Custom module: redirect() to page in CP

Hey everyone!

Building a small module with a backend control panel using ExpressionEngine v2.1.0 Build 20100810.

I’m having issues redirecting users to the module’s index page in CP.

Here is a snippet I’ve been trying:

$uri = BASE.AMP.'C=addons_modules'.AMP.'M=show_module_cp'.AMP.'module=rollen';
$uri = html_entity_decode($uri);
redirect($uri);

redirect() seems to always redirect to /index.php, so whatever I make out $uri to be, I get redirected to somewhere outside of CP.

An example would be:

http://hostname.example.com/index.php/index.php?S=22e3308a58a571e3386aa2aac43a227a11b54321&D=cp&C=addons_modules&M=show_module_cp&module=rollen

That URI needs to be:

http://hostname.example.com/cms/index.php?S=22e3308a58a571e3386aa2aac43a227a11b54321&D=cp&C=addons_modules&M=show_module_cp&module=rollen

I can use this for redirect and still end up outside of CP:

redirect('/cms/'.$uri);

is redirected to

http://hostname.example.com/index.php/cms/index.php?S=22e3308a58a571e3386aa2aac43a227a11b54321&D=cp&C=addons_modules&M=show_module_cp&module=rollen

Again: http://hostname.example.com/index.php added to the URL I need.

Can anybody shed some light on this issue? Did I miss something in the User Guide?

Thanks!… Nico
