Symfony2 Ajax + Forms

Question

I use Symfony 2.6 (I know, deprecated soon). I want to create a web page that contains the same form 5 or 6 times (to create User) because one User can create limited numbers of others Users. So I can't use FormBuilder because you can't display several times. Then I created normals HTML Forms:

 <form class="fcrv" action="{{ path('path') }}" method="POST">
      <input type="text" name="Name" placeholder="Name"/>
      <textarea rows="4" cols="50" name="comm"></textarea> 
      <input type="submit" value="Validate">
 </form>

I Handle Form by Form with Ajax and I sent the data needed in my Controller. I can get data in Controller with :

$name = $request->request->get('Name');
$comm = $request->request->get('comm');

It's work. After this I want to Simulate the behavior of a normal Form. I need to create my new Form and put the data in, so I did :

//create a new User
$user = new User();
$user->setCreateDate(new Date());

//Create the form
$form = $this->createForm(new UserType(), $user);
$form->setData(array('name'=>$name));
$form->setData(array('comm'=>$comm));

$form->submit($request->request->get($form->getName()));

if ($form->isValid()) {
   //Some actions
}

My UserType :

<?php

 namespace Test\Bundle\Form;

 use Symfony\Component\Form\AbstractType;
 use Symfony\Component\Form\FormBuilderInterface;
 use Symfony\Component\OptionsResolver\OptionsResolverInterface;

 class UserType extends AbstractType
 {
     /**
      * @param FormBuilderInterface $builder
      * @param array $options
      */
     public function buildForm(FormBuilderInterface $builder, array $options)
     {
         $builder
             ->add('name', 'text')
             ->add('comm', 'text')
         ;
     }

     /**
      * @param OptionsResolverInterface $resolver
      */
     public function setDefaultOptions(OptionsResolverInterface $resolver)
     {
         $resolver->setDefaults(array(
             'data_class' => 'Cfau\CleBundle\Entity\FraisVisite',
             'csrf_protection' => false
         ));
     }

     /**
      * @return string
      */
     public function getName()
     {
         return 'test_bundle_user';
     }
}

And the conditions in entity User is just : @Assert\\NotBlank()

But the form isn't valid !

I disable CSRF token.

I use

 echo $form->getErrors(true, false);

to see what wrongs with my form and it say : name: ERROR: This value should not be blank. But I put data with $form->setData(array('name'=>$name)); !

Can you help me. Thanks !

If I understood correctly what you are trying to do, I think you should setData after submit , instead of before.

Also, be careful since you seem to use "name" in your FormBuilder but "Name" in your view (so maybe in your AJAX call as well). This might be the problem.
