How to access route, post, get, server etc parameters from view file in Zend Framework 2

Question

How can we access route, post, get, server parameters from VIEW file in ZF2 way?

Here I found the almost same question but no where mentioned about view nor answered anywhere

Thanks

Answer 1

You have to create a view helper to fetch these parameters for you.

View Helper

Simply copy over the Zend\Mvc\Controller\Plugin\Params to App\View\Helper\Params and make a few adjustments:

<?php

namespace App\View\Helper;

use Zend\Mvc\MvcEvent;
use Zend\Stdlib\RequestInterface;
use Zend\View\Helper\AbstractHelper;

class Params extends AbstractHelper
{
    protected $request;

    protected $event;

    public function __construct(RequestInterface $request, MvcEvent $event)
    {
        $this->request = $request;
        $this->event = $event;
    }

    public function fromPost($param = null, $default = null)
    {
        if ($param === null)
        {
            return $this->request->getPost($param, $default)->toArray();
        }

        return $this->request->getPost($param, $default);
    }

    public function fromRoute($param = null, $default = null)
    {
        if ($param === null)
        {
            return $this->event->getRouteMatch()->getParams();
        }

        return $this->event->getRouteMatch()->getParam($param, $default);
    }
}

Just replace all instances of $controller with the $request and $event properties. You get the idea. (Don't forget to copy over the DocBlock comments!)

Factory

Next we need a factory to create an instance of our view helper. Use something like the following in your App\Module class:

<?php
namespace App;

use App\View\Helper;
use Zend\ServiceManager\ServiceLocatorInterface;

class Module
{
    public function getViewHelperConfig()
    {
        return array(
            'factories' => array(
                'Params' => function (ServiceLocatorInterface $helpers)
                {
                    $services = $helpers->getServiceLocator();
                    $app = $services->get('Application');
                    return new Helper\Params($app->getRequest(), $app->getMvcEvent());
                }
            ),
        );
    }
}

How to use

Once you have all this you're in the home stretch. Simply call up the params view helper from within your view:

// views/app/index/index.phtml
<?= $this->params('controller') ?>
<?= $this->params()->fromQuery('wut') ?>

Hope this answers your question! Let me know if you need any clarifications.
