Email notification for custom order status

Ok, this is not a complete solution but might help a bit – you can trigger Woocommerce emails like this: WC()->mailer()->emails['WC_Email_Customer_Processing_Order']->trigger($orderId);

Yes, I will try to 🙂
The code you mention in the opening post, where exactly in which file is it located?

Sorry, took bit longer..
Please add this also to your “functions.php” of your active theme:

function my_awesome_shipping_notification( $order_id, $checkout=null ) {
   global $woocommerce;

   $order = new WC_Order( $order_id );

   //error_log( $order->status );

   if($order->status === 'shipping-progress' ) {

      // Create a mailer
      $mailer 		= $woocommerce->mailer();

      $message_body = __( 'Your order is being shipped..', 'text_domain'  );

      $message 		= $mailer->wrap_message(
        // Message head and message body.
        sprintf( __( 'Order %s ready for shipping', 'text_domain'  ), $order->get_order_number() ), $message_body );

      // Client email, email subject and message.
		$result = $mailer->send( $order->billing_email, sprintf( __( 'Order %s received', 'text_domain'  ), $order->get_order_number() ), $message );

	 //error_log( $result );
	}

}
add_action( 'woocommerce_order_status_changed', 'my_awesome_shipping_notification');

If that is the most recommended code for the most recent Woocommerce version I’m not sure. But when I tried it out I received an email when order status was set on “Shipping”, so it worked for me.*

Btw since checking if mailer is really working is a bit tricky:
Add this to wp-config.php

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

The output of error_log( $variable ) will then appear in your-install.com/wp-content/debug.log If you test on localhost like Xampp or WAMP use plugin WP-Mail-SMTP and connect to e.g. to a Google mail account.

Glad to hear 🙂
Btw just to mention, there is a down-side with adding code additions to functions.php of theme. Theme update => additions gone(very likely).
Would be best to put extra code into custom plugin, or https://wordpress.org/plugins/code-snippets/

Thanks a lot for your help, it really saved me.

I created a custom status “was shipped” and the mail is going out.

At the same time I would like to use the functionality of another plugin that appends the tracking info to the outbound mail automaticaly.

The plugin uses the hook “woocommerce_email_before_order_table“.

How can I include the hook or just use the custom mail template alltogether.
Do you happen to know if it is possible to assign the template somehow in the mailer process?

I saw something like

$this->template_html  = 'emails/customer-tracking.php';
$this->template_plain = 'emails/plain/customer-tracking.php';

but it was used in a public function __construct() {}

thanks a lot in advance
