Send an email notification when order status change from pending to cancelled
The good new: Using woocommerce_order_status_pending_to_cancelled
action hook with a custom function hook in it, solve your problem definitively:
add_action('woocommerce_order_status_pending_to_cancelled', 'cancelled_send_an_email_notification', 10, 2 );function cancelled_send_an_email_notification( $order_id, $order ){ // Getting all WC_emails objects $email_notifications = WC()->mailer()->get_emails(); // Sending the email $email_notifications['WC_Email_Cancelled_Order']->trigger( $order_id );}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and perfectly works in WooCommerce 3+ (still work on version 4.8+)
