Display order customer note in Woocommerce email notifications - php

Question

In Woocommerce, I am trying to get the customers additional order message:
I am trying to display that customer message on the email notifications.
But i don't know how to get this information in the php code.
Here is my code in the functions.php file:
add_action( 'woocommerce_email_after_order_table', 'ts_email_after_order_table', 10, 4 );
function ts_email_after_order_table( $item_id, $item, $order, $plain_text){
$notes=$order->customer_message; //did not work
echo '<table cellspacing="0" cellpadding="0" style="width: 100%; color: #636363; border: 1px solid #e5e5e5;" border="0"><tbody><tr><td><p>Test: ' . $notes . '</p></td></tr></tbody></table>';
}
I really don't know how to access that information.
Any help is appreciated.

Answer 1

There are some errors in your code. Using the WC_Order method get_customer_note(), try the following instead, that will display for some successful email notifications, the customer order note:
add_action( 'woocommerce_email_after_order_table', 'customer_note_email_after_order_table', 10, 4 );
function customer_note_email_after_order_table( $order, $sent_to_admin, $plain_text, $email ){
// Only on some email notifications
if ( in_array( $email->id, array('new_order', 'customer_on_hold_order', 'customer_processing_order', 'customer_completed_order') ) ) :
// Get customer Order note
$customer_note = $order->get_customer_note();
// Display the Customer order notes section
echo '<h2>' . __("Order notes", "woocommerce") . '</h2>
<div style="margin-bottom: 40px;">
<table cellspacing="0" cellpadding="0" style="width: 100%; color: #636363; border: 2px solid #e5e5e5;" border="0">
<tr><td><p>' . $customer_note . '</p></td></tr>
</table></div>';
endif;
}
Code goes in function.php file of your active child theme (active theme). Tested and works.
