How to create next prev by week in Codeigniter calendar

[eluser]Unknown[/eluser]
Hi Team,

I would like to make a new customize for event calendar with CodeIgniter next previous url week by week in each month.

I have already extends and customize the calendar to display as week view with this following code:

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/**

*
* This class enables the creation of calendars

* @package  CodeIgniter

class MY_Calendar extends CI_Calendar {

/**
  * Generate one week the calendar
  *
  * @access public
  * @param integer the year
  * @param integer the month
  * @param array the data to be shown in the calendar cells
  * @return string
  */

Does anyone have any suggestion and good deal with this issue?
I would need more guideline and description because I am just a junior developer with CI!

thanks,
