What is the proper way to handle errors when setting up a payment method in WooCommerce via PHP?

When setting up a payment method in WooCommerce via PHP, it is important to properly handle errors to provide a smooth user experience. Here are some best practices for handling errors when setting up a payment method in WooCommerce via PHP:

  1. Use try-catch blocks: Wrap the code that sets up the payment method in a try-catch block to catch any exceptions that may occur during the process.
  2. Log errors: Use logging functions such as error_log() or WooCommerce logging system to log any errors that occur during the setup process. This will help you troubleshoot and debug issues more easily.
  3. Display error messages: If an error occurs during the setup process, display a friendly error message to the user to inform them of the issue. This can help prevent confusion and frustration.
  4. Validate input data: Make sure to validate any input data before using it in your code to prevent unexpected errors. For example, check if all required fields are filled out and if the data is in the correct format.
  5. Handle specific error cases: Depending on the type of error that occurs, handle it appropriately. For example, if the payment provider API returns an error code, you can display a specific error message to the user or take specific actions to resolve the issue.


By following these best practices, you can ensure a more robust and reliable payment method setup process in WooCommerce via PHP.

    if ( is_user_logged_in() && in_array( 'customer_role', $current_user->roles ) ) {
        // Add your payment method id here
        $payment_gateway_id = 'your_custom_payment_gateway_id';

        // Enable the payment gateway for the specific user role
        $available_gateways[ $payment_gateway_id ] = WC()->payment_gateways->payment_gateways[ $payment_gateway_id ];
