无法获得递归API Google Calendar PHP

Question

I am trying to get the recurrence of an event with the Google Calendar API in PHP, and it doesn't show me the recurrence.

The following code is the code I'm using:

$params = array(
                'orderBy' => 'startTime',
                'singleEvents' => true,
                'timeMin' => date('c'),
        );
        $listarEventos = $service->events->listEvents($calendar_id, $params);
        foreach ($listarEventos->getItems() as $i){
            echo "<pre>";
            echo $i->recurrence;
            print_r($i);
            echo "</pre>";
            echo "<br>";
        }

And I am obtaining this type of objects:

Google_Service_Calendar_Event Object
(
    [collection_key:protected] => recurrence
    [internal_gapi_mappings:protected] => Array
        (
        )

                )

                )

            [end] => Array
                (
                    [dateTime] => 2015-06-19T09:03:00+02:00
                    [timeZone] => Europe/Madrid
                )

            [reminders] => Array
                (
                    [useDefault] => 1
                )

        )

    [processed:protected] => Array
        (
        )

)

I have to say that I store the recurrence with the following code:

$event->setRecurrence(array('RRULE:FREQ='.$FREQ.';INTERVAL='.$INTERVAL));

And I have proved that the event is recurrent, so I don´t know why I can't get the recurrence.

Thanks a lot!

Answer 1

You won't get recurrence if you're using 'singleEvents' => true .

Documentation ( https://developers.google.com/google-apps/calendar/v3/reference/events/list ) says:

singleEvents boolean Whether to expand recurring events into instances and only return single one-off events and instances of recurring events, but not the underlying recurring events themselves. Optional. The default is False.

Answer 2

I have solved the question. You won't get the recurrence if you doesn't get the event with something like this:

$event = $service->events->get('primary', "recurringEventId");

Once you have $event, you can use:

$preevent->recurrence[0]

Thanks to Xeron for the answer.
