How can I redirect users to a node in a form submission handler similarly to the following code?

In my form alter I have added an additional submit button:

$form['actions']['save_and_exit'] = array(
    '#type' => 'submit',
    '#value' => t('Save & Exit'),
    '#submit' => array('custom_submit'),
  );

function custom_submit(&$form, \Drupal\Core\Form\FormStateInterface 
  $form_state) {
    $syst‌​em_path = '/node/2';
    $url = \Drupal::service('path.alias_manager')->getAliasByPath($syst‌​em_path);
    $form_state->setRedirect($url);
}

Then I'm getting following error:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route "/mypage" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 190 of C:\wamp\www\www_assure_local_com\core\lib\Drupal\Core\Routing\RouteProvider.php).

where /mypage is the url alias of my /node/2.

A form submission handler never returns a RedirectResponse object to redirect users. (It actually doesn't return any value.)

A form submission handler calls FormState::setRedirect(), or FormState::setRedirectUrl() which accepts a Url object, for example the value returned from Url::fromUri('//my_node_url_alias').

  • Sorry.. I'm not clear on that. how could I put it submit function? like this $url = Url::fromUri('//my_node_url_alias'); FormState::setRedirectUrl($url); ?

    $url = \Drupal::service('path.alias_manager')->getAliasByPath($system_path, $langcode), where $system_path is "/node/$nid"

    Read api.drupal.org/api/drupal/… and api.drupal.org/api/drupal/…, you need to use one of those with the correct parameters

  • @ARUN Use $form_state->setRedirectUrl(Url::fromUri('//my_node_alias')).
