Question

我在查询symfony2时遇到问题，请看这张图片：http://snapplr.com/snap/yt84

当我尝试创建一个新的图库实体（在我的服务器上上传图片文件）时，我收到此错误，

但是当我尝试更新我在数据库中添加手册的实体时，它就可以了。

这是我的实体

<?php

        // On vérifie si on avait déjà un fichier pour cette entité

            // On sauvegarde l'extension du fichier pour le supprimer plus tard
            $this->tempFile = $this->path;

        }
    }
 
    public function getFile()
    {
        return $this->file;
    }
}

这是我的控制器的动作：

public function createGalleryAction(Request $request, $slug){
        $entity = new Gallery();
        $em = $this->getDoctrine()->getManager();
        $page = $em->getRepository('PageBundle:Page')->findOneBySlug($slug);
        $page = $em->getRepository('PageBundle:Page')->find($page->getId());

        $entity->setPage($page);

        $form = $this->createForm(new GalleryType(), $entity);
        $form->bind($request);
        if ($form->isValid()) {
            $em->persist($entity);
            $em->flush();
            $this->get('session')->getFlashBag()->add('success', 'L\'image a été crée !');
            if(isset($_POST['create_new'])){
                return $this->redirect($this->generateUrl('pa_gallery_new', array('slug'                                                        => $slug)));
            }else{
                return $this->redirect($this->generateUrl('pa_gallery_show', array('slug'                                                        => $slug) ));
            }  
        }

        return $this->render('::crudGenerator/new.html.twig', array(
            'entity' => $entity,
            'form'   => $form->createView(),
            'actionList'            => $this->generateUrl('pa'),
            'actionGalleryList'     => $this->generateUrl('pa_gallery_show', array('slug'   => $slug)),
            'actionCreate'      => $this->generateUrl('pa_gallery_create', array('slug'                                                        => $slug)),
            'name'                  => 'page',
            'subName'               => 'galerie photos',
        ));
    }

order是mysql中的保留关键字（用于order by），并在保留关键字导致语法错误后命名列。将order字段重命名为其他字段可以解决问题。
