[eluser]metaltapimenye[/eluser]
this kind of stuff i work out with my last apps.
(read URI Class; Model)
url:http://www.mylandingsite.com/index.php/primary_class/restaurants/&lt;?php $this->uri->rsegment(2);?&gt; <--- this $this->uri->rsegment(n) stuff could be a variable to directing the methods behind.

in controller:

Code:

class primary_class extends Controller{
  function Gift(){
    parent :: controller();
  }
  function restaurants(){
    $page=$this->uri->rsegment(2);
    
    $this->load->view($page)
  }
}
