User logged in or not checking not works in other pages such as Product, Category and other static pages but its works well on customer pages like Dashboard, Address book, Orders etc...

Here is my helper: app/code/MyVendor/MyUserModule/Helper/Data.php

        namespace MyVendor\MyUserModule\Helper;
        class Data extends \Magento\Framework\App\Helper\AbstractHelper

            public function __construct(
                \Magento\Framework\App\Helper\Context $context,
                \Magento\Customer\Model\Session $customerSession
            ) {
                $this->customerSession = $customerSession;

            public function isLoggedIn()
                return $this->customerSession->isLoggedIn();
            public function userLoggedDetails()
                return $this->customerSession->getCustomer();

And phtml like this

    $customerSession = $this->helper('MyVendor\MyUserModule\Helper\Data');
    if($customerSession->isLoggedIn()) {
        echo "Welcome ".$customerSession->userLoggedDetails()->getName();
        echo "Login";

Also I noticed logged in or not checking works well on all pages while call ObjectManager directly, like this way

$om = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $om->create('Magento\Customer\Model\Session');

but this method not recommended by experts, so should follow Constructor injecting proper method, Anyone know what I missed, please.

Finally I got the answer, the problem with block cache, to get real Magento session, specific block cache must be false!

I did following changes and worked well:

  1. Added $this->_isScopePrivate = true; in my __construct
  2. Added attribute cacheable="false" to my block which belongs-to my template .phtml
  • Where you add the cacheable="false" ? I have same issue with Magento 2.1 but I do not know where to add attribute and how should look complete file. Commented Apr 4, 2017 at 18:44

    @GeorgeGeorge add cacheable="false" in your layout xml for the curresponding block. In my case on this file, /app/design/frontend/My_vendor/my_theme/Magento_Theme/layout/default.xml I have to add this block <block class="Magento\Framework\View\Element\Template" name="usermenu.us.li" template="Magento_Theme::html/user_nav_us_li.phtml" before="-" cacheable="false"/> Commented Apr 6, 2017 at 7:00
