How to get the request parameters in Symfony 2?

Question

I am very new to symfony. In other languages like java and others I can use request.getParameter(\'parmeter name\') to get the value.

Is there anything

Answer 1

try

$request->request->get('acme_demobundle_usertype')['username']

inspect attribute name of your formular field

Answer 2

If you need getting the value from a select, you can use:

$form->get('nameSelect')->getClientData();

Answer 3

$request = Request::createFromGlobals();
$getParameter = $request->get('getParameter');

Answer 4

As now $this->getRequest() method is deprecated you need to inject Request object into your controller action like this:

public function someAction(Request $request)

after that you can use one of the following.

If you want to fetch POST data from request use following:

$request->request->get('var_name');

but if you want to fetch GET data from request use this:

$request->query->get('var_name');

Answer 5

#www.example/register/admin

  /**
 * @Route("/register/{role}", name="app_register", methods={"GET"})
 */
public function register(Request $request, $role): Response
{
 echo $role ;
 }

Answer 6

Your options:

1. Simple:
   • $request->request->get('param') ($_POST['param']) or
   • $request->query->get('param') ($_GET['param'])
2. Good Symfony forms with all validation, value transormation and form rendering with errors and many other features:
   • http://symfony.com/doc/current/book/forms.html
   • http://symfony.com/doc/current/cookbook/form/index.html
3. Something in between (see example below)

<?php
/**
 * @Route("/customers", name="customers")
 *
 * @param Request $request
 * @return Response
 */
public function index(Request $request)
{
    $optionsResolver = new OptionsResolver();
    $optionsResolver->setDefaults([
        'email' => '',
        'phone' => '',
    ]);
    $filter = $optionsResolver->resolve($request->query->all());

    /** @var CustomerRepository $customerRepository */
    $customerRepository = $this->getDoctrine()->getRepository('AppBundle:Customer');

    /** @var Customer[] $customers */
    $customers = $customerRepository->findFilteredCustomers($filter);

    return $this->render(':customers:index.html.twig', [
        'customers' => $customers,
        'filter' => $filter,
    ]);
}
