problem with routing and passing arguments

[eluser]murichej[/eluser]
i want to acces to archive controller, which is in folder "front". for example: archive/2013/05

so i got this:

routes.php:

$route['archive/(:num)/(:num)'] = "front/archive/$1/$2";

controller front/archive.php:

1.

public function index()

it's working but need to access to arguments via uri->segment()


2.

public function index($a)

it's working but obviously i get only first parameter


3.

public function index($a, $b)

i get an error: "Message: Missing argument 2 for Archive::index()"


i have no idea what is happening. 3rd choice should work in my opinion. i can't understand why 2nd choice is working but 3rd doesn't.

In your route, try including the index method.

Code:

$route[‘archive/(:num)/(:num)’] = “front/archive/index/$1/$2”;

[eluser]murichej[/eluser]
tried. if I do this I don't even get 1st argument

Try using a different method other than index. Index is meant to be used when NO parameters are sent, including the method name.
