Add a hidden field to your register form
Perhaps you may need to add hidden fields to your registration form. To do this you can use hooks:
um_after_register_fields- this hook can add hidden fields to the registration form.
um_registration_set_extra_data- this hook can save hidden field values on the registration form submit.
See a code example below. You can add a code snippet to the file functions.php in the active theme directory. Skip the opening
