[wp-hackers] get_user_meta returning empty string

[Otto]

Actually, if you know the user ID, you'd be better off just using the
WP_User object.

$user = new WP_User($id);

That will retrieve the properties of the user and create an object
with it. However, it also goes and fetches their capabilities for the
current blog as well. You can then use the functionality of the user
object to check for specific capabilities. For example:

if ($user->has_cap('edit_users')) ...

If you just want to see all that user's capabilities, then you can
look at the allcaps array:

var_dump($user->allcaps);

Simple. Works.
