Question

我使用CraueFormFlowBundle创建了一个多页表单。使用此表单，我可以创建新的实体对象或编辑现有对象。

然后我添加了设置

protected $allowDynamicStepNavigation = true;

允许在表单页面中来回导航，但是当使用表单编辑现有对象时，我希望能够直接跳转到表单中的任何页面。这似乎不起作用 - 对象数据已加载，我可以反复按下，直到我到达所需的页面有没有办法在使用CraueFormFlowBundle进行编辑时呈现页面导航？

我的模板包括：

{% include 'CraueFormFlowBundle:FormFlow:stepList.html.twig' %}

创建导航。这是editAction：

    public function editDriverAction($id) {

    $em = $this->getDoctrine()->getManager();

    $formData = $em->getRepository('NewgtDriverBundle:NewgtDriver')->find($id);

    if (!$formData) {
        throw $this->createNotFoundException('Unable to find Driver.');
    }

    //$formData = new NewgtDriver(); // Your form data class. Has to be an object, won't work properly with an array.

    $flow = $this->get('newgtDriver.form.flow.createDriver'); // must match the flow's service id
    $flow->bind($formData);

    // form of the current step
    $form = $flow->createForm();
    if ($flow->isValid($form)) {
        $flow->saveCurrentStepData($form);

        if ($flow->nextStep()) {
            // form for the next step
            $form = $flow->createForm();
        } else {
            // flow finished
            $em = $this->getDoctrine()->getManager();
            $em->persist($formData);
            $em->flush();

            $flow->reset(); // remove step data from the session

            return $this->redirect($this->generateUrl('driver')); // redirect when done
        }
    }

    return $this->render('NewgtDriverBundle:Driver:new.html.twig', array(
        'form' => $form->createView(),
        'flow' => $flow,
    ));
}

In the source code我们看到流类必须覆盖方法loadStepDescriptions。

我的FromFlow类就像：


namespace MyBundle\Form\Proposal;

use Craue\FormFlowBundle\Form\FormFlow;

class ProposalFlow extends FormFlow {

    protected $maxSteps = 5;

    protected $allowDynamicStepNavigation = true;

    protected function loadStepDescriptions() {
        return array(
            'Name',
            'Contract',
            'Filter',
            'Alternative',
            'Summary',
        );
    }
}

希望这个帮助
