Magento 2: Check Customer Logged In or Not on Basis of Customer Id

Question

We have below code to check user logged in or not.

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

I already have Customer Id. How to check on basis of that?

Answer 1

1) Inject the online customer collection factory in your constructor

public function __construct(
Magento\Customer\Model\ResourceModel\Online\Grid\CollectionFactory $onlineCustomerCollectionFactory
) {
   $this->onlineCustomerCollectionFactory = $this->onlineCustomerCollectionFactory;
}

2) now create a collection object and apply appropriate filters and load it in your function. Optimize the logic as per your need. I am providing a general code.

public function getOnlineCustomers() {

    $onlineCustomersCollection = $this->onlineCustomerCollectionFactory->create();

    /**
     * this will return all the customers that are online including 
     * registered and non-registered. So apply filters as per your
     * your requirement using addFieldToFilter() function on collection
     */
    $onlineCustomers = $onlineCustomerCollection->load()->getItems();
    return $onlineCustomers;
}
