How to Add BOGO (Buy One Get One) Gifts Based on Order Total Range in WooCommerce?

This customization is really handy when giving discounts based on the ranges of order total. Regular offers usually stick to a fixed total amount which lacks some flexibility. But with this code, it’s almost like having discount tiers. You can now manage promotions between higher-value and low-value products and set criteria for when customers spend a specific amount.

For instance, if a customer’s order total falls between $200 to $300, they might get a low-value product for free. On the other hand, if customers spend between $500 and $1000, they might get a high-value product for free.

add_action('template_redirect', 'ts_add_product_to_cart');

function ts_add_product_to_cart() {
    if (!is_admin()) {
        global $woocommerce;
        $free_product_id_1 = 470; // Product ID for the first range
        $free_product_id_2 = 457; // Product ID for the second range
        $found = false;
        $min_order_total_1 = 200; // Minimum order total needed to add the first free product
        $max_order_total_1 = 300; // Maximum order total needed to add the first free product
        $min_order_total_2 = 500; // Minimum order total needed to add the second free product
        $max_order_total_2 = 1000; // Maximum order total needed to add the second free product

        $order_total = $woocommerce->cart->total;

        // Check if the order total is within the specified range for the first free product
        if ($order_total >= $min_order_total_1 && $order_total <= $max_order_total_1) {
            add_free_product_to_cart($free_product_id_1);
        }

        // Check if the order total is within the specified range for the second free product
        elseif ($order_total >= $min_order_total_2 && $order_total <= $max_order_total_2) {
            add_free_product_to_cart($free_product_id_2);
        }
    }
}

// Function to add a free product to the cart
function add_free_product_to_cart($free_product_id) {
    global $woocommerce;

    // Check if the product is already in the cart
    $found = false;
    if (sizeof($woocommerce->cart->get_cart()) > 0) {
        foreach ($woocommerce->cart->get_cart() as $cart_item_key => $values) {
            $_product = $values['data'];
            if ($_product->get_id() == $free_product_id) {
                $found = true;
            }
        }
        // If the product is not found, add it
        if (!$found) {
            $woocommerce->cart->add_to_cart($free_product_id);
        }
    } else {
        // If no products in cart, add it
        $woocommerce->cart->add_to_cart($free_product_id);
    }
}

Output

If the order total is, for example, $215, the code checks the first range (between $200 and $300), and as it falls within this range the ‘free product 1’ is added to the cart.

If the order total is, for example, $884, the code checks the second range (between $200 and $300) and adds the corresponding ‘free product 2’ that matches this range of order total.

Similar to the above customization, you can also add different free gifts based on the cart total quantity. Checkout our guide on how to add free gift based on selected quantity in WooCommerce.
