<?php
use Symfony\Component\HttpFoundation\JsonResponse;

class ReaddToCartModuleFrontController extends ModuleFrontController
{
    public $ajax = true;

    public function initContent()
    {
        parent::initContent();
        
        $productId = Tools::getValue('id_product');
        $quantity = Tools::getValue('qty', 1);

        // Debugging output
        error_log("Product ID: " . $productId);
        error_log("Quantity: " . $quantity);

        if (!$productId || !Validate::isUnsignedId($productId)) {
            error_log("Invalid product ID: " . $productId);
            $this->ajaxDie(json_encode(['success' => false, 'message' => 'Invalid product ID']));
        }

        $cart = $this->context->cart;
        if (!$cart->id) {
            $cart->add();
            $this->context->cookie->id_cart = $cart->id;
        }

        $updateQuantity = $cart->updateQty($quantity, $productId);
        if ($updateQuantity) {
            error_log("Product added to cart successfully");
            $this->ajaxDie(json_encode(['success' => true, 'message' => 'Product added to cart']));
        } else {
            error_log("Failed to add product to cart");
            $this->ajaxDie(json_encode(['success' => false, 'message' => 'Failed to add product to cart']));
        }
    }
}

It can depend on theme and/or cart module. Can you specify theme, PS version, PHP version and cart module used and its configuration.

I'm not using any cart module but the original version PS 1.7, PHP 7.2 . Also is it possible to refresh just the cart and not the whole page? If possible what are the ways we can do that in prestashop?

If you are using the Prestashop base and classic theme, the cart is managed by the module ps_shoppingcart. And you can set it to ajax mode or not.

@Prestashop Addict Add In the title of the topic, it is clearly specified that he wants to use his own module and update the cart.

@dwdsaq2 Find jQuery prestashop.on('updateCart ... or prestashop.emit('updatedCart ....
