如何在Sonata Admin Bundle中实施Ajax表单验证？

Question

I am newbie in Symfony. I use Sonata Admin Bundle Symfony 2.1. How can I implement Ajax Form Validation? Are there any solutions?

I'm not sure if that works in Sonata Admin 2.1 but you can try the following if you have for example a *sonata_type_collection*. Set the option: 'cascade_validation' => true that should do the job.

That works quite fine at current Sonata Admin (2.3).

$formMapper
         ->with('customer_contacts', array('collapsed' => true))
            ->add('customer_has_contacts', 'sonata_type_collection', array('cascade_validation' => true), 
                array(
                    'edit'              => 'inline',
                    'inline'            => 'table',
                    'sortable'          => 'position',
                    'admin_code'        => 'acme_demo_bundle.customer_has_contacts',
                )
            )
        ->end();
