Unfortunately, some functions that are standard in other store systems are still missing in WooCommerce. However, due to the scalability of the system, ways can be found to make these changes later.
The following code takes care of several things at once. Firstly, it can be used to implement a registration for the customer on the My Account login page, as well as on the order overview page. In addition, two extra fields are created within the registration, which are also visible to the admin in the backend and also displayed with each order mail to the admin. The code must be added in the function.php of the used theme, best at the end of the file.
