Magento 2: Get Admin session in frontend

Question

How can i get the admin session in frontend.

   $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
   $adminSession = $objectManager->create('Magento\Security\Model\AdminSessionsManager');
   print_r($adminSession->getCurrentSession()->getStatus());

I tried with above script but no luck!

Answer 1

Here you want to get admin session data into the frontend. Both areas are different so we can not get admin current admin login session. For more about area click here. I give you the solution for it.

Try This Code

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'VendoreName_ModuleName',

);

<?php

namespace VendoreName\ModuleName\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper

    public function __construct(

    }

    public function getActiveAdmin()
    {
        return $this->registry->registry('active_admins');
    }
}

When the admin is login then its status is going to active and if he/she sign out then its status goes to inactive. and also if the admin user is login and does not have any activity by admin then its status goes to inactive. In the Observer GetActiveAdminStatus.php file you can set your time what you want

Answer 2

events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="backend_auth_user_login_success">
        <observer name="name_of_observer_for_backend_auth_user_login_success" instance="\Instance\Class\Name" />
    </event>

Then create the observer.

class BackendAuthUserLoginSuccess implements ObserverInterface
{
    const DEFAULT_SESSION_NAME_OF_FRONTEND = 'PHPSESSID';

    /**
     * (non-PHPdoc)
     * @see \Magento\Framework\Event\ObserverInterface::execute()
     */
    public function execute(\Magento\Framework\Event\Observer $observer) {
        if (! isset($_COOKIE[self::DEFAULT_SESSION_NAME_OF_FRONTEND])) return;
        $backSessionId = session_id();
        $frontendSessionId = $_COOKIE[self::DEFAULT_SESSION_NAME_OF_FRONTEND];
        session_write_close();
        session_id($frontendSessionId);
        session_start();
        $_SESSION['admin'] = [$backSessionId];
        session_write_close();
        session_id($backSessionId);
        session_start();
        return;
    }
}
</config>

Answer 3

protected $_session;

public function __construct(
    \Magento\Framework\Model\Context $context,
    \Magento\Backend\Model\Auth\Session $authSession
) {
    $this->_session = $authSession;
    parent::__construct($context);
}

and then call

$this->_session->isLoggedIn()

Note: don't use objectManager directly in the code. Its not proper way to do it in Magento 2.
