In this example, some information about the current logged in user is displayed, but only when the user is actually logged in.

$user =& JFactory::getUser();
 
if (!$user->guest) {
  echo 'You are logged in as:<br />';
  echo 'User name: ' . $user->username . '<br />';
  echo 'Real name: ' . $user->name . '<br />';
  echo 'User ID  : ' . $user->id . '<br />';
}

Example 2

In this example, information about a specific user, with username 'joebloggs', is displayed, regardless of the status of the current user.

$user =& JFactory::getUser( 'joebloggs' );
 
if ($user->id == 0) {
  echo 'There is no user joebloggs registered on this site.<br />';
} else {
  echo 'User name: ' . $user->username . '<br />';
  echo 'Real name: ' . $user->name . '<br />';
  echo 'User ID  : ' . $user->id . '<br />';
}

In this example, a check is made to determine if the current user has edit permission on content. For more information on permissions see JAuthorization. See also JFactory->getACL.
