I want to inject Model into core block module. That it's a simple thing to do in the wrong way (Editing core block). But i want to know how to do it in the right way. Because i want to retrieve User data in the main page.

So, how can i do it, without editing core files?

Im customizing my templates and i want to show users name into the main page, Magento_CatalogWidget/templates/product/widget/content/grid.phtml.

To do that i need to inyect \Magento\Customer\Model\Session, the answer is where?

For now i have into grid.phtml the follwing code :

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

You can inject customer model file into your block using __consturct() function.

public function __construct(
            \Magento\Customer\Model\Session $customerSession
        ) {
            $this->customerSession = $customerSession;

    public function myCustom(){
        if ($this->customerSession->isLoggedIn()) {
            echo $this->customerSession->getCustomer()->getName();
  • Perfect! , i think my problem is how to put my block available to use in index page. And not in my own route.

  • yes you can call function directly inside your template file Dec 8, 2016 at 13:16
  • please let me know if you have query Dec 8, 2016 at 13:20

In Magento 1 you'd get someone's session using:


From there if you want to set a variable you can use:

$session = Mage::getSingleton('core/session')

And to retrieve your variable

  • Thanks! But i am working with Magento 2.

core/session is not present in Magento2. There are these ones:


You need to inject an instance of the session you need in your block. Let's take for example \Magento\Catalog\Model\Session.

protected $catalogSession;
public function __construct(
    \Magento\Catalog\Model\Session $catalogSession,
    $this->catalogSession = $catalogSession;

Then you can use the catalog session inside the class like this:


Hope it helps
