因为我有一个自定义构建的jQuery插件来将文件上传传递给我的symfony2 webapp,我正在寻找在控制器中处理此上传的方法.
我目前拥有的标准(非ajax)文件上传(并且适用于同步调用)看起来像这样
控制器节选
...
$entity = new Image();
$request = $this->getRequest();
$form = $this->createForm(new ImageType($createAction),$entity);
$form->bind($request); // <-- Find a way to make this connection manually?!
//check that a file was chosen
$fileExists = isset($entity->file);
if ( ($form->isValid()) && ($fileExists) ) {
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
}
...
class ImageType extends AbstractType
{
...
public function buildForm(FormBuilderInterface $builder,array $options)
{
$createAction = $this->createAction;
if ($createAction) {
$builder
->add('file')
;
}
$builder
->add('name','text',array('label' => 'Namn'))
;
}
...
}
正如我所理解的(或者说显然不明白)使用symfony2和doctrine的文件上传系统,在这个调用的引擎盖下有相当多的魔力
$form->bind($request);
例如,如果我跳过这个bind(),而是尝试像这样手动创建Image实体……
$request = $this->getRequest();
$parent = $request->request->get('parent');
$file = $request->request->get('file1');
$name = $request->request->get('name');
$entity->setName( $name );
$entity->setFile( $file );
$entity->setFolder( null );
…我发现它甚至没有setFile(),因此以其他方式处理.这是Image实体：

我找到了我想要的东西.要从控制器访问上传到symfony的文件,您只需执行以下操作：
$request = $this->getRequest();
$file = $request->files->get('file1'); //file1 being the name of my form field for the file
/* if your entity is set up like mine - like they teach you in the symfony2 cookbook
* file is actually a public property so you can just set it like this
**/
$entity->file = $file;
//and here's how you get the original name of that file
$entity->setName( $file->getClientOriginalName() );
