How to get the request parameters in Symfony 2?

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');

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 }

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()
