I'm trying to override the SonataUser/Admin/Model/UserAdmin 's configureFormFields() because I need to remove some default fields from the admin form. So I have copied the file vendor/bundles/Sonata/UserBundle/Admin/Model/UserAdmin.php in my bundle app/Application/Sonata/UserBundle/Admin/Model/UserAdmin.php and modified it.

问题 Here is my FormType : public function buildForm(FormBuilder $builder, array $options) { $builder ->add('user', 'entity', array( 'class' => 'UserBundle:User', 'expanded' => true, 'property' => 'name', )); } Is there a way to access user's fields in the view (Twig) ?

How can I check whether the supplied CSRF token is invalid in Symfony2?

阅读更多关于 How can I check whether the supplied CSRF token is invalid in Symfony2?

I have created a Symfony2 form and bound it to the Request. I need to explicitly ensure whether the CSRF token is valid/invalid before proceeding with the rest of the form. $form['_token']->isValid() throws OutOfBoundsException with message "Child _token does not exist." I can still verify that the rendered form contains _token field. In case that CSRF value is invalid, $form->isValid() returns false. What am I missing here? Update 1: Controller (partial): private function buildTestForm() { $form = $this->createFormBuilder() ->add('name','text') ->getForm(); return $form; } /** * @Route("/test

How to 'validate' a Symfony form in steps - instead of calling $form->isValid()

问题 I am using Symfony 1.3.6 on Ubuntu. I have a form with a lot of fields on it - rather than showing all the fields in one go (which may intimidate the user), I want to break up the form into stages, so that a user can fill in only the fields displayed, at each step/stage (kinda like a wizard). In order to do that, I need to write custom methods for the form, e.g.: validateStep1(); validateStep2(); ... validate StepN(); Where in each of the functions above, I only validate a subset of the
