Add a custom order note programmatically in Woocommerce admin order edit pages
From a dynamic Order Id you can use WC_Order
add_order_note()
method this way:
// If you don't have the WC_Order object (from a dynamic $order_id)
$order = wc_get_order( $order_id );
// The text for the note
$note = __("This is my note's text…");
// Add the note
$order->add_order_note( $note );
Tested and works.
Thank you guys I was trying to find a way to add the notes to a new order. I was looking for the right hook using the solution that @LoicTheAztec posted. This is the solution that worked for me hope it helps someone else out there.
add this to the Functions.php file
add_action( 'woocommerce_new_order', 'add_engraving_notes', 1, 1 );
function add_engraving_notes( $order_id ) {
//note this line is different
//because I already have the ID from the hook I am using.
$order = new WC_Order( $order_id );
// The text for the note
$note = __("Custom Order Note Here");
// Add the note
$order->add_order_note( $note );
}
