Add Free Product When Coupon Code is Applied

This PHP code adds a product to the cart when a coupon code is applied in WooCommerce. in this example, we add a free product with the id of 14646 when coupon 30OFF is applied with a 30% discount.

To create a discount code in WooCommerce that provides a percentage discount and automatically adds a specific product to the cart when the coupon is applied, you can use the coupon functionality native to WooCommerce and custom PHP code.

Here are the steps:

1. Create a Free Product :

• In your WooCommerce dashboard, go to Products > Add New.
• Create a new product that will be offered for free. Set the regular price to 0.

2. Create a Coupon Code :

• Go to WooCommerce > Coupons.
• Click on Add Coupon.

3. Configure the Coupon :

• Set the coupon code (e.g., “30OFF”).
• Set the discount type to Percentage Discount and enter 30 in the amount field.

4. Add Custom Code :

• Using FTP, navigate to your child themes functions file.
• Open the functions.php file of your child theme.
• Add the following code at the end of the file :
• Alternatively, use a code snippets or custom functionality plugin and add the code there instead.

Swap out 14646 with the ID of the free product you created.

5. Save Changes :

Save the changes to your functions.php file.
