Symfony2 FormType转换为JSON

Question

Is it possible somehow to serialize Symfony2 FormType into JSON? I have the following Type for User form.

class UserType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name', 'text', array('label' => 'Name'))
            ->add('surname', 'text', array('label' => 'Surname'))
            ->add('username', 'text', array('label' => 'Username'))
            ->add('email', 'text', array('label' => 'Email'))
            ->add('isAdmin', 'checkbox', array('label' => 'Admin'));
    }
    ...
}

Possible to get the following or similar JSON format using Symfony2 itself, or I will need my custom parser?

{
    "name": {
        "type": "text",
        "label": "Name"
    },
    "surname": { 
        "type": "text",
        "label": "Surname"
    },
    "username": {
        "type": "text",
        "label": "Username"
    },
    "email": {
        "type":"text",
        "label":"Email"
    },
    "isAdmin": {
        "type": "checkbox",
        "label" : "Admin"
     }
}

Answer 1

You could implement a form theme that would output your widgets any way you want to. Here's a link to Symfony documentation that explains how to create and apply form themes.

However, if you're implementing an API (otherwise why would you need to get the form as JSON?), you should definitely take a look at FOSRestBundle , as it implements form handling and serialization.

看起来您可能正在寻找类似Liform捆绑包的东西，该捆绑包允许您从Symfony表单生成JSON模式。
