Symfony2 - How to set, and get, options when using a Form Class?

Question

I am using Form Classes to build the various form in my project.

In the Entity Type file, for the buildForm function, there is a secondary parameter of \"array $options\

I think you're not setting them properly in the first place. You're supposed to give them as third argument to createForm()

EDIT: Here is how your form class could look:

add('name')
            ->add('slug')
            ->add('reference')
            ->add('description')
            ->add('active_from')
            ->add('active_till')
            ->add('is_active')
            ->add('category', 'entity', array(
                'class' => 'DEMO\DemoBundle\Entity\Product\ProductCategory',
                'query_builder' => function(EntityRepository $er) use($options) {
                    return $er->createQueryBuilder('u')
                        ->where('u.section = :id')
                        ->setParameter('id', $options['id'])
                        ->orderBy('u.root', 'ASC')
                        ->addOrderBy('u.lft', 'ASC');
                },
                'empty_value' => 'Choose an option',
                'property' => 'indentedName',
            ));
    }

    public function getDefaultOptions()
    {
        return array(
            'data_class' => 'DEMO\DemoBundle\Entity\Product\Product',
            'id'         => null
        );
    }

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