添加到网站的gCal按钮

Question

我正在寻找一种方法，使按钮出现在我的网站上，以便用户可以自动添加事件到他们的谷歌日历，类似于什么是由http://www.addthisevent.com/做的(目前我正在使用)。

到目前为止，我已经在网上查看过了，但是我只能通过将它添加到我的日历中并从中生成代码来找到一种手动的方法。不过，我想用PHP自动完成它。

我不想继续下去的理由是让自己控制网站上加载的所有资源。

编辑:我正在寻找一个链接，用户可以点击和一个新的选项卡将打开添加日历约会打开和预先填充(就像add事件所做的那样)。解决方案应该是PHP，并且接受google日历所需的所有变量。

下面的一些代码可能会有所帮助：

谷歌日历：

<?php
function generate_calendar_button($name, $description, DateTime $start, DateTime $end, $location, $mysite_url, $mysite_name) {
   $url = 'http://www.google.com/calendar/event?action=TEMPLATE';
   $parts = array();
   $parts['text'] = urlencode($name);
   $parts['details'] = urlencode($description);
   $parts['dates'] = urlencode($start->format("Ymd\THis\Z")) . "/" . urlencode($end->format("Ymd\THis\Z"));
   $parts['location'] = urlencode($location);
   $parts['sprop'] = urlencode($mysite_url);
   $full_link = $url;
   foreach ($parts as $key => $value) {
      $full_link .= "&" . $key . "=" . $value;
   }
   $full_link .= "&sprop=name:" . urlencode($mysite_name);
   return '<a href="' . $full_link . '" target="_blank"><img src="http://www.google.com/calendar/images/ext/gc_button1.gif" border=0></a>';
}

print generate_calendar_button(
    "Boulevard Summer Show",
    "Starting Friday 15th June, the Boulevard Summer Show 2012 features new sets and musical numbers led by the legendary Betty Legs Diamond, performing alongside established favourites and some rather fetching new faces, all held together by the incomparable Miss Rory.",
    new DateTime("2012-07-15 8:00 GMT"),
    new DateTime("2012-07-15 10:00 GMT"),
    "123 Example Lane, Exampleville",
    "http://www.northernpink.co.uk/",
    "Northern Pink"
);

?>

苹果iCal：

<?php // Add a custom button after the event export options that display after the event content


$ical = "BEGIN:VCALENDAR

END:VCALENDAR";

//set correct content-type-header
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: inline; filename=calendar.ics');
echo $ical;
exit;
