Symfony2：$ form-> isValid（）始终为true

Question

I have problem with form validation in Symfony2:

part of form class:

class CompanyType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options){
        $builder
            ->add('name', 'text',array("label"=> "Nazwa",'max_length' => 255, 'required'=>true))
            ->add('url', 'url',array("label"=> "Adres strony",'max_length' => 255, 'required'=>true))
            ->add('logo', 'file',array("label"=> "Logo",'max_length' => 255))
            ->add('Dodaj', 'submit');
    }
    public function setDefaultOptions(OptionsResolverInterface $resolver){
        $resolver->setDefaults(array(
            'data_class' => 'Diliges\DiligesBundle\Entity\Company',
            'error_bubbling' => true
        ));
    }
}

part of Controller method:

public function addAction(Request $request){
        $company = new Company();
        $form = $this->createForm(new CompanyType(), $company);
        $form->handleRequest($request);

        if ($form->isValid()) {

            try{
                $company->setActive(false);
                return $this->redirect($this->generateUrl('add_company_thx'));
            }catch(PDOException $e){

            }

        }
        ...

Company entity

properties:
        name:
          - NotBlank: ~
          - MinLength: 3
        url:
          - NotBlank: ~

Im trying, and trying, and still $form->isValid() return true, always. Even when I submit empty form.

Answer 1

You must have your validation configuration in the wrong spot. Look at the docs for where the yml config is placed. Basics of Validation

They put the config file in src/Acme/BlogBundle/Resources/config/validation.yml. Also, your format of the config is not correct. You are missing the entity definition.

Diliges\DiligesBundle\Entity\Company:
    properties:
        name:
          - NotBlank: ~
          - MinLength: 3
        url:
          - NotBlank: ~

Another option that could be making this not work is if you have enabled a different kind of validation (like annotations). Make sure yml is enabled
