Adds support of JSON requests for Forms:
Symfony forms will be able to handle both JSON POST/PUT/PATCH/DELETE requests and standard GET/POST requests (as they are by default).
The JsonHttpFoundationRequestHandler handles the request: If the request content-type is JSON, it decodes the JSON request content as an array and submits the form with its data.
Otherwise, it lets the default behaviour operate: the HttpFoundationRequestHandler will handle the request. So all your non-json form request will be treated just the way they've always been.
Require ElaoJsonHttpFormBundle:
composer require elao/json-http-form-bundleGiven a Rocket entity with two attributes: name (a string) and colors (an array of strings).
The following form and controller are meant to create a new instance of Rocket:
<?php
namespace AppBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
// ...
class RocketType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', TextType::class)
->add('colors', ChoiceType::class, [
'multiple' => true,
'choices' => [
'White' => 'white',
'Orange' => 'orange',
'Blonde' => 'blonde',
'Pink' => 'pink',
'Blue' => 'blue',
'Brown' => 'brown',
]
])
;
}
// ...
}<?php
namespace AppBundle\Controller;
// ...
class RocketController extends Controller
{
public function newAction(Request $request)
{
$rocket = new Rocket();
$form = $this->createForm(new RocketType(), $rocket)->getForm();
if ($form->handleRequest($request)->isSubmitted() && $form->isValid()) {
// The $rocket object is now correctly hydrated with the data from the form.
// Whether the request is a classic GET/POST request or a JSON one.
}
}
}The Controller and Form above now accept the following JSON POST request:
POST /rockets HTTP/1.1
Accept: application/json
Content-Type: application/json
Content-Length: 43
{"name":"Melies","colors":["pink","brown"]}It works \o/
