Question

我尝试了各种各样的方式，但我无法回复isValid()，所以我想确保首先纠正这一部分。

        var_dump('form is coming back as not isValid(), make sure debug is off, heres our errors list:<br>');
        var_dump($form->getErrorsAsString());
        echo '</pre>';
    }

        //its not a POST, or  POST is invalid, so display the form
        return $this->render($this->someTemplate, array(
            'form' => $form->createView(),
        ));
    }
}

1）在条件操作期间传递此表单对象的方式上我有点困惑（oop wise）。我是否需要在操作时将其连接起来，或者symfony提供什么来避免这种情况，或者我只是将对象传递给错误的？看这个例子来更好地理解这个问题。例如$form .= $form->getForm();如何在操作过程中正确地连接这个表单对象，就像我使用三元时那样，让我自己说，当我传递这个对象时，它的同一个对象，而不是一个新对象。

2）看到可能导致破损的其他任何问题？

编辑 @Chausser 这是最新的代码，简化了一点，我现在正在使用一些显而易见的稀有例子http://api.symfony.com/2.5/Symfony/Component/Form/Forms.html。它还没有回来isValid()。请比较我以前和表单对象的新用法示例。

 <?php
 /**
  * @param Request $request
  * @Route("/do/something", name="do_something",  options={"expose"=true})
  * @Method({"GET", "POST"})
  * @return mixed
  */
public function doSomethingAction(Request $request)
{
    $defaultData = array(
        'comment' => 'Type your comment here',
        'name' => 'Type your name here',
        'resources' => '{}',
        'warning' => 'Warning, your still in debug mode on your controller.php'
    );

    $resourceInputType = $this->debug ? 'text' : 'hidden';

    $formFactory = Forms::createFormFactory();
    $form = $formFactory
        ->createBuilder()
        ->setAction($this->generateUrl('do_something'))
        ->add("emails", 'text', array(
            'label' => "Recipient's email address (separate with a comma)",
            'constraints' => array(// constraints here
            ),
        ))
        ->add('comment', 'textarea', array(
            'label' => "Leave a comment",
        ))
        ->add('name', 'text', array(
            'label' => "Your name",
            'constraints' => array(// constraints here
            ),
        ))
        ->add('email', 'email', array(
            'label' => "Your email address",
            'constraints' => array(// constraints here
            ),
        ))
        ->add('copy', 'checkbox', array(
            'label' => "Send me a copy",
            'required' => false,
        ))
        ->add('cancel', 'button', array(
            'label' => "Cancel",
            'attr' => array('class' => 'btn-branded'),
        ))
        ->add('save', 'submit', array(
            'label' => "Email Resources",
            'attr' => array('class' => 'btn-branded'),
        ))
        ->add('resources', $resourceInputType, array(
            'constraints' => array(// constraints here
            ),
        ))
        ->getForm();

    $form->handleRequest($request);

    //validate
    if ($form->isValid()) {

        $data = $form->getData();

    //run some data checks, then fire it off
        $something = $this->DoSomething($data);
        return $something;
    //other options for returning
    //$return=array("responseCode"=>200,  "data"=>$data);
    // $return=json_encode($something); //json encode the array
    // return new Response($return,200,array('Content-Type'=>'application/json'));//make sure it has the correct content type
    } else {
        echo '<pre>';
        var_dump('form is coming back as not isValid(), make sure debug is off, heres our errors list:<br>');
        var_dump($form->getErrorsAsString());
        echo '</pre>';
    }

    //its not a POST, or  POST is invalid, so display the form
    return $this->render($this->someTemplate, array(
        'form' => $form->createView(),
    ));
}

修改所以现在我的编辑后得到表单不尝试和haldne请求，除非它的POST请求，而不是GET请求

    if($request && $request->getMethod() == 'POST'){

    $form->handleRequest($request);

    //validate
    if ($form->isValid()) {

        $data = $form->getData();

        //run some data checks, then fire it off
        $something = $this->DoSomething($data);
        return $something;
        //other options for returning
        //$return=array("responseCode"=>200,  "data"=>$data);
        // $return=json_encode($something); //json encode the array
        // return new Response($return,200,array('Content-Type'=>'application/json'));//make sure it has the correct content type
    } else {
        echo '<pre>';
        var_dump('form is coming back as not isValid(), make sure debug is off, heres our errors list:<br>');
        var_dump($form->getErrorsAsString());
        echo '</pre>';
    }
}

导致下面提到的控制器错误

Answer 1

好吧，看起来好像验证器扩展名在使用时正在破坏，因为HttpFoundationExtension（）没有包含在内。显然，要使用验证器或工厂构建器（不确定哪个），它也需要此扩展。

工作示例，从最初的示例复制，添加了工作部件。

        return $this->render($this->someTemplate, array(

    }
}

symfony表单没有回复有效，我有表单对象问题吗？
