Facilitates the basic configuration of form fields from metadata that is defined elsewhere, such as through annotations in the entity or with an external yaml file (TODO). Allows for more generic handling of form types through controllers, making them able to deal with dynamic entity/forms (such as for use with CMS sites).

See the form fields Annotations Reference

Note: People may want to consider the use of Symfony2 Abstract Forms to configure their forms external to the controller as a best practice.

Annotations Example

Standard form builder

->add('dueDate', 'date', array('widget' => 'single_text'))

Using annotations in your entity

 * @Form\Field("date", widget="single_text")

Entity with some basic form annotations

use FlintLabs\Bundle\FormMetadataBundle\Configuration as Form;
use Symfony\Bundle\Validator\Constraints as Assert;

class Contact
     * @Form\Field("text")
     * @Assert\NotBlank()
    public $name;

     * @Form\Field("textarea")
    public $message;

Simple controller

class MyController
    public function contactAction()
        $contact = new Contact();
        $form = $this->get('form_metadata.mapper')->createFormBuilder($contact)->getForm();

        if ($request->getMethod() == 'POST') {

            if ($form->isValid()) {
                // perform some action, such as saving the task to the database
                return $this->redirect($this->generateUrl('task_success'));
