Question

I am using the following code to parse XML data from a Google Calendar feed:

    require_once('coreylib/coreylib.php');

    $calendar = variable_get('calendar_id_setting');

    $now = date('Y/m/d', strtotime('now'));
    $next_week = date('Y/m/d', strtotime('+7 days'));
    $api = new clApi('http://www.google.com/calendar/feeds/' . $calendar .'/public/full?singleevents=true&min-start=' . $now . '&max-start=' .$next_week);

    if ($feed = $api->parse()) {

        foreach($feed->get('entry') as $entry) {

                  error_log($title . ' ' . strtotime($entry->get('when@startTime')));

The problem is in the error log my first result is a unique event with correct title and time, but the following 25 results all have the same title and have a start time in 2026(?!).

All but one of the events are recurring events. I thought setting ‘singleevents=true’ on the URL would solve this problem but apparently not! What is the correct fix here?

Answer 1

Compare your URL with the one in the Calendar API v2 documentation. You’re providing parameters min-start and max-start, in a format of 'Y/m/d'. The documentation shows an example with parameters of

start-min=2006-03-16T00:00:00&start-max=2006-03-24T23:59:59

Note the use of start-min and start-max, and a format of yyyy-MM-dd'T'HH:mm:ss. Given the parameter reference I suspect you could get away with just yyyy-MM-dd, but you should follow that format rather than using slashes and single-digit versions.

Of course that doesn’t quite explain the results you’re getting in 2026, but using the right parameters would be a good starting point.

Additionally, you may wish to consider using the v3 API and possibly the PHP (beta) client library.

(Note: although I work for Google and used to use the client API myself, this answer is provided purely in a personal capacity.)
