Yes rrosenthal, i add the the country field and works fine. In my shop the customers can only purchase from Spain, so I manually added the country code when I save extra fields. For other cases, I guess adding the option on the form, validate and save the data in the same way as for other fields should work well.
Yes thanks, I had seen them, but all are for the checkout page
hi! I have a similar problem. Add, valid and register new fields and seems it all works, but I need to debug some things. This is the thread that I have opened (https://wordpress.org/support/topic/how-to-add-custom-fields-in-user-registration-on-the-my-account-page?replies=1) I hope we can help! Regards!
