Symfony 2.6 form validation and error messages

Question

I am fairly new to Symfony. I have written the below code to validate and return error messaged if validation failed. But I was able to only get the error message not the field which failed the validation. Below is my code:

if ($request->isXmlHttpRequest()) {

        if ($form->isValid()) {
            //do something here
        }

        $errors = $this->get('my_form')->getErrorMessages($form);
        return new JsonResponse(['errors' => $errors], 400);
}

Can someone please tell me how can I also get the field name along with the error message.

Thanks

In order to get all the Errors of a form use $form->getErrors($deep=true, $flatten=true) so converting the errors to an array with names as field names and keys as messages will be something like:

$errors = $form->getErrors(true, true);
$errorArray = array();
foreach($errors as $e){
  //get the field that caused the error
  $field = $e->getOrigin();
  $errorArray[$field->getName()] = isset($errorArray[$field->getName()]) ? $errorArray[$field->getName()] : array();
  $errorArray[$field->getName()][] = $e->getMessage();
}
