malwarebytes/form-metadata-bundle

Use annotations with the forms builder e.g. @Form\Field("text"). Associates metadata along with the entity class. Useful to make more generic controllers that can deal with dynamic entities (such as CMS scenarios).

README

Facilitates the basic configuration of form fields from metadata that is defined elsewhere, such as through annotations in the entity. 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).

This project was forked from FlintLabs/FormMetadataBundle which appears to be abandoned.

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")
 */

Group Example

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

Embedded Entity Example

/**
 * Refer to http://symfony.com/doc/current/book/forms.html#embedded-forms
 *
 * You have to generate your own FormType in current implementation
 *
 * @Form\FormType("Acme\TaskBundle\Form\Type\CategoryType")
 */

Entity with some basic form annotations

use Malwarebytes\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') {
            $form->bindRequest($request);

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