I'm wanting to utilize the wordpress Display title, however have recognized this appears to become saved by 50 percent places within the DB:

wordpress_customers > display_title

wordpress_usermeta > meta_key (with the need for display_title)

Basically do:

get_currentuserinfo();
echo $current_user->display_name;

or

get_bloginfo( 'name', 'display' )

These both appear to become tugging in the wordpress_usermeta.

Questions:

  1. Exactly why is display title saved in 2 locations?
  2. Where's the area in wordpress_customers utilized in Wordpress?
  3. It is possible to function to reference the main one saved in wordpress_customers (display increase)?
  4. Should i be upgrading the display title, must i be upgrading These two fields?

Thanks!
