I really wanted to show the current users biography in a page template for wordpress and I was surprised how long it took me to figure out how to do it. This is the recipe that I got to work. I hope that it helps someone else too.
$user_info = get_userdata($current_user->ID); echo $user_info-> user_description ;
Showing the avatar was easier to figure out:
global $current_user; echo get_avatar( $current_user->ID, 200 );
In this 200 refers to the width of the image.
The name I did like this:
global $current_user; get_currentuserinfo(); echo $current_user->display_name . "\n";
Hope you find this useful – I know I’ll be back needing this again.
