processwire-calendar

Proof-of-concept alpha of a calendar for ProcessWire

The Calendar module creates a template for events as well as the four fields that the it expects in event pages.

event start date/time
event end date/time
event RRULE recurrence specification
event EXDATE recurrence exceptions

Recurring events are handled using the fruux/sabre-vobject library.

RFC 5545 RRULE and EXDATE are supported to the extent supported in the sabre-vobject library.

The ProcessCalendarAdmin module creates an admin page that uses fullcalendar present a more user friendly interface for managing events.

usage

Install the Calendar module
Create parent page to hold events
Configure the Calendar module to the right event "container"
Set up templates

Then

Install ProcessCalendarAdmin for calendar admin gui.

example 1 - get events and

When events are returned, a recurring event may generate many occurrences, so the results from Calender::expandEvents are array(start, end, page)

// get module
$calendar = wire('modules')->getModule('Calendar');
// get upcoming events - 6 months ahead
$start = new DateTime();
$until = new DateTime();
$until->add(new DateInterval('P6M'));
$events = $calendar->expandEvents($start, $until);
// render event
echo '<table>';
foreach($events as $event) {
    echo '<tr>';
    printf('<td>%s</td>', $event->start->format('Y-m-d H:i'));
    printf('<td>%s</td>', $event->end->format('Y-m-d H:i'));
    printf('<td>%s</td>', $event->event->title);
    echo '</tr>';
}
echo '</table>';

example 2 - ajax event loader

simply do this in your template.

calendar-event.php:

// ajax event request !
if ($config->ajax) {
    // build array to json encode
    $data = array(
        'id'    => $page->id,
        'title' => $page->get('title'),
        'body'  => $page->get('body'),
        'start' => $start->format(DateTime::ISO8601),
        'end'   => $end->format(DateTime::ISO8601),
        'recurs' => $page->calendar_event_rrule != '',
        'linkurl'  => $page->page->url
    );
    // encode and output
    header('Content-type: application/json');
    echo json_encode($data);
    return;
}
// handle normal event display or something

important note

Please note that the template and fields created when installing will not be removed when the module is uninstalled.
