(WordPress) Generate post title from custom field

I had a custom post type that only used custom fields, so I needed to generate a post title from there.
Here’s one way. You can if course chain as many if else as you want to check other types.

functions.php

function custom_post_type_title($post_id)
{
    global $wpdb;
    if (get_post_type($post_id) == 'staff') {
        $name = get_post_custom_values('name');
        $title = $name[0];
        $where = array('ID' => $post_id);
        $wpdb->update($wpdb->posts, array('post_title' => $title), $where);
    } 
}

add_action('save_post', 'custom_post_type_title');
