我试图从实体创建一个表单，但遇到了一些麻烦。
这是我的FormType
namespace AppBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
class EditPhotoFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('title', 'text');
$builder->add('description', 'textarea');
$builder->add('category', 'choice', array(
'choices' => array(
'1' => 'categories.uncategorized',
'categories.photography.photography' => array(
'5' => 'categories.photography.abstract',
'6' => 'categories.photography.animals',
'7' => 'categories.photography.blackandwhite',
'8' => 'categories.photography.architecture',
'9' => 'categories.photography.fashion',
'10' => 'categories.photography.food',
'11' => 'categories.photography.landscapes',
'12' => 'categories.photography.macro',
'13' => 'categories.photography.people',
'14' => 'categories.photography.sport'
),
'categories.painting.painting' => array(
'15' => 'categories.painting.landscapes',
'16' => 'categories.painting.seascapes',
'17' => 'categories.painting.portrait',
'18' => 'categories.painting.stilllife',
'19' => 'categories.painting.architecture',
'20' => 'categories.painting.fantasy'
),
'categories.3d.3d' => array(
'21' => 'categories.3d.interiors',
'22' => 'categories.3d.exteriors',
'23' => 'categories.3d.creative'
),
),
));
}
public function getName()
{
return 'app_photo_edit';
}
}
这是我的控制器。
$em = $this->getDoctrine()->getManager();
$photo = $em->getRepository('AppBundle:Photo')->find($photoId);
$form = $this->createForm('app_photo_edit', $photo);
return $this->render('AdminBundle::edit.html.twig', array('form' => $form->createView(), 'photo' => $photo));

我得到错误：“object”类型的值无法转换为有效的数组键。
问题出在FormType类别中，但我不知道如何正确地做到这一点。
谢谢

我认为问题是由嵌套数组引起的：
'categories.photography.photography' => array(...)
如果你把简单的密钥=＆gt;值数组它应该工作。例如：
$builder->add('type', 'choice',
array(
'label'=>'My own label',
'choices'=>array('verb'=>'Displayed verb', 'noun'=>'Displayed noun', 'adjective'=>'Displayed adjective', 'adverb'=>'Displayed adverb')));
对于您的表单，我建议您创建3个单独的选择字段。

解决代码中的所有问题，您的代码运行得更好。
