[SOLVED] In a theme, how can you check if a user is logged in or is "admin"?

In a theme, how can you check if a user is logged in or is "admin"?

I'm creating a mediawiki theme for my wiki. It is more than just css, I'm changing the layout too, as described in the mediawiki docs.

I would like to make the interface very simple, so I want to only show certain sidebars and other content if a user is logged in or is an "admin" user (or whatever they are called in mediawiki).

Changing the layout is done via php functions that I create in my skins php to output various page elements.

How do you check if a user is logged in? Or what rights/role they have? Is there some kind of function I can check, or constant set by mediawiki?

Solution

I have found the answer, incase anyone else needs it, it is:

$this->getSkin()->getUser()->isLoggedIn()

and with this function you can check if the user is admin:

/**
 * Returns true if user is admin.
 */
protected function userIsAdmin() {
    $isAdmin = FALSE;

    if ($this->getSkin()->getUser()->isLoggedIn() === TRUE) {
        foreach ($this->getSkin()->getUser()->getGroups() as $key => $group) {
            if ($group == 'sysop') {
                $isAdmin = TRUE;

                break;
            }
        }
    }

    return $isAdmin;
}
