Symfony表单生成器单选按钮

Question

I am using Symfony 3 framework, and I need to create a form that will display a quiz question, and image and four possible answers as radio buttons. So far I have created the fields id,question and image that are mapped to my entity fields from my database but having problem with the radio buttons. Bellow is what I have so far.

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
    $builder
        ->add('id',HiddenType::class)
        ->add('image',TextType::class)
        ->add('question',TextType::class)
        ->add('Options to choose',ChoiceType::class,
                array('choices' => array(
                        'answer1' => '1',
                        'answer2' => '2',
                        'answer3' => '3',
                        'answer4' => '4'),
                'choices_as_values' => true,'multiple'=>false,'expanded'=>true))
        ->add('Submit',SubmitType::class);
}

My problem are the following:

->add('Options to choose' I cannot have this, because Symfony is trying to find methods in my entity class. Also bellow 'answer1' => '1' is not getting the data from the database. How can I pull the data from the database and display it for each radio buttons. How can I solve this issues and have 4 radio buttons that display the 4 database options. Thanks for the help.

What you've done so far looks more like a form which will create a question.

Use entity field and choices options :

$builder->add('answer', EntityType::class, array(
'class' => 'AppBundle:Answer',
'choices' => $question->getAnswers(),

));

Your goal is to build a form with one question and its answers. Can you show us your entities ? Quiz, Question and Answer i guess.
