How to create a hidden checkout field?

I want to include a link to a profile of the current user who submitted a checkout form.

That is, to place automatically a current user’s author link like this in the hidden field: example.com/author/username

I want to achieve this by adding a hidden field in checkout form. So to get a link I would write something likes this:

<?php

$currentUser = get_current_user_id();

$user = get_user_by( ‘id’, $currentUser );

$userUrl = get_bloginfo(‘home’).’/author/’.$user->user_login;

echo $userUrl;
?>

My question is how can I create this hidden field in checkout form and also how to include this field on order page and emails?

Thanks
