在WooCommerce中添加来自其他脚本的客户备注

Question

I have a script that changes the status of orders based on our ERP system.

In addition to that, we need to add customer notes. I found the way to do it:

$order->add_order_note($note);
$order->save();

Unfortunately this won't work outside the order edit screen, I tried to run it from my custom plugin. (source)

If I do it via $order->update_status($status, $note); it only updates the status.

Is there a way to add a note outside the edit screen? (Including e-mailing the customer)

Answer 1

If the note is for the customer (and has to be visible for him) you need to use instead the WC_Order method set_customer_note() (or both):

$order->set_customer_note($note);
// $order->add_order_note($note);
$order->save();

Or:

$order->set_customer_note($note);
$order->update_status($status, $note);

This need to be done before saving the order data or updating the order status.

To re-send the email notification to the customer (if needed) you can use from the current order ID:

$emails = WC()->mailer()->get_emails();

$emails['WC_Email_Customer_Completed_Order']->trigger( $order_id );
// OR: $emails['WC_Email_Customer_Processing_Order']->trigger( $order_id );
