Routing optional paremeter

[eluser]Jagar[/eluser]
How can I make a parameter optional in routing.

For example I have the following link

Code:

admin/admin_manage/index/(optional param}

into this

Code:

admin/manage/(optional param)

I'm doing the following:

Code:

$route['admin/manage/?(:any)'] = 'admin/admin_manage/$1';

but does not work

Thanks

I'm using

Code:

$route['admin/manage/?(.*)'] = 'admin/admin_manage/index/$1';

and in my index function i have a parameter function index($sortby='id') which is optional, that will be used if nothing is there.

But with that routing code, it seem to delete the default param for function index.

Any ideas?

Thanks for any help!

I got it working and may not be the best way.

In my function where I receive the sort by, I check if the field exist and if it exist. If any of those are false, then I set to default.
