Apply a discount on payment methods in WooCommerce

Apply a discount on payment methods in WooCommerce

In WooCommerce, you can apply discounts to payment methods using specific plugins or through custom code. Here I'll show you how to do it using custom code in your active theme or in a custom plugin. Make sure you have a backup of your site before making changes to the code.

The basic idea is to add a discount to the order total based on the payment method selected by the customer. To do so, follow these steps:

1. Create a child theme (optional but recommended): If you don't already have a child theme, it's good practice to create one to avoid losing customizations when updating the parent theme.
2. Access the child theme files: Use an FTP client or your hosting's file manager to access the child theme files.
3. Open the file functions.php from the child theme: In this file, you will add the code necessary to apply the discount based on the payment method.
4. Add the code to apply the discount: Here is an example of what the code could look like:

// Apply discount based on payment method function apply_discount_by_payment_method($cart) { if (is_admin() && !defined('DOING_AJAX')) return; // Get the current payment method $payment_method = WC()->session->get('chosen_payment_method'); // Define the discount percentage for each payment method $discounts_by_method = array( 'paypal' => 10, // Example: 10% discount for PayPal 'stripe' => 5 // Example: 5% discount for Stripe ); // Apply the discount if the payment method has a defined discount if (isset($discounts_by_method[$payment_method])) { $discount = $cart->get_subtotal() * ($discounts_by_method[$payment_method] / 100); $cart->add_fee('Discount by payment method', -$discount); } } add_action('woocommerce_cart_calculate_fees', 'apply_discount_by_payment_method');

5. Save changes: Upload the file functions.php modified to your child theme folder.

After adding this code, discounts will be automatically applied based on the payment method selected by the customer in the shopping cart. Be sure to customize payment methods and discount percentages to your needs.

Remember that tinkering with the code can have implications for the security and performance of your site, so be sure to thoroughly test in a development environment before applying changes to your live site. If you are not comfortable manipulating code, you can also consider using WooCommerce plugins that offer this functionality.
