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 similar that we can do with symfony2.
I have seen some examples but none is working for me. Suppose I have a form field with the name username. In the form action I tried to use something like this:

$request = $this->getRequest();
$username= $request->request->get('username');

I have also tried

$username = $request->getParameter('username');

and

$username=$request->request->getParameter('username');

But none of the options is working.However following worked fine:

foreach($request->request->all() as $req){
    print_r($req['username']);
}

Where am I doing wrong in using getParameter() method. Any help will be appreciated.

  • You have a typo in line two: $request->request-get() should be $request->request->get(). Could that be it? Commented Mar 20, 2012 at 11:01
  • have written same in the code.missed out here.sorry for the typo here .still this is not working. Commented Mar 20, 2012 at 12:08
  • Have you (a) checked the manual to ensure that get() is the correct method and (b) turned on PHP notices so you can see if there are any problems? (c) Does Symfony 2 have a debug toolbar like symfony 1, so you can see if you've made any errors? Commented Mar 20, 2012 at 12:31
  • Are you confusing firstname and username? Commented Mar 20, 2012 at 13:09

The naming is not all that intuitive:

use Symfony\Component\HttpFoundation\Request;

public function updateAction(Request $request)
{
    // $_GET parameters
    $request->query->get('name');

    // $_POST parameters
    $request->request->get('name');

    // As of 6.3 Posted or json content
    $request->getPayload()->get('name');

Update Nov 2021: $request->get('name') has been deprecated in 5.4 and will be private as of 6.0. It's usage has been discouraged for quite some time.

Update May 2023: As of 6.3, a getPayload method has been added for post/json data.

It is different from what PHP uses, but it actually makes more sense. $_GET data is data from the query string (no GET request needed at all) and $_POST data is data from the request body (does not have to be a POST request either, could be PUT).
tried $request->query->get('name'); but it is also not working.
How do I get the parameters from a PUT request?
Very strange naming here, surely $request->get and $request->post would be simpler.
comment from igorw brings clarity to this freaky naming convention

I do it even simpler:

use Symfony\Component\HttpFoundation\Request;

public function updateAction(Request $request)
{
    $foo = $request->get('foo');
    $bar = $request->get('bar');
}

Another option is to introduce your parameters into your action function definition:

use Symfony\Component\HttpFoundation\Request;

public function updateAction(Request $request, $foo, $bar)
{
    echo $foo;
    echo $bar;
}

which, then assumes that you defined {foo} and {bar} as part of your URL pattern in your routing.yml file:

acme_myurl:
    pattern:  /acme/news/{foo}/{bar}
    defaults: { _controller: AcmeBundle:Default:getnews }

and in the first example, if I have foo parameter both in query string and in POST body, which one will be returned by $request->get('foo')?
Looks like precedence is GET, PATH, POST api.symfony.com/master/Symfony/Component/HttpFoundation/…
This is the best answer
No it's not. The documentation of the method itself says it is discouraged to use it because it's heavier than accessing the GET/POST parameters through their specific collections.
Answer is correct $request->get('foo'); works for ALL bags (order is : PATH, GET, POST). Nevertheless, $request->request->get('foo'); works only for POST bag. Finally, the first one ($request->get()) is not recommended if we know where the data is (GET/POST).

You can Use The following code to get your form field values

use Symfony\Component\HttpFoundation\Request;

public function updateAction(Request $request)
{
    // retrieve GET and POST variables respectively
    $request->query->get('foo');
    $request->request->get('bar', 'default value if bar does not exist');
}

Or You can also get all the form values as array by using

$request->request->all()

$request->request->all() is working for me but something like $request->query->get('foo'); is not working.

try

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

inspect attribute name of your formular field

+1, since I think that of all the responses, only this one actually states the non-obvious thing - in cases you have created your forms automatically with help of symfony's form builder, symfony renames the form field to something more than you'd expect. Like name="acme_demobundle_userform[field_name]"
Syntax you mentioned here is not working with php 5.3.10. What is minimum version to support that?
@justinasLelys try $userType = $request->request->get('acme_demobundle_usertype'); $username = $userType['username'];
@JustinasLelys Syntax is PHP 5.4
"username" can not be defined. So better check with "??" first.

Inside a controller:

$request = $this->getRequest();
$username = $request->get('username');

In newer versions of Symfony, $this->getRequest() is deprecated, in favour of injecting the Request into the controller action, eg: public function showAction(Request $request, $id);
9

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');

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:
  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,
    ]);
}

You can do it this:

$clientName = $request->request->get('appbundle_client')['clientName'];

Sometimes, when the attributes are protected, you can not have access to get the value for the common method of access:

(POST)

 $clientName = $request->request->get('clientName');

(GET)

$clientName = $request->query->get('clientName');

(GENERIC)

$clientName = $request->get('clientName');

Welcome to Stack Overflow. Please format your answer to make it more readable next time and also check this help page: How to Answer
what if there is 2 value after get ? like this $clientName = $request->query->get('clientName','any');
3

Most of the cases like getting query string or form parameters are covered in answers above.

When working with raw data, like a raw JSON string in the body that you would like to give as an argument to json_decode(), the method Request::getContent() can be used.

$content = $request->getContent();

Additional useful informations on HTTP requests in Symfony can be found on the HttpFoundation package's documentation.

Is this still the way to go for functions that do not have the Request parameter? (e.g. in private functions of the controller class for example)
1 
use Symfony\Component\HttpFoundation\Request;

public function indexAction(Request $request, $id) {

    $post = $request->request->all();

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

}

Thanks , you can also use above code

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

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

This does not answer the question at all. The person asking the question already hast access to the request object.
@LaytonEverson sorry but you are mistaken, his method // $this->getRequest() is deprecated since 2.4, that's why it's not working, so he doesn't really have access to the request object ;)
Although you are not wrong about that, asker is wondering what method retrieves a variables from the request object. @Cerad answered this question correct. Not only did he provide the correct way to access the Request object, he also answer the question question.

public function indexAction(Request $request)
{
   $data = $request->get('corresponding_arg');
   // this also works
   $data1 = $request->query->get('corresponding_arg1');

While this code may answer the question, it would be better to include some context, explaining how it works and when to use it. Code-only answers are not useful in the long run.
