扩展 SymfonyForm 组件。添加新的表单类型 DropzoneType

安装

composer require emrdev/symfony-dropzone

资源

将 dropzone 库添加到项目的模板中

<script src="https://unpkg.com/dropzone@6.0.0-beta.1/dist/dropzone-min.js"></script>
<link href="https://unpkg.com/dropzone@6.0.0-beta.1/dist/dropzone.css" rel="stylesheet" type="text/css" />

用法

public function buildForm(\Symfony\Component\Form\FormBuilderInterface $builder, array $options)
{ 

    // userFiles is OneToMany
    $builder->add('userFiles', DropzoneType::class, [
        'class' => File::class,
        'maxFiles' => 6,
        'uploadHandler'=>'uploadHandler',  // route name
        'removeHandler'=> 'removeHandler'// route name
   ]);
}

示例：路由 uploadHandler/removeHandler

/**
     * @Route("/uploadhandler", name="uploadHandler")
     */
    public function uploadhandler(Request $request, ImageUploader $uploader) { 
        $doc = $uploader->upload($request->files->get('file'));  
        $file = new File(); 
        $file->setSrc($doc['src']);
        ...

        $this->getDoctrine()->getManager()->persist($file);
        $this->getDoctrine()->getManager()->flush();
        return new JsonResponse($file);
    }


    /**
     * @Route("/removeHandler/{id}", name="removeHandler")
     */
    public function removeHandler(Request $request,File $file = null) {
        $this->getDoctrine()->getManager()->remove($file);
        $this->getDoctrine()->getManager()->flush();
        return new JsonResponse(true);
    }
