Question

我在我的控制器中定义了表单并将函数设置为 edit/update 我可以通过 ID 找到的特定字段。我找不到我做错了什么..

 public function getUserEdit(Request $request)
{
    $form = $this->createFormBuilder()
        ->add('firstName', TextType::class, array('label' => 'First Name*', 'attr' => ['class'=>'form-control']))
        ->add('save', SubmitType::class, array('label' => 'Send', 'attr' => [
            'class' => 'btn btn-primary action-save'
        ]))
        ->getForm();

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {

        $data = $form->getData();
        $firstName = $data['firstName'];

        $this->container->get('user')->editUser($firstName);
    }

    return $this->success();
}

服务

public function editUser($id)
{
    $editUsers = $this->getUserRepository()->find($id);

    if(empty($editUsers)) {
        $editUsers = new User();
        $editUsers->setId($id);
        $this->em->persist($editUsers);
        $this->em->flush();
    }
}

Symfony returns 单个对象当通过 find 主键搜索时（通常 id），然后你可以检查是否存在 returns 单个 Entity（在本例中为 User），因此使用 insteance.

进行检查

public function editUser($id)
{
    $editUsers = $this->getUserRepository()->find($id);

    if($editUsers insteance User) { // here just check 
        //$editUsers = new User(); // here You don't need create new object of class User, just remove
        $editUsers->setId($id);
        $this->em->persist($editUsers);
        $this->em->flush();
    }
    else {
        // do something if you need
    }
}
