在Opencart 2.3的首页检测Admin

For whole day I'm trying to find a way to detect that you are logged as Admin in backend while you are displaying the front page. ( Opencart v 2.3 ). Non of advices that i have found today works.. Is there any way to do that? It would be great if there was a function like in Wordpress is_admin()..

You should be in same browser. Now go to any controller and insert the code to check if user_id is set in the session. For example: Go to catalog/controller/common/header.php

Inside the index() method add following code:

    if($this->session->data['user_id']){
        echo 'Admin is logged in';
    }else{
        echo 'Admin is not logged in';
    }

Another way initialize the user object and check with isLogged() method

    $loggeduser = new Cart\User($this->registry);
    if($loggeduser->isLogged()){
        echo "Admin is in";
    }else{
        echo "Admin not in";
    }
