Unlikely question...

If you have something like "www.yoursite.com/admin" or "www.yoursite.com/index.php/admin" in the url you can just grab the controller name using the URI Class:

Code:

if ($this->uri->segment(1) == 'admin')
{
    // load admin menu
}
else
{
    // load main menu
}

The URI class is ALWAYS autoloaded so you don't have to load anything to make this work

I hope this solved your problem
