URI Mapping to another controller

[eluser]Unknown[/eluser]
Hi, I wish to map the URI to another controller, however CI can only access the index() method, while calling other method in the mapped controller, it will give me a 404 error.

Example:

example.com/admin

Everything works as it is. there is a controller for "admin"）

But I wish to map the following URI to its controller.

Example:

Code:

example.com/admin/users

this would be mapped to "users" controller

But, so far CI would only show "users" controller's index() method to me.
but if I tried to access other functions defined in "users" controller (in this example : test() method)

Code:

example.com/admin/users/test

would result in a 404 error


here is my current Routes.php's configuration:

Code:

$route['admin/user'] = "user";
$route['default_controller'] = "admin/query";
$route['404_override'] = '';

Any help would be appreciated!
Thanks!
