Problem/Motivation

I want to create a form which redirects after submit. I want to use the "post book" example as a model. However, the redirect in the "post book" example has no effect.

Steps to reproduce

  1. Create a fresh Drupal install
  2. Install Multistep Form Framework and Multistep Form Framework Examples
  3. Open /post-book.
  4. Complete steps, entering data into each field
  5. On the "Congratulations" page, select the "Go Back to Site" button"

Result

Expected: Return to the front page.
Actual: Remain on the "Congratulations" page.

I've been able to get this to work by taking the following steps.

  1. Override the ajax callback function inside Congratulation.php: 
        protected function getSubmitButton(): array
    {
        $button = parent::getSubmitButton();
        $button['#value'] = $this->t("Go back to site.");
        $button['#ajax']['callback'] = '::ajaxRedirectOnSubmit';
        $button['#ajax']['event'] = 'click';
        return $button;
    }

    function ajaxRedirectOnSubmit()
    {
        $response = new AjaxResponse();

        $url = Url::fromRoute('<front>');
        $command = new RedirectCommand($url->toString());
        $response->addCommand($command);

        return $response;
    }
  2. Adjust the getActions method of BaseStep to not reset the ajax callback which I've now overridden. 
            if ($this->wizard->isAjaxEnabled()) {
            foreach (Element::children($actions) as $child) {
                // do not set ajax if it is already set (i.e., overridden)
                if (!isset($actions[$child]['#ajax'])) {
                    $actions[$child]['#ajax']['callback'] = '::ajaxSubmit';
                    if (isset($form['#id'])) {
                        $actions[$child]['#ajax']['wrapper'] = $form['#id'];
                        $actions[$child]['#ajax'] += $this->getDefaultAjaxOptions();
                    }
                }
            }
        }

Hope this helps.
