Opencart 2.3 - showing discount in featured extension

Question

I am new to Opencart and I am trying to display the quantity discount in the featured products - without success. I am using Opencart 2.3. Basically, what I would like to achieve is to pass the variables quantity and price from the controller file featured.php to the view file featured.tpl .

Here is what I have tried:

1) In the file /catalog/controller/extension/module/featured.php after the $product_info = $this->model_catalog_product->getProduct($product_id); I added the following code:

$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) In the file /catalog/view/theme/default/template/extension/module/featured.tpl I added the following code:

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

Any help would be very much appreciated!

I have tried several other variations of code (eg the solution provided here ), but no success.

Go to catalog\\language\\en-gb\\extension\\module\\featured.php Add following code:

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

Go to catalog\\controller\\extension\\module\\featured.php Find following lines of code:

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

Add following lines of code:

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

Find following lines of code:

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

Add following lines of code:

$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'])
                );
            }

Find following lines of code:

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

Just below it Add following lines of code:

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

Now go to catalog\\view\\theme\\YOUR_ACTIVE_THEME\\template\\extension\\module\\featured.tpl

Find following lines of code:

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

Add above it or where ever you want to show but need to inside the product array:

<?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 } ?>
