I'd like to insert a new field in the user profile in the backend, like another phone number or a website url. The easiest way is to edit directly the class-ac-admin-profile.php file. But a Woocommerce update will overwrite the code. So I'd like to insert this line using my theme directory.
You can paste below code snippet in your active theme's functions.php file or better in child theme's functions.php file.
Thanks Milan, you rock !
