## Linking to a controller
Return the link for this Controller. Should return a value that makes sense with your custom route.
Each controller has a built-in `Link()` method,
which can be used to avoid hardcoding your routing in views etc.
The method should return a value that makes sense with your custom route (see above):
:::php
<?php
class FastFood_Controller extends Controller {
public function Link() {
return 'fastfood';
public function Link($action = null) {
return Controller::join_links('fastfood', $action);
}
}
The [api:Controller::join_links()] invocation is optional, but makes `Link()` more flexible
by allowing an `$action` argument, and concatenates the path segments with slashes.
The action should map to a method on your controller. `join_links()` also supports
