Create html link:

Create user controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class User extends CI_Controller
{

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

        // Load form helper library
        $this->load->helper('form');

        // Load form validation library
        $this->load->library('form_validation');

        // Load session library
        $this->load->library('session');

        $this->load->model('Data_model');
    }

    public function changePassword()
    {
        $web = array();
        $web['title'] = 'Change password';
        $web['content'] = 'web/password';

        $this->form_validation->set_rules('old_password', 'Old password', 'required|callback_check_password');
        $this->form_validation->set_rules('new_password', 'New password', 'required');
        $this->form_validation->set_rules('confirm_password', 'Confirm password', 'required|matches[new_password]');

        if ($this->form_validation->run() == FALSE) {
            $this->load->view('web_template',$web);
        } else {

            $id = $this->user_id;

            $data = array(
                'user_password' => $this->input->post('new_password'),
            );

            $this->Common_model->Data_model('user_login', $data, 'id', $id);
            $this->session->set_flashdata('msg', 'Password changed Successfully');

            redirect('user/changePassword');
        }

    }

    function check_password($password) {        
        if($this->user_id)
            $id = $this->user_id;
        else
            $id = '';

        $result = $this->Data_model->check_user_password($id, $password);
        if($result > 0)
            $response = true;
        else {
            $this->form_validation->set_message('check_password', 'Old password is wrong');
            $response = false;
        }

        return $response;
    }
}

Create Data_model in model add this function:
