Solution: Set Up a BOGO Deal: Spend X More and Get a Free Product

The code will automatically add a free product to the cart when a customer’s cart total spending reaches a specified amount. Additionally, it shows a message to encourage customers to spend a bit more to get the free item.

add_action('woocommerce_before_cart', 'ts_add_notice_and_free_product');

function ts_add_notice_and_free_product() {
    // Set the minimum amount for the free product
    $min_amount_for_free_product = 50; // Adjust this to your desired minimum amount
    $free_product_id = 470; // Replace with the actual product ID of the free product

    $cart_subtotal = WC()->cart->subtotal; // Use subtotal
    $remaining_amount = $min_amount_for_free_product - $cart_subtotal;

    // Set a threshold for displaying the notice 
    $notice_threshold = $min_amount_for_free_product - 5;

    // If the cart subtotal is within the threshold, display the specific notice
    if ($cart_subtotal >= $notice_threshold && $cart_subtotal < $min_amount_for_free_product && $remaining_amount > 0) {
        $notice = sprintf("Spend %s more to get a free product!", wc_price($remaining_amount));
    } elseif ($remaining_amount <= 0) {
        // If the threshold is reached, add the free product to the cart
        $product_to_add = wc_get_product($free_product_id);

        if ($product_to_add) {
            WC()->cart->add_to_cart($free_product_id);
            $added_notice = sprintf("Congratulations! You've earned a free %s. It has been added to your cart.", $product_to_add->get_name());
            wc_print_notice($added_notice, 'success');
        }
    }

    // Display the notice, if it is not empty
    if (!empty($notice)) {
        wc_print_notice($notice, 'notice');
    }
}

Output

If the customer’s cart total falls below the specified minimum amount ($50) required for the free product, and the cart total is close to the threshold amount ($5), the notice will be triggered, prompting the message ‘Spend $5 more to receive a free product.’

When the customer’s cart subtotal has reached the specified minimum amount for free gift, then the free gift will be automatically added to the cart as shown below.

Similarly, you can take this strategy a step further by offering a “Spend $X to unlock free shipping in WooCommerce” as this encourages customers to spend a bit more to benefit from free shipping.
