为代码点火器日历中的每个日期生成唯一的 URL

我有一个显示月历的日历控制器和模型。用户可以单击上一个和下一个超链接来循环访问月份。我还能够每天生成一个唯一的URL，因此，例如，当有人想要单击2012年4月10日时，他们将获得类似.../2012/04/10的URL。我的问题是，当我转到另一个月份时，所有日期 URL 仍然将四月显示为月份。

控制器

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);
}

型

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'] = '
