名称年龄和上传文件未显示在数据库中

Question

StudentController.php

我正在symfony中上传图像任务，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。

这是我的学生控制器.php任何人都可以帮助解决这个问题。

<?php 
namespace AppBundleController; 
use AppBundleEntityStudent; 
use AppBundleFormFormValidationType; 
use SymfonyBundleFrameworkBundleControllerController; 
use SensioBundleFrameworkExtraBundleConfigurationRoute; 
use SymfonyComponentHttpFoundationRequest; 
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentFormExtensionCoreTypeTextType; 
use SymfonyComponentFormExtensionCoreTypeFileType; 
use SymfonyComponentFormExtensionCoreTypeSubmitType;  
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(), 
)); 
} 
}   
}

您需要使用原则实体管理器来保留和刷新数据库中的对象。

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

我建议你阅读有关教义和形式的symfony文档。

已修复控制器操作：

<?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(), 
)); 
} 
}   
}
