How to check if user is logged into the admin [duplicate]

Question

I'm trying to create a script then trigger it from time to time to check "who" is logged in in admin (users), so I created this:

$adminUser = Mage::getModel('admin/user');
$users = $adminUser->getCollection()->load();
echo '<pre>';
foreach($users as $user){
$name = $user->getUsername();
Mage::getSingleton('core/session', array('name'=>$name));
    if(Mage::getSingleton('admin/session')->isLoggedIn()){
        echo $name.' is logged in<br/>';
    }else{
        echo " go away bad boy<br/>";
    }
}
echo '</pre>';

?>

Simplified code .... still no positive results ....

Answer 1

Use below code:

//get the admin session
Mage::getSingleton('core/session', array('name'=>'adminhtml'));

//verify if the user is logged in to the backend
if(Mage::getSingleton('admin/session')->isLoggedIn()){
  //do stuff
}
else
{
  echo "go away bad boy";
}
