If you want this for all future users then hook into the user_register event and update it there. Pull the WP_User using get_userdata and wp_update_user info with the new display name. add_action( ‘user_register’, ‘wpse_20160110_user_register’, 10, 1 ); function wpse_20160110_user_register ( $user_id ) { // get the user data $user_info = get_userdata( $user_id ); // pick … Read more
