Getting all request parameters in Symfony 2

Question

In symfony 2 controllers, every time I want to get a value from post I need to run:

$this->getRequest()->get('value1');
$this->getRequest()->get('value2');

Is there any way to consolidate these into one statement that would return an array? Something like Zend's getParams()?

Answer 1

You can do $this->getRequest()->query->all(); to get all GET params and $this->getRequest()->request->all(); to get all POST params.

So in your case:

$params = $this->getRequest()->request->all();
$params['value1'];
$params['value2'];

For more info about the Request class, see http://api.symfony.com/2.8/Symfony/Component/HttpFoundation/Request.html

Answer 2

With Recent Symfony 2.6+ versions as a best practice Request is passed as an argument with action in that case you won't need to explicitly call $this->getRequest(), but rather call $request->request->all()

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Exception\BadRequestHttpException;
use Symfony\Component\HttpKernel\Exception\NotAcceptableHttpException;
use Symfony\Component\HttpFoundation\RedirectResponse;

    class SampleController extends Controller
    {


        public function indexAction(Request $request) {

           var_dump($request->request->all());
        }

    }

Since you are in a controller, the action method is given a Request parameter.

You can access all POST data with $request->request->all();. This returns a key-value pair array.

When using GET requests you access data using $request->query->all();

Answer 4

For Symfony 3.4, you can access the data for both GET and POST, Like This

Post:

$data = $this->request->request->all();

Get:

$data = $this->request->query->all();

Well, remember this is always PHP, so you could just check for the superglobal variable $_REQUEST
