YiiFramework - Check If User Is Logged In (couponic)

So, I was doing a bit of customization of a Couponic template where I wanted to add a squeeze box (a future post!), but I first needed to check if a user was logged in or not. I didn't want a logged in user to see the squeeze box so I needed to figure out how the framework checked if a user is logged in. Well, it's pretty simple (I've included a quick and dirty write to the browser console log for quick debugging)

 <?php $isUser = Yii::app()->user->checkAccess('user');
  if(!$isUser){ ?>
   <script>
    console.log("NOT A USER!!!!!!!!!!!!");
   </script>
  <?php }else{ ?>
   <script>
    console.log("IS A USER!!!!!!!!!!!!");
   </script> 
  <?php } ?>
