How to redirect programatically using a route with parameters?

Question

I am trying to use the Passwordless module API to redirect the user on login.

I want to redirect the user to a specific node edit page (node/12/edit).

In hook_passwordless_login_redirect(), the module redirects the user with this code:

return $this->redirect($redirect);

So here is my implementation:

function MYMODULE_passwordless_login_redirect_alter(&$redirect) {
  // You can use hasPermission() with currentUser, but need to load for hasRole()
  $account = \Drupal\user\Entity\user::load(\Drupal::currentUser()->id());
  $test = \Drupal::service('path.validator')->getUrlIfValid('node/12/edit');
  if (!($account->hasRole('admin'))) {
    $redirect= $test->getRouteName();
  }

The problem is that I get this error:

Some mandatory parameters are missing ("node") to generate a URL for route "entity.node.edit_form".

The missing route parameter is the node id, which I can get with $test->getRouteParameters(). But how do I pass this to the redirect? (How do I call the redirect and give it both the route name and the route parameters?)

Answer 1

As pointed out by @4k4, the problem is that the module did not ask for the route parameters, so I patched it.

Then you can call the redirect like this:

  if (!($account->hasRole('admin'))) {
    $routename = $test->getRouteName();
    $routeparameters= $test->getRouteParameters();
  }

Answer 2

You can pass parameters like below:

$url = \Drupal\Core\Url::fromRoute(
    $test->getRouteName(),
     array(
       'query' => array('query1' => 'YOUR QUERY'),
       'absolute' => TRUE,
     )
);
