Showing the specific price of a customer group on product listing page

[VillanyLeo]

I'm working on a membership for my ecommerce site, where the premium membership subscribers have access to a variety of exclusive discounts on select products. The membership is already working, and the products are selected by setting the specific (discount) price for the membership group. The thing is, I want to show people (even those who are not members) the member discount as well, so that they will subscribe to the program. I already made this feature for the product page by overriding the ProductController the following way:

<?php

class ProductController extends ProductControllerCore
{
    public function initContent()
    {
        parent::initContent();

        // Ensure product object is available
        $product = $this->context->controller->getProduct();
        $full_price = Product::getPriceStatic($product->id, false, null, 6, null, false, false);

        // Initialize a variable to store the specific price for group id 5
        $club_price = null;

        if ($product) {
            // Get specific prices for the product
            $specific_prices = SpecificPrice::getByProductId($product->id);

            if ($specific_prices) {
                foreach ($specific_prices as $specific_price) {
                    if ($specific_price['id_group'] == 5) {
                        $club_price = round($full_price - $specific_price['reduction']);
                        break; // Stop looping once we find the price for group 5
                    }
                }
            }
        }

        // Assign the specific price to the Smarty variable
        $this->context->smarty->assign('club_price', $club_price);
    }
}

It basically takes the reduction value of the products from specific_prices table, where id_group is 5, and subtracts this reduction from the full prices, and the value it displays will be the price I want. The problem is, I want to display this same price for the product listing page as well, and I tried a similar method for CategoryController, but I can't seem to find out why it won't work.

This is how I tried to override my CategoryController:

 

<?php

class CategoryController extends CategoryControllerCore
{
    public function initContent()
    {
        parent::initContent();

        $products = $this->cat_products; // Get the products in the category

        foreach ($products as &$product) {
            $full_price = Product::getPriceStatic($product['id_product'], false, null, 6, null, false, false);
            $club_price = null;

            $specific_prices = SpecificPrice::getByProductId($product['id_product']);

            if ($specific_prices) {
                foreach ($specific_prices as $specific_price) {
                    if ($specific_price['id_group'] == 5) {
                        $club_price = round($full_price $specific_price['reduction']);
                        break;
                    }
                }
            }

            $product['club_price'] = $club_price; // Add club_price to the product array
        }

        $this->context->smarty->assign('products', $products); // Reassign the modified products array
    }
}

Whenever I try to display $product.club_price, it only displays 'Array' on the page. I tried to find the solution for hours, but no success yet.

I think it would be a better option to do it through a module located for example in displayProductPriceBlock.
