Calendaring class

[eluser]Drinian[/eluser]
Hi,

I've been trying to use the Calendaring class. The documentation seems to have an error in it regarding "Showing Next/Previous Month Links". It has you passing the prefs in the generate method, and I think it should be when you load the class.

However, even accounting for that, I can't get the next/previous links to work. They form properly but when you click on them I get a 404 page. Any advice? Thanks in advance.

Here's the code:

class Cal extends Controller {

function index() {

$prefs = array ('start_day' => 'saturday',
'month_type' => 'long',
'day_type' => 'short',
'show_next_prev' => TRUE,
'next_prev_url' => 'http://www.mydomain.com/index.php/cal/'
);


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

echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));

}

}

I believe that you need to hard code 'index' as the function name in your next_prev_url pref.

[eluser]Drinian[/eluser]
Yes, that is it. Thanks.

Yeah, I thought I remembered something weird like that. The calendar class is full of quirks like that which make it not the most (ahem) robust class for substantial development.

I can not even get the links to show up given the code in the API. Does anyone know how to fix this problem?

Check if you initialized the class in your controller:

Code:

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

If you want to set preferences they must be passed during the load, not during the 'generate' function (like the docs say in one place):

Code:

$prefs = array (
               'start_day'    => 'saturday',
               'month_type'   => 'long',
               'day_type'     => 'short'
             );

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

Then to see the calendar you echo the generate function:

Code:

echo $this->calendar->generate();

To show the next/prev links you set the prefs for that:

Code:

$prefs = array (
               'show_next_prev'  => TRUE,
               'next_prev_url'   => 'http://www.your-site.com/index.php/calendar/show/'
             );
$this->load->library('calendar', $prefs);
echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));

The above code has 'show' as the function in the controller. My problem was that I thought if I used 'index' I wouldn't have to explicitly list that in the next_prev_url but you do have to put it.

Hope that helps.

I am very sorry to say Calendar class of CI is not good enough. Not well configurable. Let me share some informations with you. According to CI user guide i found that the following code will able to display next/prev button

Code:

$prefs = array (
               'show_next_prev'  => TRUE,
               'next_prev_url'   => 'http://www.your-site.com/index.php/calendar/show/'
             );
$this->load->library('calendar', $prefs);
echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));

But i am surprised and waste a lot of my times with my believe. Finally i got that this code is not configurable. If anyone like to configure then he/she have to Edit the main Calendar class inside CI_Root/system/libraries. Isn't it looks funny? I need to configure inside a built in class!!
Still i am facing another problem. This time next/previous link add an extra segment. What is it !!!!

hmm my calendar function works fine,I dont have to edit the calendar library. the $this->uri->segment code is made so you can choose what month and years to display in your calendar.
