Javascript 数据库中未显示名称年龄和上载文件

StudentController.php

我正在symfony中上载图像任务，但我的数据库没有显示这些项目，但我的程序工作正常，图像存储在web\uploads\photos中

这是我的StudentController.php，任何人都可以帮助解决这个问题

<?php 
namespace AppBundle\Controller; 

use AppBundle\Entity\Student; 
use AppBundle\Form\FormValidationType; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 

use Symfony\Component\HttpFoundation\Request; 
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Form\Extension\Core\Type\TextType; 
use Symfony\Component\Form\Extension\Core\Type\FileType; 
use Symfony\Component\Form\Extension\Core\Type\SubmitType;  

class StudentController extends Controller {    
   /** 
      * @Route("/student/new") 
   */ 
   public function newAction(Request $request) { 
      $student = new Student(); 
      $form = $this->createFormBuilder($student) 
         ->add('name', TextType::class) 
         ->add('age', TextType::class) 
         ->add('photo', FileType::class, array('label' => 'Photo (png, jpeg)')) 
         ->add('save', SubmitType::class, array('label' => 'Submit')) 
         ->getForm(); 

      $form->handleRequest($request); 
      if ($form->isSubmitted() && $form->isValid()) { 
         $file = $student->getPhoto(); 
         $fileName = md5(uniqid()).'.'.$file->guessExtension(); 
         $file->move($this->getParameter('photos_directory'), $fileName); 
         $student->setPhoto($fileName); 
         return new Response("User photo is successfully uploaded."); 
      } else { 
         return $this->render('student/new.html.twig', array( 
            'form' => $form->createView(), 
         )); 
      } 
   }   
}

您需要使用条令实体管理器来持久化和刷新数据库中的对象

$entityManager->persist($yourEntity);
$entityManager->flush($yourEntity);

我建议你阅读关于教义和形式的symfony文档

您的控制器操作已修复：

<?php
class StudentController extends Controller {    
   /** 
      * @Route("/student/new") 
   */ 
   public function newAction(Request $request) { 
      $student = new Student(); 
      $form = $this->createFormBuilder($student) 
         ->add('name', TextType::class) 
         ->add('age', TextType::class) 
         ->add('photo', FileType::class, array('label' => 'Photo (png, jpeg)')) 
         ->add('save', SubmitType::class, array('label' => 'Submit')) 
         ->getForm(); 

      $form->handleRequest($request); 
      if ($form->isSubmitted() && $form->isValid()) { 
         $file = $student->getPhoto(); 
         $fileName = md5(uniqid()).'.'.$file->guessExtension(); 
         $file->move($this->getParameter('photos_directory'), $fileName); 
         $student->setPhoto($fileName); 
         $em = $this->getManager()->getDoctrine();
         $em->persist($student);
         $em->flush();
         return new Response("User photo is successfully uploaded."); 
      } else { 
         return $this->render('student/new.html.twig', array( 
            'form' => $form->createView(), 
         )); 
      } 
   }   
}
