   An Example

   function wpdocs_use_email_as_username( $user_email ) {
   	return $_POST['user_login'];
   }
   
   add_filter( 'user_registration_email', 'wpdocs_use_email_as_username' );

   • This overrides the registration email address entered and changes to the registration username. The intention is to use the registration email address as the username, but there does not appear to be a filter for that. Additionally, register_new_user() may be called without form submission, so the use of $_POST would present problems in that context.
