We already saw how to hide Order Notes on the WooCommerce checkout page. This time around, however, our goal is to “move” them – and specifically remove them from their default position (under the shipping form) and add them back under the billing form.
As you can imagine, this is a combo snippet: (1) we remove them (and we’ll use the snippet as per the link above) and (2) we create a new billing field. Finally, (3) we also need to “save” this new field value into the original order notes custom field meta.
If this is difficult to understand don’t worry – just copy/paste the snippet into your functions.php and see magic happen. Enjoy!
