Question

我正在使用Symfony 2.7开发一个网站！我刚开始学习它，我正在尝试上传文件，文件名保存在我的数据库中，但它没有上传到目录中任何人可以帮我这里是我的控制器和实体：控制器：

namespace institutionBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use institutionBundle\Entity\Classe;
use institutionBundle\Form\ClasseType;
use institutionBundle\Entity\Niveau;

use Doctrine\ORM\EntityRepository;
use Symfony\Component\DependencyInjection\ContainerInterface as Container;
/**
 * Classe controller.
 *
 */
class ClasseController extends Controller
{
    public function newAction(request $request,$institut)
    {
        $em = $this->getDoctrine()->getManager();
        $classe = new Classe();
        $form = $this->createFormBuilder($classe)
            ->add('nom','text',array('required'=>true,'attr'=>array('class'=>'form-control','placeholder'=>'Entrez le nom')))

            ->add('niveau', 'entity', array(
                'attr'=>array('class'=>'form-control'),
                'class' => 'institutionBundle:Niveau',
                'property' => 'nom',
                'query_builder' => function (EntityRepository $er)use ($institut) {
                    return $er->createQueryBuilder('i')
                        ->andWhere('i.institut = :niv')->setParameter('niv', $institut);
                }

            ))
           ->add('file')
           ->add('Ajouter','submit',array('attr'=>array('class'=>'btn btn-success of')))

            ->getForm();

        $form->handleRequest($request);
        $alert='';
        if ($form->isSubmitted() && $form->isValid()) {

            $x = $form->get('nom')->getData();


            $d = $em->createQuery("select d from institutionBundle:Classe d where (d.nom = :niv and d.institut = :inst )")
                ->setParameters(array('niv'=>$x,'inst'=>$institut))
                ->getResult();
                $num2 = count($d);
                if($num2>0){
                    $alert ='Cette Classe existe déjà!  Veuillez choisir un autre nom';

                }else{
                    $inst = $em->getRepository("institutionBundle:Institut")->find($institut);
                    $classe->upload();
                    $classe->setInstitut($inst);
                    $mats=$form->get('niveau')->getData();
                    foreach ($mats as $mat) {
                        $s = $em->getRepository("institutionBundle:Niveau")->find($mat);
                        $classe->setNiveau($s);
                    }
                    $em-> persist($classe);
                    $em->flush();

                    return $this->redirectToRoute('home_classes',array('institut'=>$institut));
                }
        }

        return $this->render('institutionBundle:Classe:new.html.twig', array(
            'form' => $form->createView(),'alert'=>$alert,'institut'=>$institut
        ));
    }

}

实体：

Answer 1

我会说你错过了Uploader服务。或许你没有在你的问题上发帖。

这可以帮到你： Symfony 2.7 Uploader Service

那里的代码与你的代码非常相似，所以应该很容易理解并转化为你的问题

Answer 2

我找到了解决方案

protected function getUploadRootDir()
        {
            // the absolute directory path where uploaded
            // documents should be saved
            return __DIR__.'/../../../web/'.$this->getUploadDir();
        }

Symfony 2.7上传文件
