How to Add Order Notes in WooCommerce Programmatically?

In this dev blog article, we will look into adding order notes in WooCommerce and also see how can we add and delete an order note manually and programmatically.

WooCommerce order note is a custom message for our future reference or for the customer. It can be added by the admin.

There are two types of order notes.

1. Private note
2. Note for the customer.

1. Private note: When we write some note for a particular order for our future reference but we don’t notify the customer then we add a private note.

2. Note for the customer: When we have to send a note to the customer and notify them then we add a note for the customer.

This is all about the WooCommerce order notes and types of order notes. Now move towards the add order note.

In this section, we will look into how to add order notes manually.

Go to WooCommerce—> Orders —> Click on any order that which you want to add a note.

Here you will see a section of Order Notes on the right-hand side. Add your message in the textarea and select the type of note and click on the add button to add the note for that order.

If you add a note for the customer then the customer will notify through the email.

If you want to delete any of the order notes then simply click on the Delete note link which will appear below the order note as you can see in the above attached image.

In this section, we will look into how to add and delete order notes programmatically.

1. Add Order Note

There are several ways to add notes in the order

$order_note = 'Your order note here';

/**
 * First method to add order note programmatically in woocommerce.
 * Using the <strong>WC_Order </strong>class.
 */
 $order = new WC_Order( $order_id ); 
 $order->add_order_note( $order_note ); // This will add as a private note.
 $order->add_order_note( $order_note, 1 ); //This will add note for the customer.

/**
 * Second method to add order note programmatically in woocommerce.
 * If you don't want to use WC_Order class then you can use
 */
 $order = wc_get_order( $order->get_id() );
 $order->add_order_note( $order_note ); // This will add as a private note.
 $order->add_order_note( $order_note, 1 ); //This will add note for the customer.


/**
 * Third method to add order note programmatically in woocommerce.
 * You can also add order note on hook while creating order note.
 */
 add_action( 'woocommerce_new_order', 'add_custom_order_note',  10, 1  );

    function add_custom_order_note( $order_id ) {
       
       $order = new WC_Order( $order_id ); 
       $order->add_order_note( $order_note ); // This will add as a private note.
       $order->add_order_note( $order_note, 1 ); //This will add note for          the customer.
    }

2. Get all WooCommerce order notes programmatically.

/**
 * Get all order notes of a particular order id.
 *
 * @param int $order_id Order id.
 * 
 * @return array $order_notes All order notes that belogs to the given order id. 
 */
function get_order_notes( $order_id ) {
    remove_filter( 'comments_clauses', array( 'WC_Comments', 'exclude_order_comments' ) );

	$comments = get_comments(
		array(
			'post_id' => $order_id,
			'orderby' => 'comment_ID',
			'order'   => 'DESC',
			'approve' => 'approve',
			'type'    => 'order_note',
		)
	);

	$order_notes = wp_list_pluck( $comments, 'comment_content', 'comment_ID' );

    // You can also use the below code to get notes.
    //$notes = get_comments( $comments )


	foreach ( $order_notes as $key => $note ) {
		$is_customer = get_comment_meta( $key, 'is_customer_note', true );
		$order_notes[ $key ] = array(
            'note_id'    => $key
	        'order_note' => $note,
	        'note_type'  => $is_customer,
		);
	}

	add_filter( 'comments_clauses', array( 'WC_Comments', 'exclude_order_comments' ) );
	
	return $order_notes;
}

Just call the any one above function and pass the order id. It will return the all order notes that belongs to the given order id.

Note – If you have comment_id then you can use wc_get_order_note( $comment_id ) to retrieve the order note.

Delete Order Notes.

/**
 * Here is the code to delete the order note.
 *
 * wp_delete_comment is the core function of wordpress.
 */
wp_delete_comment( $comment_id );

// If you want to do something after the delete the comment then you can add your action on the below do action hook.

do_action( ‘delete_comment’, string $comment_id, WP_Comment $comment )
