在一個典型的用戶管理管理（Symfony3），這個工程：
// src/AppBundle/Form/UserType.php
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
// By default, password is required (create user case)
$passwordOptions = array(
'type' => PasswordType::class,
'first_options' => array('label' => 'Password'),
'second_options' => array('label' => 'Repeat password'),
'required' => true
);
// If edit user : password is optional
// User object is stored in $options['data']
$recordId = $options['data']->getId();
if (!empty($recordId)) {
$passwordOptions['required'] = false;
}
$builder
->add('prenom', TextType::class, array('label' => 'First name'))
->add('nom', TextType::class, array('label' => 'Last name'))
->add('email', EmailType::class)
->add('username', TextType::class)
->add('plainPassword', RepeatedType::class, $passwordOptions)
->add('roleList', ChoiceType::class, array(
'label' => 'Role',
'choices' => array(
'Admin' => 'ROLE_ADMIN',
'User' => 'ROLE_USER'
),
))
->add('save', SubmitType::class, array(
'attr' => array('class' => 'button-link save'),
'label' => 'Validate'
));
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\User',
));
}
}
不要忘記，以消除plainPassword @assert \ NotBlank（）在你的用戶實體：
/**
* @Assert\Length(max=4096)
*/
private $plainPassword;
我editAction（）在UserController.php：
/**
* @Route("https://stackoverflow.com/users/edit/{id}", name="user_edit")
*/
public function editAction($id, Request $request) {
// get user from database
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository('AppBundle:User')->find($id);
// user doesn't exist
if (!$user) {
throw $this->createNotFoundException('No user found for id '. $id);
}
// build the form with user data
$originalPassword = $user->getPassword(); # encoded password
$form = $this->createForm(UserType::class, $user);
// form POST
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// Encode the password if needed
# password has changed
if (!empty($form->get('plainPassword')->getData())) {
$password = $this->get('security.password_encoder')
->encodePassword($user, $user->getPlainPassword());
$user->setPassword($password);
# password not changed
} else {
$user->setPassword($originalPassword);
}
$role = $form->get('roleList')->getData();
$user->setRoles(array($role));
// update the User
$em->flush();
// success message
$this->addFlash('notice', 'User has been updated successfully !');
// redirection
return $this->redirectToRoute('user');
}
// show form
return $this->render('users/form.html.twig', array(
'h1_title' => 'Edit user : ' . $user->getPrenom() . " " . $user->getNom(),
'form' => $form->createView()
));
}
現在，創建新用戶時需要密碼，但編輯密碼時不需要密碼。
你試着用[ NotBlank]（http://symfony.com/doc/current/reference/constraints/NotBlank.html）驗證？ –
