Form handlers

Form handler interface

The mission of Form Handlers is to encapsulate CrUD business operations into one proccessor class.

All the forms must be validated, then some action must be done with contained data, and usually those actions are duplicated.

With the use of form handlers all those actions are in one method, and can be called anywhere.

Doctrine Create form handler

Handler for creating doctrine entities in a CRUD controller.

Example

/**
 * @param Request $request
 *
 * @return Response
 */
public function createAction(Request $request)
{
    $element = new Element();

    $form = $this->createForm(new ElementType(), $element);

    if ($this->get('create_form_handler')->process($form, $request)) {
        return $this->redirectToRoute('success_route', ['element', $element->getId()]);
    }

    $viewData = [
        'form' => $form->createView(),
    ];

    return $this->render('ExampleBundle:Element:create.html.twig', $viewData);
}

Doctrine Update form handler

Handler for updating doctrine entities in a CRUD controller.

Example

/**
 * @param Element $element
 * @param Request $request
 *
 * @return Response
 */
public function updateAction(Element $element, Request $request)
{
    $form = $this->createForm(new ElementType(), $element);

    if ($this->get('update_form_handler')->process($form, $request)) {
        return $this->redirectToRoute('success_route', ['element', $element->getId()]);
    }

    $viewData = [
        'element' => $element,
        'form' => $form->createView(),
    ];

    return $this->render('ExampleBundle:Element:update.html.twig', $viewData);
}

Doctrine Delete form handler

Handler for deleting doctrine entities in a CRUD controller.

Example

/**
 * @param Element $element
 * @param Request $request
 *
 * @return Response
 */
public function deleteAction(Element $element, Request $request)
{
    $form = $this->createForm(new ElementType(), $element);

    if ($this->get('delete_form_handler')->process($form, $request)) {
        return $this->redirectToRoute('success_route');
    }

    $viewData = [
        'element' => $element,
        'form' => $form->createView(),
    ];

    return $this->render('ExampleBundle:Element:delete.html.twig', $viewData);
}
