symfony 3 ChoiceType is not无效

我有一个非常简单的脚本。它从表中读取ID和NAME，并将它们作为选项添加到我的choiceType中。symfony 3 ChoiceType is not无效

已解决 查看上一个脚本。您必须再次在表单中添加所有选项。

这是行动。

/** 
* @Route("/monitor/setup/carousel", name="SetupCarousel") 
*/ 
public function SetupCarouselManageAction(Request $request){ 
    $repository = $this->getDoctrine()->getRepository("AppBundle:Picture"); 
    $pictures = $repository->findAll(); 
    $p = array(); 
    $p['-- Bitte Bild setzen'] = -1; 
    foreach($pictures as $pic){ 
     $p[$pic->getTitle()] = $pic->getId(); 
    } 
    $carousel = new Carousel(); 
    $FormCarousel = $this->createForm(CarouselType::class, $carousel, array(
      'pictures' => $p, 
      'action' => $this->generateUrl('SetupInputCarousel') 
    )); 

    $render = $this->render('SetupCarousel.html.twig',array(
      'form_event' => $FormCarousel->createView() 

    )); 
    return $render; 
}

中的页面类型：

class CarouselType extends AbstractType{ 
public function buildForm(FormBuilderInterface $builder, array $options){ 

    $builder 
     ->add("bildId", ChoiceType::class, 
       array('choices' => $options['pictures'])) 
     ->add('submit', SubmitType::class); 
} 
public function configureOptions(OptionsResolver $resolver) 
{ 
    $resolver 
    ->setDefaults(array(
      'data_class' => Carousel::class, 
      'pictures'=> array('array'))) 
    ->setAllowedTypes('pictures', array('array')) 
    ; 
} 
}

到目前为止，一切都很好。在我的页面上获得ChoiceType Box，我可以选择我想要的条目并提交。如果我想检查数据是否有效，则失败。

这里我实体

class Carousel{ 
/** 
* @ORM\Column(type="integer") 
* @ORM\Id 
* @ORM\GeneratedValue(strategy="AUTO") 
*/ 
protected $id; 

/** @ORM\Column(type="integer") */ 
protected $bildId; 

/**@ORM\Column(type="string") */ 
protected $text;

这是我得到的数据回首的刹那的方式。

/** 
* @Route("/monitor/setup/input/carousel",name="SetupInputCarousel") 
*/ 
public function SetupInputCarouselAction(Request $request){ 
    $carousel = new Carousel(); 
    $form = $this->createForm(CarouselType::class,$carousel); 
    $form->handleRequest($request); 
    if($form->isSubmitted()){ 

     //pease rework this in future 
     $data = $request->request->get('carousel'); 
     $carousel->setBildId($data['bildId']); 

     $carousel->setText($data['text']); 

     if($carousel->getBildId() == -1){ 
      return $this->redirectToRoute('SetupHome'); 
     } 
     $em = $this->getDoctrine()->getManager(); 
     $em->persist($carousel); 
     $em->flush(); 
    return $this->redirectToRoute('SetupCarousel'); 

}

有没有人有任何想法，为什么这个下面的脚本不起作用？这是我可以在我的项目中的所有其他页面上完成的方式。

public function SetupInputEventsAction(Request $request){ 

    //YOU HAVE TO ADD THE ORIGINAL OPTIONS, THIS SOLVE THE PROBLEM 
    $repository = $this->getDoctrine()->getRepository("AppBundle:Picture"); 
    $pictures = $repository->findAll(); 
    $p = array(); 
    $p['-- Bitte Bild setzen'] = -1; 
    foreach($pictures as $pic){ 
     /** @var pic Picture */ 
     $p[$pic->getTitle()] = $pic->getId(); 
    } 
    $carousel = new Carousel(); 
    $form = $this->createForm(CarouselType::class,$carousel, array(
      'pictures' => $p, 
      'action' => $this->generateUrl('SetupInputCarousel') 
      )); 

    /* 
    SEE WORKING ONE ABOVE 
    $event = new Carousel(); 
    $form = $this->createForm(CarouselType::class,$event);*/ 
    $form->handleRequest($request); 
    if($form->isSubmitted() && $form->isValid()){ 
     //handel type 
     $em = $this->getDoctrine()->getManager(); 
     $em->persist($event); 
     $em->flush(); 
    } 
    return $this->redirectToRoute('SetupEvents'); 
}

你呈现：'在树枝模板'form_widget（form._token）？ –

@ĐuroMandinić这是我如何打印\t {{form_start（form_event）}} {{form_widget（form_event）}} {{form_end（form_event）}} –

您是否收到任何验证错误消息？你怎么知道这个领域是无效的？ –

的Soluion很容易，你必须添加所有选项 “SetupInputEventsAction” 功能。

public function SetupInputEventsAction(Request $request){ 

//YOU HAVE TO ADD THE ORIGINAL OPTIONS, THIS SOLVE THE PROBLEM 
$repository = $this->getDoctrine()->getRepository("AppBundle:Picture"); 
$pictures = $repository->findAll(); 
$p = array(); 
$p['-- Bitte Bild setzen'] = -1; 
foreach($pictures as $pic){ 
    /** @var pic Picture */ 
    $p[$pic->getTitle()] = $pic->getId(); 
} 
$carousel = new Carousel(); 
$form = $this->createForm(CarouselType::class,$carousel, array(
     'pictures' => $p, 
     'action' => $this->generateUrl('SetupInputCarousel') 
     )); 

/* 
SEE WORKING ONE ABOVE 
$event = new Carousel(); 
$form = $this->createForm(CarouselType::class,$event);*/ 
$form->handleRequest($request); 
if($form->isSubmitted() && $form->isValid()){ 
    //handel type 
    $em = $this->getDoctrine()->getManager(); 
    $em->persist($event); 
    $em->flush(); 
} 
return $this->redirectToRoute('SetupEvents'); 
}
