New field in email

Hi, I pass you the code that I have in the request-quote-form.php file. If I put the code you sent me in the other post it doesn’t show the nicename field. Could you tell me what is wrong?

<?php
/**

$current_user = array();
if ( is_user_logged_in() ) {
$current_user = get_user_by( ‘id’, get_current_user_id() );
}
$user_nicename = ( ! empty( $current_user ) ) ? $current_user->user_nicename : ”;
$user_name = ( ! empty( $current_user ) ) ? $current_user->display_name : ”;
$user_email = ( ! empty( $current_user ) ) ? $current_user->user_email : ”;
