Question

I have a calendar controller and model that displays a monthly calendar. A user can click on the previous and next hyperlinks to iterate through the months. I have also been able to generate a unique URL for each day, so when someone wants to click on April 10, 2012 for example they will get a URL something like …/2012/04/10. My problem is that when I go to another month, all the date URLs still show April as the month.

Controller

function display($year = null, $month = null) {

    $this->load->model('CalendarModel');

    if ($day = $this->input->post('day')) 
    {
        $this->CalendarModel->add_calendar_data("$year-$month-$day", $this->input->post('data'));
    }

    $data['Calendar'] = $this->CalendarModel->generate($year, $month);

    $this->load->view('Calendar', $data);

}

Model

class CalendarModel extends CI_Model 
{

    var $conf;

    function CalendarModel() 
    {
        $date = (!isset($_GET['month']) && !isset($_GET['year'])) ? time() : strtotime($_GET['month'] . '/1/' . $_GET['year']); 

        $day = date('d', $date); 
        $month = date('m', $date); 
        $year = date('Y', $date);

        $this->conf = array(
            'start_day' => 'sunday',
            'show_next_prev' => true,
            'next_prev_url' => '/CodeIgniter/index.php/Calendar/display'
        );

        $this->conf['template'] = '

            {table_close}</table>{/table_close}
        ';

    }

    function generate ($year, $month) 
    {

        $this->load->library('calendar', $this->conf);

        //$cal_data = $this->get_calendar_data($year, $month);

        return $this->calendar->generate($year, $month);

    }

}

Does this work?

  function CalendarModel($year = null, $month = null, $day = null)
  {       
         //$date = (!isset($_GET['month']) && !isset($_GET['year'])) ? time() : strtotime($_GET['month'] . '/1/' . $_GET['year']);
         //$day = date('d', $date);
         //$month = date('m', $date);
         // $year = date('Y', $date);  
         if ((is_null($year) || (is_null($month))
             {
                      // Do something if needed?
             }

          $this->conf = array( .... {continue rest of controller here as above}
