Solution: Add a Free Gift When Any Coupon is Applied in WooCommerce

This code snippet adds a specific product (identified by its ID given in the code) as a free gift to the WooCommerce cart whenever any coupon is applied. It ensures that the free product is only added once per session, preventing duplicates in the cart.

function ts_add_free_product_based_on_coupon() {
    global $woocommerce;

    // Set the ID of the free product
    $free_product_id = 470; // Set the ID of the free product

    // Check if any coupon is applied
    if ($woocommerce->cart->applied_coupons) {

        // Check if the free product is not already in the cart
        $product_already_in_cart = false;
        foreach ($woocommerce->cart->get_cart() as $cart_item) {
            if ($cart_item['product_id'] == $free_product_id) {
                $product_already_in_cart = true;
                break;
            }
        }

        // If the free product is not in the cart, add it
        if (!$product_already_in_cart) {
            $woocommerce->cart->add_to_cart($free_product_id);
            wc_add_notice(__('Free product added!'), 'success');
        }
    }
}
add_action('woocommerce_before_cart_table', 'ts_add_free_product_based_on_coupon', 10, 0);
