Symfony2 Form Component - creating fields without the forms name in the name attribute

Question

I\'m currently trying to use the Symfony2 Form Component though the Silex microframework.

My login form is generated as follows:

$app = $this->app         


        

Answer 1

If you are not using child forms you can set getName method of your form as empty string:

class FormType extend AbstractType {
    // ...

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

Answer 2

In Symfony3, override AbstractType::getBlockPrefix in child class to return null.

Answer 3

Instead of the createBuilder function use:

$builder = $app['form.factory']->createNamedBuilder(null, 'form', $data, array('validation_constraint' => $constraint));

First parameter being the form name.
