php – Symfony2 – 为自定义表单类型创建模板

这是我的完整配置：

VideoFileType.php

<?php
# src/Acme/PhotoBundle/Form/Type/ThumbnailType.php

namespace OSCMediaBundleFormType;

use OSCMediaBundleManagerVideoFileManager;
use SymfonyComponentDependencyInjectionContainer;
use SymfonyComponentFormAbstractType;
use SymfonyComponentFormExtensionCoreChoiceListObjectChoiceList;
use SymfonyComponentFormFormBuilderInterface;
use SymfonyComponentFormFormEvent;
use SymfonyComponentFormFormEvents;
use SymfonyComponentOptionsResolverOptionsResolverInterface;

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','image');
        $builder->add('file','file');
        $builder->add('videoPreset','choice',array(
            'choices' => $this->videoPresets,'multiple' => false,'required' => true
        ));
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'OSCMediaBundleEntityVideoFile'
        ));
    }

    public function getDefaultOptions(array $options) {
        return array('data_class' => 'OSCMediaBundleEntityVideoFile');
    }

    public function getName()
    {
        return 'video_file';
    }
}

这是我将表单声明为服务的地方：

osc_media.form.type.video_file:
    class: %osc_media.form.type.video_file.class%
    arguments: [@service_container]
    tags:
        - { name: form.type,alias: video_file }

简单地说,我想要的是覆盖表单模板.正如文档中提到的,我创建了名为OSCMediaBundle的模板：Form：video_file.html.twig(类似于表单的getName方法的返回字符串)：

这不是我的最终模板,只是一个测试：

{% block video_file_widget %}
        {% spaceless %}
            <tr> allo
                <td>
                    {{ form_widget(videoPreset) }}
                </td>
            </tr>
        {% endspaceless %}
    {% endblock %}

现在,在我的控制器中,我有以下内容：

public function createAction(Request $request)
    {
        $videoFile = new VideoFile();

        $form = $this->createForm('video_file',$videoFile);

        if ($request->getMethod() == 'POST') {
            $form->handleRequest($request);

            if ($form->isValid()) {
                $em = $this->get('doctrine.orm.entity_manager');
                $videoFile = $form->getData();

                $em->persist($videoFile);
                $em->flush();
            }
        }

        return $this->render('OSCMySportBundle:Video:create.html.twig',array(
            'form' => $form->createView()
        ));
    }

在我的模板OSCMySportBundle：Video：create.html.twig

{{ form(form) }}

最后,我在配置中声明了表单：

twig:
    debug:            %kernel.debug%
    strict_variables: %kernel.debug%
    globals:
        locales: %locales%
    form:
        resources:
            # ...
            - 'SonataFormatterBundle:Form:formatter.html.twig'
            - 'OSCMediaBundle:Form:video_file.html.twig'

我清除了缓存和一切,但我无法显示自定义模板.我不知道我在这里做错了什么.

Edit1：在@ Zalex的评论之后,我在我的模板中将video_file重命名为video_file_widget.但是,我仍然没有看到和最终的HTML.

Edit2：如果我在模板中添加一个文本(‘allo’),则显示’allo’但不显示和标签,所以基本上,模板已加载.
