StudentController.php
我在 symfony 中上传图片任务,但我的数据库没有显示这些项目,但我的程序正常工作并且图像存储在 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(),
));
}
}
}
**Student.php**

最佳答案
您需要使用 doctrine 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);
我建议您阅读有关原则和形式的 symfony 文档。
您的 Controller 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(),
));
}
}
}
