How to use Symfony2 Form Component Standalone

sf2_standalone_form.php

<?php
namespace Standalone\Form;

use \Symfony\Component\HttpFoundation as SHttp;
use \Symfony\Component\Form as SForm;
use \Symfony\Component\DependencyInjection as SDI;
use \Symfony\Bridge as SBridge;

//Register all your autoload function here
//...

//This is a Doctrine mapped entity class
//This should be placed in a seperate file
/**
 * @Table(name="person")
 */
class Person {
	/**
	 * @Id
	 * @GeneratedValue
	 * @Column(type="integer")
	 * @var string
	 */
	protected $id;

//The form class

//Create a default DI container which will be used later

//Here comes Doctrine init code (connection, event manager, entity manager, ...)
//Each component has to be put in the container (doctrine.connection, doctrine.entity_manager, ...)

	$container,
	array('default' => 'doctrine.connection'),
	array('default' => 'doctrine.entity_manager'),

//And store it in the default container

//Create a default FormFactory

//And store it in the defautl container

Hello. I have a question.

On line 103, you are instantiating a \Symfony\Component\Form\FormFactory, and passing the constructor an array.

However, the method signature for that constructor is:

public function __construct(FormRegistryInterface $registry, ResolvedFormTypeFactoryInterface $resolvedTypeFactory)

How is it working with you passing it an array, if it's expecting an object of type FormRegistryInterface?

Is your code outdated? Or am I misunderstanding something?

Also, I'd love to see an example of how to render this form now, especially if you're not using twig.

Hi, thanks for the hint,
I have only one question: do you have a sample of implementation without the DependencyInjection component ?
