Symfony form submits wrong data - php

Question

In Symfony I have this part of my code where I am building a view with some data and a form with some radio buttons. When submitting the form I am doing a dump in the view to check which data has been submitted, but the data does not match with the one the form was build. Can someone help? Thanks.
public function playAction(Request $request){
$data = $this->getDbQuestion();
$questionData = $data[0];
dump($questionData);
$answerData = $data[1];
dump($answerData);
$form = $this->createFormBuilder($answerData)
->add('answers', ChoiceType::class,
array(
'choices'=> $answerData,
'multiple'=>false,'expanded'=>true,
'choice_label' => 'answer',
))
->add('Submit',SubmitType::class, array('label' => 'Send Answer'))
->getForm();
$form->handleRequest($request);
if($form->isSubmitted()) {
$formData = $form->getData();
return $this->render('QuizViews/correctAnswer.html.twig', array(
'ss' => $formData
));
}
return $this->render('QuizViews/playQuiz.html.twig', array(
'form' => $form->createView(),
'question' => $questionData
));
}
Twig
<a href="/quiz/question">
<input type="button" value="Start Quiz" />
</a>

FormData Correct {{ dump(ss) }}

Answer 1

After chatting, this might be a better solution for the answer section:
->add('answers', EntityType::class, array(
'class' => 'AppBundle:Answer',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('a')
->where('a.question_id->getId() = :qID')
->setParameter('qID', 1);
},
'multiple'=>false,
'expanded'=>true,
'choice_label' => 'answer',
))
Try it!

Answer 2

Your call to get the data after verifying the form isSubmitted is incorrect. You need to call like so:
$formData = $form->get('answers')->getData();
That just gets the 'answers' only.
Edit #2
You might also want to change this:
->add('answers', ChoiceType::class,
array(
'choices'=> $answerData,
'multiple'=>false,
'expanded'=>true,
'choice_label' => 'answer',
'choice_value' => $answerData,
))
Which sets the 'choice_value', what is actually selected and returned from the getData().
Can you post your twig answers file please? Edit your post and so I can see.
