在代码点火器中跳跃控制器

Question

I am wanting to have a form of dynamic routing.

Basically I want to catch the 404 (done through routes.php 404_override).

This is easy enough.

But then what I want to do is run through a series of checks.

e.g pay no attention to the fact the is_xxx functions are not coming from anywhere

$what = $this->uri->segment(1);
if(is_vanity_name($what)){
    //now I want to route this to the profile controller and call the display function like so 
    //display('vanity', $what);
}
elseif(is_region_name($what)){
    if(($deal = $this->uri->segment(2)) !== false){
        //now I want to route to the deals controller can call the display function like so
        //display($deal, $what);
    } 
    else {
        //now I want to route to the deals controller and call the daily function like so
        //daily($what);
    }
}
elseif(is_deal_name($what)){
    //now I want to route to the deals controller and call the display function like so
    //display($what);
}
else{
    $this->load->view('errors/404');
}

And thats a pretty basic example!

So my question is, How would I go about re-routing to the other controllers once the decision has been made?

Broadly speaking, its kind of messy doing this with CodeIgniter. Coming from java land the RequestDispatcher.forward() takes care of these sorts of things, but in PHP space its usually a redirect(): there typically isn't the server side infrastructure to (effectively) pass requests from one PHP file to another without the client-side round trip.

Looking through Google's eyes: http://codeigniter.com/forums/viewthread/55212/P15/ is a long discussion with a CI helper that claims to let you do this, http://codeigniter.com/wiki/Wick/ is a library that appears to actually do it.

Let me know if either of those work out: you might be better off refactoring those out, but that does get tedious after awhile so I can understand the desire to just pass the handling off to the other controller (why bother round-tripping if you don't have to).
