I have a function that retrieves a visiting user's country name by doing an ip lookup. I currently have this function running through the execute method in my module's controller. The problem is that I need this to run on every page and not just the single controller page.

Since every controller is tied to a particular action I am not sure if keeping it in a controller is the correct solution, nor do I know how to run my controller on every page request.

Does anybody know how to do this?

    You should use an observer for this. Connect it to one of the controller dispatch events so it's fired on every front end page request

Per Robbie's suggestion I created:


<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  <event name="controller_action_predispatch">
      <observer name="my_observer" instance="Module\Path\To\MyClass" shared="false" />

Then created observer class


namespace Module\Namespace\Path;

use Magento\Framework\Event\ObserverInterface;

class MyClass implements ObserverInterface
    public function execute(\Magento\Framework\Event\Observer $observer)
       // insert code here


From here I injected the required classes for my function and was able to get everything working. Thanks for pointing me in the right direction.
