Change structure in the CI

[eluser]Unknown[/eluser]
Hello everybody,

I was asked to change structure in the CI, it like this:


In each controller, each with its own directory , each directory has the file controller.
- Normally, each time when running, we call to directory that contains the file Controller, then calling Class controller and Method, ...
- And now just call an alias , it is self-understanding is pointing to any directory, any class . (Each alias will replace a directory, a class)

Example: Suppose there Listtype folder (directory Controller), including file Category (category.php).

=> call in the normal way :

http://localhost/demo/index.php/listtype...ry/method/

And just call "alias"

http://localhost/demo/index.php/alias/method /

In it, "alias" will replace listtype / category. I have used in the configuration file (route.php) but not correct

$route['alias/(:num)'] = "listtype/category/$1";

But I think it doesn't work all cases (as if there are more variables in each segment, ...)
Please help me solve this problem, thanks very much

Sorry my English.
