Url component and helper

There is both a component and helper that help to work around some URL issues.

Defaults

If you need to merge in defaults to your URLs, you can get the information from the defaults() method:

// From inside a plugin controller action
$this->redirect(['controller' => 'Main', 'action' => 'index'] + $this->Url->defaults());

It will basically add in 'prefix' => false, 'plugin' => false.

Reset

You can in that case also just use the convenience method:

$url = $this->Url->buildReset(['controller' => 'Main', 'action' => 'overview']);

In case you just want the array (to pass it on), use:

// Inside an action
$urlArray = $this->Url->resetArray(['controller' => 'Main', 'action' => 'overview']);
return $this->redirect($urlArray);

Inside /admin/plugin-name/example/action the URL to redirect to would normally become /admin/plugin-name/main/overview. With the reset() method it will become the desired: /main/overview.

For the controller

Complete

In both cases, however, the query strings are not passed on. If you want that, you can use the other convenience method:

$url = $this->Url->buildComplete(['controller' => 'Main', 'action' => 'overview']);

In case you just want the array (to pass it on), use:

// Inside an action
$urlArray = $this->Url->completeArray(['controller' => 'Main', 'action' => 'overview']);
return $this->redirect($urlArray);

Now if there was a query string ?q=x on the current action, it would also be passed along as /main/overview?q=x.
