Show and Edit User Meta in Wordpress

Description

This simple procedure will allow you to:

1. Display user meta fields under in the user list as additional columns (Users > All Users).
2. Display these fields on user profiles.
3. Edit these fields under user edit.

This method works completely without plugins and involves just some functions and hooks in functions.php. Plugins like "User Meta Display" achieve this to some level, but treat custom meta fields completely different from the regular fields. They are shown and edited in seperate environment and fail to show the meta data is a table list. This method integrates custom user meta along with regular user (meta).

This extends the built-in WordPress function get_the_ID() to return the post ID both inside and outside the loop.

Used outside the loop (in header.php):

<?php if ( function_exists( 'gt_hide_nav' ) && ! gt_hide_nav() ) : ?>
  <nav role="navigation">
    <?php if ( function_exists( 'bones_main_nav' ) ) bones_main_nav(); ?>
  </nav>
