Extra User Details is the simple plugin that allows you to add extra fields to the user profile page (e.g. Facebook, Twitter, LinkedIn links etc).
Extra fields can be easily accessed in your templates like a general wordpress author details:
<pre><code><?php the_author_meta('meta_key'); ?>
</code></pre>
Plugin saves fields data in wp_usermeta table. You can add and edit extra fields at plugin options section in backend.

Extra User Details

Took me a bit to get this out, since there is no help online.
I wrote a little function and pasted it into my functions.php:
function extra_user_info() {
		global $current_user;
			get_currentuserinfo();

		echo 'Your extra user info is' . $current_user->PUT_YOU_ID_HERE ;      		

	}

add_action ('NAME_OF_HOOK_WHERE_YOU_WANT_IT', 'extra_user_info', 20);


How to display the correct values in the frontend
