Comments on my first CI application (Calendar/event) - El Forum - 07-31-2007

Hi,

first I must give my respect to the guys behind this framework. I really love it so far.


Second: the topic issue. I've just puzzled together something that atleast looks like a event calendar.

It works, _but_ I want to get some feedback on the structure and inprovments for the logic, so I can go further in the learning process.


// THE CONTROLLER (kalender.php)

Code:
class Kalender extends Controller {

    // Constuctor

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

        $this->load->library('calendar');
        $this->load->model('kalender_model');
    }

    // index

    function index()
    {
        redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location');
    }

    function dato()
    {    
        // Grab some vars

        $cal_year = $this->uri->segment(3);
        $cal_month = $this->uri->segment(4);
        $cal_day = $this->uri->segment(5);


        // Check if is numeric

        if(!empty($cal_year) && ctype_digit($cal_year) == FALSE)
        {
            redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location');
        }

        if(!empty($cal_month) && ctype_digit($cal_month) == FALSE)
        {
            redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location');
        }

        if(!empty($cal_day) && ctype_digit($cal_day) == FALSE)
        {
            redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location');
        }

        // Redirect if empty vars

        if(!$cal_year || !$cal_month)
        {    
            redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location');
        }


        // Setup calendar

        $prefs = array (
            'start_day'    => 'monday',
            'month_type'   => 'long',
            'day_type'     => 'abr',
            'show_next_prev'  => TRUE,
            'next_prev_url'   => base_url() . 'kalender/dato/'
            );

        $this->calendar->initialize($prefs);


        // Say hello to the models

        $data['event_data'] = $this->kalender_model->get_events($cal_year, $cal_month);

        // If day isset, get day info

        if($cal_day)
        {
            $data['event_day_data'] = $this->kalender_model->get_day($cal_year, $cal_month, $cal_day);    
        }


        // Tell it to the viewer

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

    }

}


// THE MODEL (kalender_model.php)

Code:
class Kalender_model extends Model {

    // Constuctor

    function __construct() {

        parent::Model();

    }

    function get_events($year, $month) {

        $first_day = mdate('%Y-%m-%d', mktime(0,0,0,$month,1,$year));
        $last_day = mdate('%Y-%m-%d', mktime(0,0,0,$month,days_in_month($month, $year),$year));

        $this->db->where('event_date >', $first_day);
        $this->db->where('event_date <', $last_day);
        $query = $this->db->get('kalender');

        if ($query->num_rows() > 0)
        {
            foreach($query->result() as $k => $row)
            {
                $key = mdate('%j', mysql_to_unix($row->event_date));

                $data_array[$key] = base_url() . 'kalender/dato/' . $year . '/' . $month . '/' . str_pad($key, 2, '0', STR_PAD_LEFT);
            }

            return $data_array;
        }
    }

    function get_day($year, $month, $day) {

        $first_day = mdate('%Y-%m-%d', mktime(0,0,0,$month,1,$year));
        $last_day = mdate('%Y-%m-%d', mktime(0,0,0,$month,days_in_month($month, $year),$year));
        $current_day = mdate('%Y-%m-%d', mktime(0,0,0,$month,$day,$year));

        $this->db->where('event_date =', $current_day);
        $query = $this->db->get('kalender');

        if ($query->num_rows() > 0)
        {
            foreach($query->result() as $k => $row)
            {
                $key = mdate('%d', mysql_to_unix($row->event_date));

                $data_array[$k]['dato'] = base_url() . 'kalender/dato/' . $year . '/' . $month . '/' . $key;
                $data_array[$k]['body'] = $row->body;
                $data_array[$k]['title'] = $row->title;
            }

            return $data_array;
        }
    }
}



// THE VIEW (kalender_view.php)

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

&lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="no" lang="no"&gt;
&lt;head&gt;
    &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
    &lt;meta name="robots" content="index,follow" /&gt;
    &lt;meta name="description" content="" /&gt;
    &lt;meta name="keywords" content="" /&gt;

    &lt;title&gt;Title&lt;/title&gt;
    
&lt;/head&gt;

&lt;body&gt;

    <div id="container">

    &lt;?php
    
    echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4), $event_data);
    
    if($this->uri->segment(5)){
        
        foreach($event_day_data as $value) {
            echo '<h2>' . $value['title'] . '</h2>';
            echo '<p>' . $value['body'] . '</p>';
        }    
    }
    
    ?&gt;

    </div>

&lt;/body&gt;
&lt;/html&gt;


Well, that's all folks, and thanks for all the fish.

Instead of repeating this:
Code:
redirect('kalender/dato/'. date('Y') . '/' . date('m') . '/','location')
Would it be easier to make the redirect destination a variable? You could do something like this:
Code:
var $redirect_destination = 'kalender/dato/'. date('Y') . '/' . date('m') . '/';
Then:
Code:
redirect($redirect_destination,'location')

I am new to CI, and I wanna implement this app on my site.

Y have some questions for this application.

How can I setup the database for this calendar?
How can I do a page for add events?
Can I see the links rendered in a calendar?, or this app only show me the events when are called from URI.

It could be great a wiki entry for this app.

Thanks in advance
