Woocommerce Refund Email - php

Question

I have done a vast amount of searching and although I have found users that have asked how to achieve the following no examples of working solutions to the best of my knowledge exist.
The question is regarding the very popular Wordpress plugin "Woocommerce". The plugin comes with an email system to make life easier for the ecommerce site owner and the customer. One issue is that there is no email that is sent when a shop manager changes the order status to "Refunded". Someone has said this is because it is a manual process. This is true it is a process that the shop owner would do via there merchant account or paypal account. But once this is done and the shop owner then logs into their wordpress admin panel and changes an order status to Refunded it would be beneficial for an email to be generated and sent the customer.
This is something I've seen requested.
So I decided to modify a tutorial over at
http://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/#comment-553147
I am trying to have an email sent out when an orders order status is updated to "Refunded".
Here is the code to the initial plugin file
<?php

These are the only 2 files in my plugin. I have activated it and it appears as an email in the list of emails in the woo commerce email tab. Unfortunately no email is sent when the order status is updated.
Can anyone advise why this is failing to work?
I have had some feedback of an individual who said the following
"the actions that you're adding the trigger to are for pending/failed to processing order status changes - http://cld.wthms.co/cZzw
You'd want these to be actions that are related to the refunded orders, like: add_action( 'woocommerce_order_status_refunded', array( $this, 'trigger' ) ); (for the exact one look around woocommerce's email classes)"
I am using Woocommerce 2.1.12

Answer 1

The main problem is that the woocommerce_order_status_refunded hook is not registered by default with the send_transactional_email callback, so you can't use the above method to send emails automatically when the order status is changed to Refunded.
You can change that with the following:
/**
* Register the "woocommerce_order_status_refunded" hook which is necessary to
* allow automatic email notifications when the order is changed to refunded.
*
* #see http://stackoverflow.com/a/26413223/2078474
*/
add_action( 'woocommerce_init', function() {
add_action(
'woocommerce_order_status_refunded',
array( WC(), 'send_transactional_email' ),
10,
10
);
});
Also make sure that you have enable it in the corresponding section in the Woo Settings -> Emails tab:
By default the following actions are registered for automatic email notifications:
woocommerce_low_stock
woocommerce_no_stock
woocommerce_product_on_backorder
woocommerce_order_status_pending_to_processing
woocommerce_order_status_pending_to_completed
woocommerce_order_status_pending_to_on-hold
woocommerce_order_status_failed_to_processing
woocommerce_order_status_failed_to_completed
woocommerce_order_status_completed
woocommerce_new_customer_note
woocommerce_created_customer
Update:
Good news, #helgatheviking just got her WooCommerce pull request merged (see the comments below).
This means we should be able to use the new woocommerce_email_actions filter:
add_filter( 'woocommerce_email_actions', function( $email_actions ) {
$email_actions[] = 'woocommerce_order_status_refunded';
return $email_actions;
});
in WooCommerce 2.3+.
Similar should work for other non-default email actions, like woocommerce_order_status_cancelled.

Answer 2

I think the problem is you are calling
add_action( 'woocommerce_order_status_pending_to_processing_notification', array( $this, 'trigger' ) );
Try calling:
add_action( 'woocommerce_order_status_refunded', array( $this, 'trigger' ) );
