How to check if the customer is logged in or not in Magento 2?

Jun 12th, 2018 3 min to read

There are some functionalities that we want only the logged-in customers to have access to. In order to achieve this, there must be some way to check if a customer is logged in or not.

There are two ways by which you can check if a customer is logged in or not:

1) By using Object Manager

It is always a bad practice to use ObjectManager directly.

Copy Code

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
	$customerSession = $objectManager->get('Magento\Customer\Model\Session');
	if($customerSession->isLoggedIn()) {
	   // customer login action
	}

2) By Injecting Class (Dependency Injection)

As said earlier, it is one of the worst practices to use the ObjectManager directly. Therefore an alternate way to check if a user is logged in or not is by using the following code in any class except the template files:

You first need to inject the following class in your constructor:
/Magento/Customer/Model/Session

Copy Code

protected $_session;

	public function __construct(
	    ...
	    \Magento\Customer\Model\Session $session,
	    ...
	) {
	    ...
	    $this->_session = $session;
	    ...
	}

Then you need to use Magento\Customer\Model\Session::isLoggedIn() to check if the customer is logged in or not.

Copy Code

if ($this->_session->isLoggedIn()) {
	    // Customer is logged in 
	} else {
	    // Customer is not logged in
	}
