If you're looking for a bit easier and faster solution than suggested in answer above, here's how:

<?php// ...use Symfony\Component\Form\AbstractType;use Symfony\Component\Form\FormBuilder;use Symfony\Component\OptionsResolver\OptionsResolver;class MyType extends AbstractType{    // ...   public function configureOptions(OptionsResolver $resolver)    {        $resolver->setDefaults(array(            'csrf_protection' => false,        ));    }}

.. or if you're using older versions (Symfony 2.0.*):

<?php// ...use Symfony\Component\Form\AbstractType;use Symfony\Component\Form\FormBuilder;class MyType extends AbstractType{    // ....    public function getDefaultOptions(array $options)    {        $options = parent::getDefaultOptions($options);        $options['csrf_protection'] = false;        return $options;    }}

Consult the Symfony documentation for additional information.

Using the form factory

For those who want to create a simple form in a controller:

$form = $this->container->get('form.factory')    ->createNamedBuilder(null, 'form', null, array('csrf_protection' => false))    ->add('yourField','text', array(        'label' => false,        'mapped' => false    ))    ->getForm();

public function configureOptions(OptionsResolver $resolver){    $resolver->setDefaults([        'csrf_protection' => false,    ]);}
