    Hello Readers,
    This tutorial will guide you about "How to Set & Retrieve Variable in magento registry ". Registry means creating a new global variable which is to be used later in any magento template file (.phtml). Magento registry function is a static function & can be called directly without creating an object.

     

    There are 3 functions to register, unregister and fetch a registry variable.

     

    register() – This function registers our variables. We can store anything in the registry variable. It can be integer, string, array, etc.

    registry() – This is used to get the value of registered variable.

    unregister() – This function destroys our registered variable.

     

    Set Variable to registry

    Mage::register('name-of-key', $data);


    Retrieve Variable from magento registry.

    $getData = Mage::registry('name-of-key');

     

    Destroy / Unregister the variable

    Mage::unregister('name-of-key');

    This will destroy the variable when we no longer need it.
