How to Use Registry in Magento 2

By Sanjay JethvaUpdated on May 22, 2025 1 min read

Magento registry stores data to memory which is specific to a particular request and for a duration of that request only. The Mage class is instantiated as a singleton object for every request and the instantiated Mage object remains in memory and is accessible in all classes until the request completes and the response is sent.

Magento 2 allows registering global variable that supports the static registry method. But, instead of using  Mage :: register() and Mage::registry() in Magento 1, apply /Magento/Framework/Registry. It accepts the settings and the registry of the restored data. In this tutorial, we will learn to create and use your own custom registry in Magento 2.

Follow the below code to use Registry in Magento 2:

<?php
protected $_registry;

public function __construct(\Magento\Framework\Registry $registry)
{
    $this->_registry = $registry;
}

public function setRegistryVariable()
{
    $this->registry->register('customvar', 'Value');
}

public function getRegistryVariable()
{
    return $this->registry->registry('customvar');
}

public function unsetRegistryVariable()
{
    return $this->registry->unregister('customvar');
}

I hope you readers got a proper guide on how to use registry in Magento 2. 

Happy Coding!
