In view helper you have to add code like this:

Module.php

 'factories' => array(
            'myViewHelper' => function($pm) {
                return new MyView($pm);
            },

        )

Now in Helper Class file your have to add following piece of code

public function __construct($pm) {
    $this->pluginManager = $pm;
    $this->serviceLocator = $this->pluginManager->getServiceLocator();
    $this->routeMatch = $this->serviceLocator->get('Router')->match($this->serviceLocator->get('Request'));
}
public function __invoke() {
    $params = $this->getRouteMatch()->getParams();

}

Here $params will return all route params in array formate.

Given the code from the blog post, you can use this code from inside the view helper:

$this->request->getPost('param');  // post parameter

// or

$this->request->getQuery('param'); // query parameter

The code from the example receives an instance of the Zend\Http\Request object for the current request and stores it in the property called request of the view helper so you can use the request property to access the Request object and information from it.
