I want to check if a customer is logged or not. And if he/she logged, I want to get the customerId. I just googled but I could find 2 ways. One is to use CustomerSession: Magento\Customer\Model\Session Another one is to use Customer\Model\Context. Magento\Customer\Model\Context::CONTEXT_AUTH

Which is right way? These 2 articles show different way. I am really confusing what I should use. http://www.blogtreat.com/get-logged-in-customer-data-in-magento-2/

Magento 2: get customer id of logged in user with cache enabled

you can try Following Way..

In Magento 2 we can check Customer is logged in or not by below way, Using Block file, Pass Magento\Framework\App\Http\Context as a dependency to construct method.

 <?php namespace Rakesh\Customer\Block; class Customerinfo extends \Magento\Framework\View\Element\Template { public function __construct( \Magento\Framework\View\Element\Template\Context $context, \Magento\Framework\App\Http\Context $httpContext, array $data = [] ) { $this->httpContext = $httpContext; parent::__construct($context, $data); } /* * return bool */ public function getLogin() { return $this->httpContext->isLoggedIn(); } ?>

Call getLogin function in template file,

$isLoggedin = $block->getLogin(); if($isLoggedin) { // show your message }

You shouldn't use dependency injection into your .phtml files. I'll leave you an example of how to check it in a Helper class.

use Magento\Framework\App\Helper\AbstractHelper; class Data extends AbstractHelper { /** * @var \Magento\Framework\App\Http\Context */ private $httpContext; public function __construct( \Magento\Framework\App\Helper\Context $context, \Magento\Framework\App\Http\Context $httpContext ) { parent::__construct($context); $this->httpContext = $httpContext; } public function isLoggedIn(){ $isLoggedIn = $this->httpContext->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH); return $isLoggedIn; } }

Then you can call this in your phtml in order to obtain the value:

$myhelper = $this->helper('Vendor\Module\Helper\Data'); $isloggedin = $myhelper->isLoggedIn();
