iCal downloads for events

[swordfischer]

I've created some mock-up code:

This is for next event

<?php

include('/var/www/steamlug.org/steameventparser.php');

$parser = new SteamEventParser();
$eventarr = $parser->genData("steamlug");

$ical = "BEGIN:VCALENDAR
VERSION:2.0
PRODID:http://steamlug.org
BEGIN:VEVENT
UID:" . md5(uniqid(mt_rand(), true)) . "@steamlug.org
DTSTAMP:" . gmdate('Ymd').'T'. gmdate('His') . "Z
DTSTART:" . date('Ymd', strtotime($eventarr["events"][0]["date"])) . 'T' . date('His', strtotime($eventarr["events"][0]["time"])) . "Z
DTEND:" . date('Ymd', strtotime($eventarr["events"][0]["date"])) . 'T' . date('His', strtotime($eventarr["events"][0]["time"])+7200) . "Z
SUMMARY:". $eventarr["events"][0]["title"] . "
END:VEVENT
END:VCALENDAR";

header('Content-type: text/calendar; charset=utf-8');
header("Content-Disposition: inline; filename=" . str_replace(' ', '_', $eventarr["events"][0]["title"]) . ".ics" );
echo $ical;
exit;

?>

This is for custom event and MUST be sanitized

<?php

include('/var/www/steamlug.org/steameventparser.php');
$parser = new SteamEventParser();
$eventarr = $parser->genData("steamlug");

$dtstart = $_GET["dtstart"];
$dttime  = $_GET["dttime"];
$summary = $_GET["title"];

$ical = "BEGIN:VCALENDAR
VERSION:2.0
PRODID:http://steamlug.org
BEGIN:VEVENT
UID:" . md5(uniqid(mt_rand(), true)) . "@steamlug.org
DTSTAMP:" . gmdate('Ymd').'T'. gmdate('His') . "Z
DTSTART:" . date('Ymd', strtotime($dtstart)) . 'T' . date('His', strtotime($dttime)) . "Z
DTEND:" . date('Ymd', strtotime($dtstart)) . 'T' . date('His', strtotime($dttime)+7200) . "Z
SUMMARY:". $summary . "
END:VEVENT
END:VCALENDAR";

header('Content-type: text/calendar; charset=utf-8');
header("Content-Disposition: inline; filename=" . str_replace(' ', '_', $summary) . ".ics" );
echo $ical;
exit;
?>

I've been using this for some time now, and it works as I intended, and solves my issues with ical downloads for each event dev.steamlug swordfischer_icalfeed/feed/calendar.php

I've been subscribed to it as well, and it seems to have been working fine (although I can't recall if there have been new events added since).

Should we get some more testing done before pushing it live, or are we good with it as is?

It is live now. https://steamlug.org/feed/calendar.php
