Question

当我尝试创建一个from without form builder class

时，我收到此错误

错误：属性＆＃34; date_evenement＆＃34;也没有其中一种方法＆＃34; getDateEvenement（）＆＃34;，＆＃34; dateEvenement（）＆＃34;，＆＃34; isDateEvenement（）＆＃34;，＆＃34; hasDateEvenement（）＆＃ 34;，＆＃34; __ get（）＆＃34;在课堂上存在并具有公共访问权限＆＃34; Upm \ GeneralBundle \ Entity \ Evenement＆＃34;。

我确信我的Evenement Entity课程中的所有内容都是正确的，但我无法找到错误。

我的表单函数ajouterEvenementAction（Request $ request）是这样的：

$evn = new Evenement();
    $form = $this->createFormBuilder($evn)
->add('date_evenement',TextType::class,array('attr'=>array('class'=>'form-control pull-right','style'=>"width: 100%;",'palceholder'=>'JJ/MM/AAAA')))
->add('heure',TextType::class,array('attr'=>array('class'=>'form-control pull-right','palceholder'=>"hh:mm")))->add('fichier',FileType::class,array('attr'=>array('style'=>'display: none;','class'=>'file')))
->add('objet',TextType::class,array('attr'=>array('class'=>'form-control')))
->add('description',TextareaType::class,array('attr'=>array('class'=>'form-control')))
->add('Responsable_evenement',TextType::class,array('attr'=>array('class'=>'form-control')))
->add('Ajouter',SubmitType::class,array('label'=>"Ajouter l'Evenement",'attr'=>array('class'=>'form-control  btn btn-success')))->getForm();

$form->handleRequest($request);

    if($form->isSubmitted())
    {
        $dateEvent = $form->get("date_evenement");
        $heuerEvent = $form['heure']->getData();
        $nomFichier = date('Ymd').''.date('gisa').'.'.$form['fichier']->getData()->guessExtension();
        $imageEvent =$nomFichier;
        $objetEvent = $form['objet']->getData();
        $descEvent = $form['description']->getData();
        $Responsable_evenement = $form['Responsable_evenement']->getData();

        $evn->setDate_evenement($dateEvent)
            ->setHeure($heuerEvent)
            ->setFichier($imageEvent)
            ->setObjet($objetEvent)
            ->setDescription($descEvent)
            ->setId_user($this->get('security.token_storage')->getToken()->getUser()->getId())
            ->setResponsable_evenement($Responsable_evenement);

        $file = $form->get('fichier')->getData();
        $name =$nomFichier;
        $dir = __DIR__.'/../../../../src/Upm/GeneralBundle/Resources/public/Uploads';

        $file->move($dir, $name) ;

        $em = $this->getDoctrine()->getManager();
        $em->persist($evn);
        $em->flush();
        return $this->redirectToRoute('home_page_admin');}

感谢帮助人员。

Answer 1

您将自己的名字命名为

public function getDate_evenement()

虽然Symfony的表单组件希望您将它们命名为：

public function getDateEvenement()

无论如何这是一种标准的方法。

你应该重构你的实体，以经典的方式命名getter。

顺便说一句，你的惯例非常奇怪。

Answer 2

Symfony2表单组件需要使用方法：getDateEvenement来获取$date_evenement属性的默认值。相反，你有getDate_evenement形式知道nothig。

财产＆＃34; date_evenement＆＃34;也不是其中一种方法＆＃34; getDateEvenement（）＆＃34;
