symfony2 : Get form errors in controller

Question

I validated my form through AJAX CALL but can't retrieve "error messages".

Here is what i put :

$newRdvForm = $this->createForm(new RdvType());

$newRdvForm->handleRequest($request);

if ($newRdvForm->isValid()) { 
   // set of instructions to be performed when the form is valid
}
else {

   $errors= array();

   foreach ($newRdvForm->getErrors() as $key => $error) {
        $errors[$key] = $error->getMessage();
   }   

   $response = new Response(json_encode($errors));
   $response->headers->set('Content-Type', 'application/json');

   return $response; 

}

I used symfony 2.7. The above code doesn't retrieve the error messages.

Solution 1

Maybe Your for myte is builded from multiple nested types? Try to use getErrors(true)

http://symfony.com/doc/current/components/form/introduction.html#accessing-form-errors

Solution 2

/**
 * get Error Messages From Form.
 * @param \Symfony\Component\Form\Form $form
 * @return array
 */
protected function getErrorMessages(\Symfony\Component\Form\Form $form) {
  $errors = array();
 if ($form->count() > 0) {
    foreach ($form->all() as $child) {
        if (!$child->isValid()) {
           $errors[$child->getName()] = (String) $form[$child->getName()]->getErrors();
        }
     }
 }
 return $errors;
}
