Fuelphp - route index with parameters - fuelphp

Question

Using Fuelphp, I'd like to be able to use a URL system similar to here on StackOverflow to get to specific pages.
Desired behavior:
-stackoverflow.com/questions -> page with many questions
-stackoverflow.com/questions/1982 ->page with specific question
Here's my controller:
class Controllers_Images extends Controller_Template
{
public function action_index($id=null)
{
if($id)
{
//Use Model_Image to find specific image
//Create appropriate view
}
else
{
//Use Model_Image to find many images
//Create appropriate view
}
}
}
I can access the "generic" page with mysite.com/images/ - this is routed to the action_index function. I can access a "specific" page with mysite.com/images/index/1. What I'd like to do is be able to skip index in this case too, so that mysite.com/images/1 works. Right now I'm getting 404. How do I set up routing for this?

Answer 1

After poking around a bit more, I came up with a solution that works fine:
class Controllers_Images extends Controller_Template
{
public function action_index()
{
//Use Model_Image to find many images
//Create appropriate view
}
public function get_id($id)
{
//Use Model_Image to find specific image
//Create appropriate view
}
}
In routes.php:
return array(
'images/(:num)'=>'images/id/$1',
//other routing stuff...
);
With this setup, the url "mysite.com/images/1" now appropriately displays the selected image as if "mysite.com/images/id/1" was used instead. Not a huge deal, but it is a nicer interface, which is important!
