错误：无法访问受保护的属性UserBundle \ Entity \ User :: $ id in C：\ WAMP \ WWW \ LoveMates的\ src \ ProfileBundle \控制器\ ProductController.php 第20行

这是我的控制器

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;

class ProductController extends Controller 
{
    public function productAction(Request $request)
    {

        $user = $this->container->get('security.context')->getToken()->getUser();
         if (!is_object($user) || !$user instanceof UserInterface) {
            throw new AccessDeniedException('This user does not have access to this section.');
        }  
        $product->user_id = $this->get('security.context')->getToken()->getUser()->id;
        $product = new Product();

        $form = $this->createFormBuilder($product)
        // ...
        ->add('image', 'file')
        ->add('imagename', 'text')
        ->add('upload', 'submit')
        ->getForm();    

        $form->handleRequest($request);

        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($product);
            $em->flush();
            $response= new Response('cool image upload successfully');
            return $response;
    }

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

这是我的实体

    public function getImage()
    {

    }

    /**

    }

    /**

    public function getId()
    {
        return $this->id;
    }




    /**

     * Get the current logged in User Object
     * @return \Symfony\Component\Security\Core\User\User

    public function getUserId()
    {
        return  $this->user_id;
    }
    /**
     * Set user_id
     *
     * @param integer $userId
     * @return Product
     */
    public function setUserId($userId)
    {
        $this->user_id = $userId;

        return $this;
    }

}

user_id的字段不保存正确的值，并且始终为null。你的帮助将不胜感激。

您需要执行此操作才能获取User：

的ID

$userId = $this->get('security.context')->getToken()->getUser()->getId();

编辑：您需要更改此行：

    $product->user_id = $this->get('security.context')->getToken()->getUser()->id;
    $product = new Product();

进入这个：

    $product = new Product();
    $product->user_id = $this->get('security.context')->getToken()->getUser()->getId();

试图在symfony的图像表中获取用户ID存储
