How to Get the Request Parameters in Symfony 2

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');

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.

Getting all request parameters in Symfony 2

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

Symfony Request get all url Parameters

Did you try:

$parametersToValidate = $request->query->all();

Get parameters from URL in Controller Symfony2

Do like this, if you can't find QS values:

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

it shows all QS values;

In your case, you can access your QS data by:

$formData = $request->query->get('search_form');

or

$formData = $request->query->get($form->getName());

it returns array of values, after that you can access startPoints like this:

$formData['startPoints']

Symfony2 retrieve the parameter values from URL

use Symfony\Component\HttpFoundation\Request;
.
.
public function MyAction()
{
    $request = $this->getRequest();
    $amount =$request->attributes->get('amount'); //replace this line in above code
    echo 'Amount ='.$amount;
    exit;
}

Symfony2: How to get request parameter

Not a good thing but you can still do. Normally you would pass the info to Twig from the controller like @Maerlyn pointed out.

Get route parameters in Twig.

{{ app.request.attributes.get('_route_params') }}

AND

Gets whole bundle name in Twig.

{{ app.request.attributes.get("_controller") }}

Get route name in Twig.

{{ app.request.attributes.get('_route') }}

How to get all post parameters in Symfony2?

$this->get('request')->request->all()

Symfony2 Form overwrites 'GET Request Parameters'

@Thiago Rodrigues answer pushed me towards the right direction. Here is how I solved it.

I added the sort and direction fields as hidden fields to my form.

class AttributeFilterType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {

        if ($request->get('sort')) {
            $builder->add('sort', 'hidden', array(
                'data' => $request->get('sort'),
            ));
            $builder->add('direction', 'hidden', array(
                'data' => $request->get('direction'),
            ));
        }
    }
}

To make sure that the Values of the Form are not overwritten by old legacy values of the form. I made changes to the request, as follows (note: attributeFilter is the name of my Form):

/**
 * This function will analyze the given request.
 *
 * It will correct and set the settings of the given sort Values
 *
 * If the request contains sort and attributeFilter, always take the sort and overwrite the attributeFilter
 * If only the attributeFilter is given, set the sort=Attributefilter
 *
 * @param Request $request
 */
protected function manipulateParameterBag(Request $request)
{
    $parameterBag = $request->query;

    $sort = $parameterBag->get('sort');
    $direction = $parameterBag->get('direction');
    $attributeFilter = $parameterBag->get('attributeFilter');
    if ($sort && $direction) {
        if ($attributeFilter) {
            $attributeFilter['sort'] = $sort;
            $attributeFilter['direction'] = $direction;
            $parameterBag->set('attributeFilter', $attributeFilter);
        }
    } elseif ($attributeFilter) {
        $parameterBag->set('sort', $attributeFilter['sort']);
        $parameterBag->set('direction', $attributeFilter['direction']);
    }

    $request->query = $parameterBag;
    return $request;
}

Hope this helps the next person that tries to accomplish the same.
