For example, if a user accesses a password protected area of your web application and you wish to be able to redirect them back to the same page after they log in, you may find this example useful:.

You can use an anonymous function, or Closure, as the destination that a route maps to. This function will be executed when the user visits that URI. This is handy for quickly executing small tasks, or even just showing a simple view:. While the add method is simple to use, it is often handier to work with multiple routes at once, using the map method.

Instead of calling the add method for each route that you need to add, you can define an array of routes and then pass it as the first parameter to the map method:. Any site that lives long enough is bound to have pages that move. You can specify routes that should redirect to other routes with the addRedirect method.

The first parameter is the URI pattern for the old route. The second parameter is either the new URI to redirect to, or the name of a named route. The third parameter is the HTTP status code that should be sent along with the redirect. The default value is which is a temporary redirect and is recommended in most cases:.

If you need to assign options to a group, like a namespace , do it before the callback:. You can also use a specific filter for a group of routes. This will always run the filter before or after the controller. This is especially handy during authentication or api logging:.

At some point, you may want to group routes for the purpose of applying filters or other route config options like namespace, subdomain, etc.

Without necessarily needing to add a prefix to the group, you can pass an empty string in place of the prefix and the routes in the group will be routed as though the group never existed but with the given route config options.
