Question

我想向每个实体插入多个图像因为这段代码效果很好，但它只需要添加最后一张图片。有没有办法使用简单的表格上传Symfony2的所有图像？

控制器

            return new RedirectResponse($this->get('router')->generate('examen_coupedumonde_homepage'));
        }

    }

    return $this->render('ExamenCoupedumondeBundle:Default:insertion.html.twig',array('form'=>$form->createView()));
}

有人帮我，谢谢你:)。

我认为你必须嵌入一组表格（图片）：见http://symfony.com/doc/current/cookbook/form/form_collections.html。这是一种方式......

好吧，您可以使用PHP和Doctrine轻松添加多个文件。

if(isset($_FILES['files']))
    {
        $errors= array();
        foreach($_FILES['files']['tmp_name'] as $key => $tmp_name )
        {
            $file_name = $_FILES['files']['name'][$key];
            $file_size =$_FILES['files']['size'][$key];
            $file_tmp =$_FILES['files']['tmp_name'][$key];
            $file_type=$_FILES['files']['type'][$key];
            if($file_size > 6097152) //whatever size you want
            {
                $errors[]='File size must be less than 6 MB';
            }
            $entity = new Entity; //your file entity

            //Do whatever you want with the entity...

            $request = $this->get('request');
            $em = $this->getDoctrine()->getManager();
            $em->persist($entity);
            $em->flush(); 
            $desired_dir=__DIR__.'/../../../../web/[Your desired folder]/'.$entity->getId()."/";
            if(empty($errors)==true)
            {
                if(is_dir($desired_dir)==false)
                {
                    mkdir("$desired_dir", 0700);        // Create directory if it does not exist
                }
                if(is_dir("$desired_dir/".$file_name)==false)
                {
                    move_uploaded_file($file_tmp,__DIR__.'/../../../../web/[Your desired folder]/'.$entity->getId()."/".$file_name);
                }
                else
                {                                  //rename the file if another one exist
                    $new_dir=__DIR__.'/../../../../web/Flightpics/'.$flight->getId()."/".$file_name.time();
                    rename($file_tmp,$new_dir) ;
                }
            }
            else
            {
                //print errors if needed
            }
        }
        if(empty($error)){
                //print success if needed
        }
    }

所有文件都将被处理到您的网站/ [您的文件夹] / [您的实体ID]文件夹中。
