How to Execute Code Only Once on Bank Wire Payment Confirmation in WooCommerce

Managing payments in WooCommerce can be a tricky affair, especially when dealing with methods like bank transfers (BACS). In this post, we'll tackle the challenge of executing specific code only once once an order's payment status is confirmed via bank wire.

The Challenge

When a customer chooses bank transfer as their payment method, the store manager is responsible for confirming the payment manually by updating the order status. The issue arises when you want to run some code (for instance, to grant access to digital products or send notifications) only once for each successful transaction. This is particularly relevant for the following status changes:

From On Hold to Processing

From On Hold to Completed

From On Hold to Processing, and then to Completed

Why is this Important?

Since payment confirmations are done manually, it’s crucial to have a mechanism that prevents the same action from running multiple times for the same order. For example, you wouldn’t want an email to be sent or a product to be delivered more than once for a single transaction.

The Solution

WooCommerce provides a suitable hook called woocommerce_order_status_changed that allows you to run a custom function whenever the order status is changed. Here's how you can set it up effectively:

Step-by-Step Guide to Implement

Add the Following Code to your theme's functions.php file (preferably in a child theme) or in a custom plugin:

Breaking Down the Code

The add_action function hooks our custom function bacs_payment_complete to WooCommerce's order status change event.

Inside our function, we first check:

If the payment method is bacs.

If the new status is one of the paid statuses (like Processing or Completed).

If our custom meta (confirmed_paid) is not set to 'yes', indicating we haven't run this code for this order yet.

If all conditions are met, we mark the order as confirmed by updating the metadata and save it to the database.

Finally, at the designated spot, include any code you want to run only once for that order.

Conclusion

By implementing the above solution, you can manage the execution of your code efficiently when handling bank wire payments in WooCommerce. Now you can ensure that critical actions are performed just once, preserving the integrity of your order management process.

Feel free to test this code in your WooCommerce environment and adapt it according to your specific needs!
