Symfony 2.3/2.4 Standalone Form Component

Question

Symfony Framework 외부에서 사용하기 위해 Symfony 2.3 Form Standalone 구성 요소를 사용하려고합니다.

나는 위의 URL 코드 좋은에서 다음 URL을 http://n.clavaud.free.fr/blog/index.php?article31/symfony2-standalone-form-component-tutorial

을 시도했지만 그것은 심포니 프레임 워크의 이전 버전을 기반으로합니다.

심포니 2.3을 사용하는 동안

나는 URL에 위와 같이 동일한 코드를 원하지만 그것은 심포니 2.3 또는 다른 제안에 작동합니다 문제는 무엇입니까?

내가 코드 아래 사용하고

난 당신이 인터페이스의 인스턴스를 위해 노력하고

Fatal error: Cannot instantiate interface Symfony\Component\Form\FormRendererInterface in /var/www/new/test.php on line 193

Answer 1

이 오류가 무엇입니까 :

$form_helper = new FormHelper(new FormRendererInterface()); 

인터페이스하는 클래스 및 없습니다 인스턴스화 할 수 없습니다 (http://php.net/interface 참조).
