我想在Symfony中将表单（ImageType）嵌入到另一个表单（VideoFileType）中。我的第一个表单包含文件输入。基本上，它是根据已经定义的许多预设上传然后调整大小的图像。
我的第二个表单将嵌入ImageType表单。第二种形式是VideoFileType形式，其中包含ImageType形式。基本上，ImageType将充当视频文件的缩略图。 VideoFileType还将包含第二个文件输入以上传videoFile，最后还有一个选择框以选择相应的VideoPreset。
回顾一下，VideoFileType会嵌入ImageType。
我的班级结构很相似。我有一个VideoFile，其Thumbnail属性为Image
当我只显示ImageType并上传图片时，一切正常。
将ImageType ：
class ImageType extends AbstractType
{
private $imageManager;
public function __construct(ImageManager $imageManager) {
$this->imageManager = $imageManager;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('file', 'file');
$builder->addEventListener(
FormEvents::POST_SUBMIT,
array($this, 'onPostSetData')
);
}
public function getDefaultOptions(array $options) {
return array('data_class' => 'OSC\MediaBundle\Entity\Image');
}
public function onPostSetData(FormEvent $event) {
$image = $event->getData();
$form = $event->getForm();
//We need here to update the video file with the new content
$image = $this->imageManager->uploadImage($image);
$event->setData($image);
}
public function getName()
{
return 'image';
}
}
VideoFileType
class VideoFileType extends AbstractType
{
public $container;
public $videoPresets = [];
public function __construct(Container $container) {
$this->container = $container;
$videoPresets = $container->getParameter('osc_media.video.presets');
foreach ($videoPresets as $key => $videoPreset) {
array_push($this->videoPresets, $key);
}
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('thumbnail', new ImageType($this->container->get('osc_media.manager.image')));
$builder->add('file', 'file');
$builder->add('videoPreset', 'choice', array(
'choices' => $this->videoPresets,
'multiple' => false,
'required' => true
));
$builder->addEventListener(
FormEvents::POST_SUBMIT,
array($this, 'onPostSetData')
);
$builder->add('save', 'submit');
}
public function onPostSetData(FormEvent $event) {
$videoFile = $event->getData();
$form = $event->getForm();

但是，当我尝试创建VideoFileType表单时，出现以下错误：
The form's view data is expected to be of type scalar, array or an instance of \ArrayAccess, but is an instance of class OSC\MediaBundle\Entity\Image. You can avoid this error by setting the "data_class" option to "OSC\MediaBundle\Entity\Image" or by adding a view transformer that transforms an instance of class OSC\MediaBundle\Entity\Image to scalar, array or an instance of \ArrayAccess.
所以，我想要的是，ImageFileType（OnPostSetData）的处理在嵌入VideoFileType时与单独使用时一样成功执行。
然后，完成后，我希望Image对象作为缩略图属性插入VideoFile。之后，它应该在VideoFileType的OnPostSetData方法中完成处理。
如果它不可行，我只是在VideoFileType中重新创建ImageType的逻辑，这不是什么大问题。但是，我觉得如果我可以重用ImageFileType就可以了。
答案 0 :(得分：2)
我不是100％肯定，但尝试将此功能添加到您的ImageType课程中。
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
....
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
}
并更改班级buildForm中VideoFileType内缩略图属性的配置。
$builder->add('thumbnail',
new ImageType($this->container->get('osc_media.manager.image')),
array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
答案 1 :(得分：0)
如果你想扩展formtype，
，这很容易就这样做：
使用getParent方法扩展您的第二个表单
public function getParent（） { 返回'图像'; }
这样做你在第二个表单中的字段与第一个字段相同 你可以添加更多。
