im trying to go from mysite.com/signin/1 to mysite.com/course/enroll/1
but after validation_run() the segments just goes away.

PHP Code:
public function signin(course_id=null) {
  if(!$this->form_validation->run()){
    // wrong input
  }
  else{
    if(!empty($course_id)) {
       redirect(base_url('course/enroll/'.$course_id));
    }
    else {
       redirect(base_url('student'));
    }
  }
} 

i kept on being redirected to mysite.com/student even tho course_id is not empty.

right now, i just used session to get around this problem but i know that is not an efficient solution.

Have you done anything with routes? Based on the limited code shown you should not need to, but that's the only thing that comes to mind - assuming you have actually directed the browser mysite.com/signin/1 and not accidentally used mysite.com/signin/.

i have

my routes for these are

Code:
// normal signin

$route['signin'] = 'login/signin';

// if the student is not currently log in and wants to enroll to a course

// $1 is the course_id

$route['signin/(:num)'] = 'login/signin/$1';

normal signing-in works fine, but when i have to pass the course_id segment it disappears and redirects me to mysite.com/student

My Controller (Login.php)

PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login extends CI_Controller {

    public function signin($course_id=null)
    {
        $this->load->library('form_validation');
        $this->form_validation->set_rules('username','Username','trim|required');
        $this->form_validation->set_rules('password','Password','trim|required');
        if (!$this->form_validation->run()) {
            // validaiton failed
            $this->load->view('view_signin');
        }
        else {
            // validation success
            if (!empty($course_id)) {
                // redirect to enroll to course route
                echo "go enroll this course, where course_tbl.course_id = '$course_id'";
            }
            else
            {
                // redirect to normal site
                echo "normal login, redirect to student/index";
            }
        }
    }
}
