Joomla Direct Logout Link

Joomla Direct Logout Link

#Since I have a habit of forgetting things, I'll keep this here:

The following link is for direct logout:

http://example.com/index.php?option=com_users&task=user.logout
But a user token is required in order to avoid an error message Invalid Token, and some PHP magic is required in order to get the token. The following code will display a Login link to guests, and a direct Logout Username link to logged in users:

$user = JFactory::getUser();
if ($user->guest)
{
    echo '<a href="index.php?option=com_users&view=login">Login</a>';
}
else
{
    $userToken = JSession::getFormToken();
    echo '<a href="index.php?option=com_users&task=user.logout&' . $userToken . '=1">Logout '  . $user->username . '</a>.';
}
