添加以下代码行:

'discounts'=>$product_info['discounts'],

现在去 catalog\view\theme\YOUR_ACTIVE_THEME\template\extension\module\featured.tpl

找到以下代码行:

 <div class="button-group">
            <button type="button" onclick="cart.add('<?php echo $product['product_id']; ?>');">

在其上方或您想要显示但需要在产品数组内的任何位置添加:

<?php if ($product['discounts']) { ?>
        <ul>
            <hr>
            <?php foreach ($product['discounts'] as $discount) { ?>
            <li><?php echo $discount['quantity']; ?><?php echo $text_discount; ?><?php echo $discount['price']; ?></li>
            <?php } ?>
        </ul>
        <?php } ?>
