Php Opencart 2.3-在特色扩展中显示折扣

我是Opencart的新手，我试图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

quantity

和

price

从控制器文件

featured.php

传递到视图文件

featured.tpl

以下是我尝试过的：

1） 在文件

/catalog/controller/extension/module/featured.php中
$product\u info=$this->model\u catalog\u product->getProduct（$product\u id）后面的
中我添加了以下代码：

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

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

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

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

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

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

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

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

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

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

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





任何帮助都将不胜感激

我尝试了其他几种代码变体（例如提供的解决方案），但没有成功。
