Simplest way to bind Request to DTO/Commands.

Bindto helps you to work with API and data validation using DTO and Commands.

Is really fast (it doesn't use Reflection) and binds the Request against your class.

It's the smartest way to stop using the slow and complex Symfony Form component for API.


composer require pugx/bindto


Example, you have to create a Post/Patch/Put Api

1. Create a simple class that is the body of a request

protip: you can use with Symfony validation component annotations
use Symfony\Component\Validator\Constraints as Assert;

Class CreateFeedback {

     * @Assert\NotBlank(groups={"POST"})
     * @Assert\Type(type="string")
    public $subject;

     * @Assert\NotNull(groups={"POST"})
     * @Assert\Type(type="string")
     * @Assert\Length(
     *      min = 10,
     *      max = 500)
    public $body;

2. In your controller

if you use Silex you may want to enforce the input validation, improving the example at http://silex.sensiolabs.org/doc/usage.html#example-post-route:

require_once __DIR__.'/../vendor/autoload.php';

use Bindto\Binder;

$app = new Silex\Application();

$app->post('/feedback', function (Request $request) {

    $binder = Binder::createSimpleProductionBinder();
    $result = $binder->bind($request, CreateFeedback::class);
    if (!$result->isValid()) {
        throw new \Exception($result->getViolations());
    $createFeedBack = $result->getData();
    mail($createFeedBack->subject, '[YourSite] Feedback', $createFeedBack->body);

    return new Response('Thank you for your feedback!', 201);


PATCH support with partial modification

Use the validation groups if you want to PATCH partially:

 * @Assert\NotNull(groups={"POST"})
 * @Assert\Type(type="string")
 * @Assert\Length(
 *      min = 10,
 *      max = 500)
public $body;

With a POST request all the assertions will be used, with a PUT and PATCH only the Type and Length assertions.
