Saving value from wp_dropdown_users as meta?

[notfilc]

I’m familiar with adding custom meta boxes to my post types in WordPress but this is something I’ve not had to do before. I want to be able to select a user from a dropdown (in a metabox) and have that value saved with the post.

Here’s my code:

function add_users_meta_box() {
add_meta_box(
‘users_meta_box’, // $id
‘Assign to user’, // $title
‘show_users_meta_box’, // $callback
‘property’, // $page
‘side’, // $context
‘high’); // $priority
}

add_action(‘add_meta_boxes’, ‘add_users_meta_box’);

function show_users_meta_box() {
wp_dropdown_users(array(‘name’ => ‘author’, ‘show_option_none’ => ‘– None –‘,’selected’ => $user_id));
}
Is it possible to extend this to both save the value and when the user re-opens the post to edit, have the position of the dropdown saved.

If anyone could point me in the right direction it would be much appreciated.
