How to Create a WooCommerce Buy One Get One Discount?

Despite having a built-in coupon tool, core WooCommerce doesn’t have the features to create a buy-one-get-one WooCommerce discount.

However, there are multiple ways you can achieve this.

  1. Using custom codes in WooCommerce theme files
  2. Using a coupon plugin for creating buy one get one free WooCommerce coupons
  3. Using a premium discount plugin

Let’s check out how to do buy one get one free on WooCommerce using custom codes.

Creating WooCommerce Buy One Get One Discount using Custom Codes

Do not attempt this method unless you are absolutely sure what you are doing. Make sure you are using a child theme or have a backup of your website files.

Let’s create some WooCommerce buy one get one discounts for the following scenarios.

  • Buy any one product and get an extra quantity of the same product for free
  • Buy a specific product and get an extra quantity of that for free
  • Buy X amount of a product to get one for free
  • Buy X product and get Y for free

Buy Any One Product and Get an Extra Quantity of the Same Product For Free

Here are the steps to create this WooCommerce coupon buy one get one off discount.

Step 1 – Access Theme File

Go to Appearance >> Theme File Editor.

theme file editor

Click on the functions.php file and scroll down to the bottom to enter your custom codes.

functions php
Step 2 – Add Custom Code

Create a function to add free quantity –

  • Check Cart Items:
    • Loop through each item in the cart to identify products and their quantities.
  • Add Free Quantity:
    • For each product, if there is at least one quantity, add an equal quantity of the same product for free.

Here are the codes –

function add_bogo_free_product() {

$cart = WC()->cart->get_cart();

// Loop through cart items to check products

foreach ($cart as $cart_item_key => $cart_item) {

     $product_id = $cart_item['product_id'];

     $quantity = $cart_item['quantity'];

     // Ensure no free items are added

     if (!isset($cart_item['custom_price']) && $quantity > 0) {

         // Check if a free product is already in the cart

         $free_product_exists = false;

         foreach ($cart as $free_cart_item_key => $free_cart_item) {

             if ($free_cart_item['product_id'] == $product_id && isset($free_cart_item['custom_price'])) {

                 $free_product_exists = true;

                 break;

             }

         }

         // Add free products if not already in the cart

         if (!$free_product_exists) {

             WC()->cart->add_to_cart($product_id, $quantity, 0, array(), array('custom_price' => 0));

         }

     }

}

}

add_action('woocommerce_before_calculate_totals', 'add_bogo_free_product');

Create the function to apply the custom price

  1. Set Free Product Price to Zero:
    • Loop through the cart and set the price of any product marked as a free item to zero.

Here are the codes –

function apply_bogo_custom_price($cart_object) {

foreach ($cart_object->get_cart() as $cart_item) {

     if (isset($cart_item['custom_price'])) {

         $cart_item['data']->set_price($cart_item['custom_price']);

     }

}

}

add_action('woocommerce_before_calculate_totals', 'apply_bogo_custom_price');
Step 3- Save and Test

Save the functions.php file. Go to your storefront and add any product to the cart.

Go to the cart page, and you will see WooCommerce automatically added an additional quantity of that same product for free.

WooCommerce buy one get one discount

Buy a Specific Product and Get an Extra Quantity of That For Free

Remove the previous code from functions.php and proceed to the following steps.

Add a Function to Add Free Quantity of a Specific Product

Check Cart Items:

  • Loop through the cart items to identify the targeted product and its quantity.

Add Free Quantity:

  • If the targeted product is in the cart, add an equal quantity of the same product for free if not already added.

Here’s the code –

function add_free_product_with_targeted_product() {

// Define the targeted product ID

$targeted_product_id = 123; // Change this to your targeted product ID

// Get the cart items

$cart = WC()->cart->get_cart();

// Initialize flag for targeted product

$targeted_product_count = 0;

$free_product_exists = false;

// Loop through cart items to check for targeted product

foreach ($cart as $cart_item) {

     if ($cart_item['product_id'] == $targeted_product_id) {

         if (!isset($cart_item['custom_price'])) {

             $targeted_product_count += $cart_item['quantity'];

         } else {

             $free_product_exists = true;

         }

     }

}

// Add the free product if the targeted product is in the cart and the free product isn't already in the cart

if ($targeted_product_count > 0 && !$free_product_exists) {

     WC()->cart->add_to_cart($targeted_product_id, $targeted_product_count, 0, array(), array('custom_price' => 0));

}

}

add_action('woocommerce_before_calculate_totals', 'add_free_product_with_targeted_product');

You must replace the product ID ($targeted_product_id = 123;) with your targeted valid product ID.

Collect the Product ID

WooCommerce auto-generates and assigns a product ID to each product you create in your website. You can easily collect them from the All Products page.

Go to Products >> All Products. After that, hover over the targeted product to collect the ID.

product id

Replace the ID in the code above (e.g., $targeted_product_id = 83).

replace id
Add a Function to Apply Custom Price
  1. Set Free Product Price to Zero:
    • Loop through the cart and set the price of any product marked as a free item to zero.

Here are the codes –

function apply_custom_price($cart_object) {

foreach ($cart_object->get_cart() as $cart_item) {

     if (isset($cart_item['custom_price'])) {

         $cart_item['data']->set_price($cart_item['custom_price']);

     }

}

}

add_action('woocommerce_before_calculate_totals', 'apply_custom_price');

Save your functions.php file and test it out from the front end.

We targeted this product –

add product

Let’s add this to the cart and view the cart page.

WooCommerce buy one get one discount

As you can see, WooCommerce automatically added an additional amount of that product for free.

Buy X Amount of a Product to Get One For Free – WooCommerce Buy One Get One Discount

Let’s say you want to offer a WooCommerce BOGO offer where customers need to add 2 items of a targeted product to get one for free.

Here’s the code –

function add_free_product_for_buy_two_get_one($cart) {

// Define the targeted product ID

$targeted_product_id = 123; // Change this to your targeted product ID

// Initialize counts

$targeted_product_count = 0;

$free_product_count = 0;

// Loop through cart items to count quantities

foreach ($cart->get_cart() as $cart_item_key => $cart_item) {

     if ($cart_item['product_id'] == $targeted_product_id) {

         if (isset($cart_item['custom_price'])) {

             $free_product_count += $cart_item['quantity'];

         } else {

             $targeted_product_count += $cart_item['quantity'];

        }

     }

}

// Calculate the required free quantity

$required_free_quantity = floor($targeted_product_count / 2);

// Add free products if needed

if ($required_free_quantity > $free_product_count) {

     $additional_free_quantity = $required_free_quantity - $free_product_count;

     WC()->cart->add_to_cart($targeted_product_id, $additional_free_quantity, 0, array(), array('custom_price' => 0));

}

}

add_action('woocommerce_before_calculate_totals', 'add_free_product_for_buy_two_get_one');

Again, you must replace the product ID with a valid one. Let’s target a different product this time.

collect id

Next, add a function to apply the custom price.

function apply_free_product_custom_price($cart_object) {

foreach ($cart_object->get_cart() as $cart_item) {

     if (isset($cart_item['custom_price'])) {

         $cart_item['data']->set_price($cart_item['custom_price']);

     }

}

}

add_action('woocommerce_before_calculate_totals', 'apply_free_product_custom_price');

Let’s add our targeted product to the cart and jump to the cart page.

add to cart

No WooCommerce buy one get discount applied, right?

no applied

This is because we set the minimum targeted quantity to 2, which means your customers must add 2 quantities of this product to avail themselves of WooCommerce buy two, get one free.

WooCommerce BOGO deal

As you can see, the cart page adds a free product when you increase the quantity to 2.

Buy X Product and Get Y For Free

Let’s say you want to offer a different but specific product for free when the customers adds a targeted product. For instance, we want to offer the previous example’s 44 ID product for free when customers add the 83 ID product to the cart.

Make sure you remove all your previously added codes from the above examples.

Here’s the code for this WooCommerce buy one get one free offer –

function add_free_product_when_targeted_product_in_cart() {

$targeted_product_id = 123; // Change this to your targeted product ID

$free_product_id = 456; // Change this to your free product ID

$cart = WC()->cart->get_cart();

$has_targeted_product = false;

$has_free_product = false;

// Loop through cart items to check for targeted and free products

foreach ($cart as $cart_item) {

     if ($cart_item['product_id'] == $targeted_product_id) {

         $has_targeted_product = true;

     }

     if ($cart_item['product_id'] == $free_product_id && isset($cart_item['custom_price'])) {

         $has_free_product = true;

     }

}

// Add the free product if the targeted product is in the cart and the free product isn't already in the cart

if ($has_targeted_product && !$has_free_product) {

     WC()->cart->add_to_cart($free_product_id, 1, 0, array(), array('custom_price' => 0));

}

}

add_action('woocommerce_before_calculate_totals', 'add_free_product_when_targeted_product_in_cart');

You must replace the IDs with your actual IDS.

In our case, it should be –

$targeted_product_id = 83; // Change this to your targeted product ID
$free_product_id = 44; // Change this to your free product ID

Now, apply the custom price –

function apply_custom_price_for_free_product($cart_object) {

foreach ($cart_object->get_cart() as $cart_item) {

     if (isset($cart_item['custom_price'])) {

         $cart_item['data']->set_price($cart_item['custom_price']);

     }

}

}

add_action('woocommerce_before_calculate_totals', 'apply_custom_price_for_free_product');

Go to the 83 IDs product page and add the item to the cart.

WooCommerce buy one get one discount

As you can see, WooCommerce automatically added the ID-44 product for free when the ID-83 product is added to the cart.
