Redirect to controller specific function w/parameters

[eluser]chitoso[/eluser]
Hi guys, this is my first time here. I've been learning CI for a quick project. It's been a couple of days now and I think it was a great choice so far.

Anyway, I have a specific doubt that couldn't solve in this few days.

In my routes.php:

Code:

$route['admin/pages/edit/(:num)'] = 'admin/admin/edit_page/$1';

On my Admin Controller I have the function:

Code:

function edit_page($page_id) {
...

}

And in some point in edit_page I I'm doing some redirects like: redirect('admin/pages/edit/' . $page_id)

But, I'd feel it much more natural to do this: redirect('admin/admin/edit_page/', $page_id). This way, URLs wouldn't have to be so coupled in the code.

Is the first usage the way we're supposed to do this or am I missing something?

Thanks!
