Email -> Username & Display name -> Nickname

[deniscgn]

Hello,
I need the following, but something is wrong.
The Email should become the User_Login. This works fine.

In my registration I ask for the Display_Name.
This should become the Nickname.

When I use the code I get this WARNINGS:

Warning: Missing argument 2 for update_user_meta(),

/* Email as Username during registration */

function user_meta_pre_user_register_function( $userData ){

	$userData[ 'user_login' ] = $_POST['user_email'];
	return $userData;

	}

add_filter( 'user_meta_pre_user_register', 'user_meta_pre_user_register_function' );

/* Display_name as Nickname after registration */

function user_meta_after_user_register_function( $response ){
	$userID = $response->ID;
	$user_nickname = $_POST['display_name'];
	update_user_meta( array ( 'ID' => $userID, 'nickname' => $user_nickname ) );
}
add_action( 'user_meta_after_user_register', 'user_meta_after_user_register_function' );
