Bug with one product data for all products in the hook when cache is on

[[email protected]]

Hello to all.

BEFORE

i made module, showing at hook displayProductListReviews (i.e. in the product list in each product) the quantity in cart, with buttons + - on js. Developed, of course with cache disabled, it works, on all pages where there is a hook, lightly tested, everything is OK. But as soon as turned on the cache, then immediately went bugs on the main page in the modules "new", "featured", and "pricedrops".

WHAT I FIND

1) on main page there are not output variables to javascript, unlike the other pages, while the store itself does not suffer, but the module has nothing.

2) when the cache is ON in the modules"new", "featured", and "pricedrops" through the hook displayProductListReviews in the template product-lis.in tpl the variable $product for each product comes one same product data (first in DB response), i.e. the same ID, etc. How can it be I'll never know, because the products themselves are different, and after the hook comes out the same for everyone. If you disable the cache - all OK, each product come as expected their data.

Can't understand this is a Presta bug? or I didn't consider how hooks working with cache?

If I didn't check the cache, then how to do it?
The issue is on default version the Presta (others as well), so all module files have a default code.

Help, please.

 

 

public function hookDisplayProductListReviews($params)
{
        $cart = $this->context->cart;
        $in_cart_count_total = Cart::getNbProducts((int)$this->context->cart->id);
        $id_product = (int)$params['product']['id_product'];
        $product_in_cart_count = $this->productInCartCount($id_product);
        $send_arr = array(
            'product_2' => $params['product'],
            'product_in_cart' => $this->getProductFromCart($id_product),
            'in_cart_count' => $product_in_cart_count,
            'id_customization' => (int)Tools::getValue('id_customization'),
            'priceDisplay' => 1,
            'currency' => $this->context->currency
        );
}

$this->smarty->assign($send_arr);
        return $this->display(__FILE__, 'incartquantity.tpl', null, null);
}

 

incartquantity.tpl code:
