For Slim v3.x:

Use $response->withStatus(302)->withHeader('Location', $url); instead of $app->redirect();

In Slim v2.x one would use the helper function $app->redirect(); to trigger a redirect request. In Slim v3.x one can do the same with using the Response class like so (see the following example)[1].

Use pathFor() instead of urlFor():

urlFor() has been renamed pathFor() and can be found in the router object. Also, pathFor() is base path aware[2].

Example:

$app->get('/', function ( $request, $response, $args ) use ( $app ) {
  $url = $this->router->pathFor('loginRoute');
  return $response->withStatus(302)->withHeader('Location', $url);
});

Note: additional parameters can be supplied by passing an associative array of parameter names and values as a second argument of pathFor() like: $this->router->pathFor('viewPost', ['id' => 1]);.

The router’s pathFor() method accepts two arguments:

1. The route name
2. Associative array of route pattern placeholders and replacement values[3]
