嵌入 Symfony 文件表单
Embed Symfony file form
我想在 Symfony 中将一个表单 (ImageType) 嵌入到另一个表单 (VideoFileType) 中。我的第一个表单包含一个文件输入。基本上，它是一张将上传的图像，然后根据许多已经定义的预设调整大小。
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视频文件，最后是一个 select 框到 select 相应的 VideoPreset。
所以回顾一下，VideoFileType 将嵌入一个 ImageType。
我的class结构类似。我有一个 VideoFile，它有一个 Thumbnail 属性，它是一个 Image class
当我只显示 ImageType 并上传图片时，一切正常。
图片类型:
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');

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，我想要的是对 ImageFileType (OnPostSetData) 的处理，当嵌入 VideoFileType 中时与单独使用时一样成功。
然后，完成后，我希望将 Image 对象作为缩略图属性插入到 VideoFile 中。之后应该在VideoFileType的OnPostSetData方法里面完成处理。
如果不可行，我将简单地在 VideoFileType 中重新创建 ImageType 的逻辑，这没什么大不了的。但是，我觉得如果我可以重用 ImageFileType 就好了。
我不是 100% 确定，但请尝试将此功能添加到您的 ImageTypeclass。
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
....
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
}
并更改缩略图 属性 的配置 buildForm in class VideoFileType。
$builder->add('thumbnail',
new ImageType($this->container->get('osc_media.manager.image')),
array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
如果您想扩展 formtype，这非常容易，
就这样做：
- 将您的第一个表单定义为服务
使用 getParent 方法扩展您的第二个表单
public 函数 getParent()
{
return 'image';
}
这样做，你的第二个表单中的字段与第一个表单中的字段相同
你还可以再添加一些。
我想在 Symfony 中将一个表单 (ImageType) 嵌入到另一个表单 (VideoFileType) 中。我的第一个表单包含一个文件输入。基本上，它是一张将上传的图像，然后根据许多已经定义的预设调整大小。
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视频文件，最后是一个 select 框到 select 相应的 VideoPreset。

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，我想要的是对 ImageFileType (OnPostSetData) 的处理，当嵌入 VideoFileType 中时与单独使用时一样成功。
然后，完成后，我希望将 Image 对象作为缩略图属性插入到 VideoFile 中。之后应该在VideoFileType的OnPostSetData方法里面完成处理。
如果不可行，我将简单地在 VideoFileType 中重新创建 ImageType 的逻辑，这没什么大不了的。但是，我觉得如果我可以重用 ImageFileType 就好了。
我不是 100% 确定，但请尝试将此功能添加到您的 ImageTypeclass。
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
....
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
}
并更改缩略图 属性 的配置 buildForm in class VideoFileType。
$builder->add('thumbnail',
new ImageType($this->container->get('osc_media.manager.image')),
array(
'data_class' => 'OSC\MediaBundle\Entity\Image'
));
如果您想扩展 formtype，这非常容易，
就这样做：
- 将您的第一个表单定义为服务
使用 getParent 方法扩展您的第二个表单
public 函数 getParent() { return 'image'; }
这样做，你的第二个表单中的字段与第一个表单中的字段相同 你还可以再添加一些。
