Question

I am trying to add some validation for my registration form, but i can’t get it to work, so far i have added my User entity

Snippet.

class User {

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
   protected $userid;

/**
 * @ORM\Column(type="string", length=30)
 */
 protected $username;

For this i’ve added a validation.yml to my bundle.

# src/Blomster/UserBundle/Resources/config/validation.yml

Blomster/UserBundle/Entity/User:
    properties:
        username:
            - NotBlank: ~
            - MinLength: { limit: 3, message: "Username is too short." }
            - MaxLength: { limit: 15, message: "Username is too long." }

Using $form->isValid() always return true, so i tried to var_dump my form

      'validation_groups' => null
      'validation_constraint' => null
      'constraints' => 
        array (size=0)
          ...

The form itself is working great, it adds to my data base when submitted, do i need to add the constraints to the form somehow?

Added UserType.php

class UserType extends AbstractType {

  public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder->add('username', null, array('label' => 'Username'));
    $builder->add('email', 'email', array('label' => 'Email'));
    $builder->add('password', 'repeated', array(
        'type' => 'password',
        'required' => true,
        'first_options' => array('label' => 'Password'),
        'second_options' => array('label' => 'Repeat password'),
      ));
  }

  public function getDefaultOptions(array $options) {
    return array('data_class' => 'Blomster\UserBundle\Entity\User');
  }

  public function getName() {
    return 'user';
  }
}

You need to use a length limit :

        - MinLength: { limit: 3 }
        - MaxLength: { limit: 15 }

here is the documentation.

In fact : you need to specify a limit because you can also set other options like a message and so on.
