        $this->form_validation->set_rules("email", 'Email', "trim|required|valid_email");
        if ($id)

            $this->load->view($this->module . '/manage', $data);

        else {
            $this->users_model->username = $this->input->post('username');
            $this->users_model->email = $this->input->post('email');

            $this->users_model->firstname = $this->input->post('firstname');
            $this->users_model->lastname = $this->input->post('lastname');
            $this->users_model->sex = $this->input->post('sex');

            if (strlen($this->input->post('password')) > 0)
                $this->{$this->model}->password = md5($this->input->post('password'));

            $this->{$this->model}->save();
            redirect('member/' . $this->module);
        }

        }else{
            exit('Hacking Attempt: Get out of the system ..!');
        }

    }

Users_model.php

<?php

class Users_model extends CI_model
{
    public $_table = 'users';
    public $_primary_keys = array('user_id');


}

Answer 1

First One you Must pass The user_id in session

Then Need domain/member/users/manage/1

You redirect to ur profile ...

If Users controller having function manage

class Users extends CI_Controller
{
  public function manage($userid)
  {
   #checking the with session value
   if(($this->session->userdata('user_id')!=$userid)):
      #if not satisfied means redirect another page
      redirect("Another page");
   endif;
  }
}
