我从SonataMediaBundle开始,当我想上传图片时遇到一些问题(不幸的是文档不太清楚)
我继续:
我想在创建新闻表单中上传图片,所以:
在新闻实体中:
/**
* @ORM\ManyToOne(targetEntity="\Application\Sonata\MediaBundle\Entity\Media", cascade={"all"})
* @ORM\JoinColumn(nullable=false)
*/
protected $imageNews;
在NewsType中,我在buildForm中添加了字段:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title')
->add('summary', 'text', array(
'required' => false
))
->add('body', 'textarea', array('attr' => array(
'class' => 'ckeditor',
)))
->add('imageNews', 'sonata_media_type', array(
'provider' => 'sonata.media.provider.image',
'context' => 'news'
));
// ->add('categories', 'taxonomy')
;
}
我的文件config.yml
Doctrine :
orm:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
# SonataMediaBundle
sonata_media:
default_context: default
db_driver: doctrine_orm # or doctrine_mongodb, doctrine_phpcr

filesystem:

我想我错过了什么,你能告诉我遗失的东西吗? 我设法显示上传但是当我验证表单时,我看到imageNews对象是Null(var_dump)
谢谢!
答案 0 :(得分:2)
此处的问题相同,添加此表单模板解决了问题
twig:
debug: %kernel.debug%
strict_variables: %kernel.debug%
form:
resources:
# other files
- 'SonataMediaBundle:Form:media_widgets.html.twig'
http://sonata-project.org/bundles/media/2-2/doc/reference/form.html
该模板中的必须是make的关键词
