you have ommited your code

the following works:

Code:

<?php
class Events extends Controller {

    function __construct()
    {
        parent::__construct();
    }

    function index()
    {
        // don't need anything here for this example
    }
    
    function viewdetails()
    {
        echo $this->uri->segment(3);
        $id = $this->uri->segment(3);
    }

    function viewdetails2($id=NULL)
    {
         //this also works      
        echo $id;
    }
}

URL - index.php/events/viewdetails/2

outputs 2.

note the "echo" - unless you are assigning the value to a variable, calling just $this->uri->segment(3) will not output anything on its own.

or...

Code:

class Events extends Controller {
    
    function viewdetails($id)
    {
        echo $id;
    }

}
