How to validate form without entity in controller? - php

Question

I have a basic form to send an email :
<form action="{{ path('user_send_mail') }}" method="post" enctype="multipart/form-data">
<input name="email_to" type="email" class="form-control" placeholder="To" required>
<input name="email_cc" type="email" class="form-control" placeholder="Cc">
<textarea name="message" id="email_message" class="form-control" placeholder="message" style="height: 120px;" required></textarea>
<input type="file" name="attachment"/>
<p class="help-block">Max. 2MB</p>
<button type="submit" class="btn btn-primary pull-left"><i class="fa fa-envelope"></i> Send the email</button>
</form>
And an action in my controller to validate the data and send the mail but validation doesn't work..
use Symfony\Component\Validator\Constraints\Email;
use Symfony\Component\Validator\Constraints\File;
use Symfony\Component\Validator\Constraints\NotBlank;
public function sendMailToUserAction(Request $request)
{
$form = $this->createFormBuilder(null)
->add('email_to', 'email', array(
'required' => true,
'constraints' => new Email()
))
->add('email_cc', 'email', array(
'required' => false,
'constraints' => new Email()
))
->add('message', 'textarea', array(
'required' => true,
'constraints' => new NotBlank()
))
->add('attachment', 'file', array(
'required' => false,
'constraints' => new File()
))
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
$data = $form->getData();
var_dump($data);exit;
} else {
var_dump("error");exit;
}
}
When I submit the form, I got always "error", so validation doesn't work but I don't know why... I have read a lot of topics about this but I get stuck..
EDIT : If I print form error using $form->getErrorsAsString() instead of var_dump("error");exit;, I got this :
string(97) "email_to: No errors email_cc: No errors message: No errors attachment: No errors "

please reffer to this: http://symfony.com/doc/current/book/forms.html#using-a-form-without-a-class it think you have to pass array with fields name that you want to validate (its like a default values)
p. s. why not using Simple PHP Object for that? Symfony2 forms fields name should contain brakets like (for example): data[email_to] instead of email_to
