How to Maximize BOGO Offers by Offering Multiple Free Items in WooCommerce?

This advanced customization combines the power of Buy One Get One (BOGO) offers with the option for customers to grab multiple free items of their choice during the purchase. With easy checkbox selections, customers personalize their shopping experience, ensuring they only claim these bonuses when adding the main item to their cart.

Additionally, it ensures that customers can get access to these free samples only if they add the main product to the cart or else it pops up a notice message.

            $main_product_id = $product->get_id();
            $free_product_ids = array('470', '457', '100'); // Replace with your actual product IDs

            foreach ($free_product_ids as $free_product_id) {
                $free_product = wc_get_product($free_product_id);
                ?>
