Check if the end user is admin

Question

I've to check whether the end user is admin or not, I've done right (I hope) but it fails to check. Here is what I'm using;

function checked_already($pid,$input)
{
    global $db;
    if ($mybb->user['usergroup'] != "4")
    {
        error_no_permission();
    }
    $query = $db->simple_select("users", "username", "uid='{$input}' OR username='{$input}'");
    $user = $db->fetch_array($query);

    if (!$user['username'])
    {
        echo "Nothing found!!";
        exit;
    }
}

But it fails to check if the end user is admin. :/ No error at all. What is missing here?

Answer 1

You've not used $mybb in global. Try this;

function checked_already($pid,$input)
{
    global $db, $mybb;
    if ($mybb->user['usergroup'] != "4")
    {
        error_no_permission();
    }
    $query = $db->simple_select("users", "username", "uid='{$input}' OR username='{$input}'");
    $user = $db->fetch_array($query);

    if (!$user['username'])
    {
        echo "Nothing found!!";
        exit;
    }
}
