Implementing a BOGO-tiered pricing strategy in WooCommerce is now easier than ever with this PHP snippet.

Solution: Add BOGO (Buy One Get One) Offers Based on WooCommerce Cart Total Range

The below code snippet will offer different free products based on the pre-defined cart total ranges that help a store owner to implement a tiered pricing strategy. For each spending range, the code automatically adds different free products to the cart. For example:

• Spend between $50 and $100: Get Product A for free.
• Spend between $100 and $200: Get Product A and Product B for free.

function ts_add_products_to_cart() {
    global $woocommerce;

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

    if (!is_admin()) {
        // Define your cart total ranges and corresponding products
        $ranges_and_products = array(
            array('min' => 50, 'max' => 100, 'products' => array(470)),       // For $0 to $100, add Product A
            array('min' => 100, 'max' => 200, 'products' => array(457, 470)), // For $101 to $200, add Product A & Product B
        );

        foreach ($ranges_and_products as $range) {
            $min = $range['min'];
            $max = $range['max'];

            if ($cart_total >= $min && $cart_total <= $max) {
                $products_to_add = $range['products'];

                // Check if the products are already in the cart
                $found_products = array();

                foreach ($products_to_add as $product_id) {
                    foreach (WC()->cart->get_cart() as $cart_item_key => $values) {
                        $_product = $values['data'];
                        if ($_product->get_id() == $product_id) {
                            $found_products[] = $product_id;
                        }
                    }
                }

                // If any product is not found, add it to the cart
                foreach ($products_to_add as $product_id) {
                    if (!in_array($product_id, $found_products)) {
                        WC()->cart->add_to_cart($product_id);
                    }
                }

                // Stop further processing to prevent adding multiple sets of products
                return;
            }
        }
    }
}

add_action('template_redirect', 'ts_add_products_to_cart');

Output

When the customer’s cart total falls with the specified range of $50 to $100, the corresponding free product A is added to the cart.

When the cart total falls in the next specified range of $100-$200, both product A and product B is automatically added to the cart.
