I'm trying to use Google calendar api and its php client library to make a php function that add an event with the variables i give it through parameters.
But it seems that the documentation is outdated, and i can't find a good tutorial to help me. Here is what I've done for the moment :
<?php
require_once 'google-api-php-client/autoload.php';
session_start();
//require_once 'google-api-php-client/src/Google/Client.php';
//require_once 'google-api-php-client/src/Google/Service/Calendar.php';
$client = new Google_Client();
$client->setApplicationName("test");
$client->setClientId("xxxx.apps.googleusercontent.com");
$client->setClientSecret("xxxx");
$client->setRedirectUri("http://localhost/");
$client->setDeveloperKey("xxxx");
$service = new Google_Service_Calendar($client);
$event = new Google_Service_Calendar_Event();
$event->setSummary('Appointment');
$event->setLocation('Somewhere');
$start = new Google_Service_Calendar_EventDateTime();
$start->setDateTime('2014-10-16T10:00:00.000-07:00');
$event->setStart($start);
$end = new Google_Service_Calendar_EventDateTime();
$end->setDateTime('2014-10-16T10:25:00.000-07:00');
$event->setEnd($end);
/*$attendee1 = new EventAttendee();
$attendee1->setEmail('attendeeEmail');
$attendees = array($attendee1,
// ...
);
$event->attendees = $attendees;*/
$createdEvent = $service->events->insert('primary', $event);
echo $createdEvent->getId();
?>
And my browser tells me :
Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/primary/events?key=xxxx: (401) Login Required' in C:\wamp\www\cnsi\google-api-php-client\src\Google\Http\REST.php on line 76
Could someone help me please ?
I recommend that you used libraries of Zend Framework for it.
checkout http://framework.zend.com/manual/1.12/en/zend.gdata.calendar.html
I'm trying to use a service account to create entries on a Google calendar. I'm really close on this, but the very last line won't work. I get a 500 Internal Service Error when I let this run. Otherwise, the program runs error free, for whatever that is worth.
The Calendar.php file contents can be found here. The insert() method that I am trying to call begins on line 1455 of that file.
<?php
function calendarize ($title, $desc, $ev_date, $cal_id) {
session_start();

$event = new Google_Service_Calendar_Event();
$event->setSummary($title);
$event->setDescription($desc);
$start = new Google_Service_Calendar_EventDateTime();
$start->setDate($ev_date);
$event->setStart($start);

$calendarService = new Google_Service_Calendar($client);

// if I leave this line, my code won't crash (but it won't do anything, either)
//echo "here"; die();
$events.insert($cal_id, $event, false);
}
?>
I figured this out. Since I don't see any complete examples of using service accounts with API v3, I'm just going to post my complete solution for reference. There are a few of things that you need to do in addition to implementing the code, however:
1) You need to go to the Google Developer's console and mark your account as a 'service account'. This will differentiate it from a web application. The important difference is that nobody will be prompted to log in to their account before the events are added since the account will belong to your application, not an end user. For more information see this article, starting on page 5.
2) You need to create a public/private key pair. From the developer's console, click on Credentials. Under you service account, click on 'Generate new P12 key'. You'll need to store this somewhere. That file location becomes the $key_file_location variable string in the code below.
3) Also from the developer's console, you need to enable the Calendar API. From your project, on the left margin you'll see APIs. Select that and find the Calendar API. Click it, accept the terms of service, and verify that it is now displayed under Enabled APIs with a status of On
4) In Google Calendar that you want to add events to, under settings, click Calendar Settings then on 'Share this Calendar' at the top. Under 'Share with specific people' in the 'Person' field, paste in the email address from the service account credentials. Change the permission settings to 'Make changes to events'. Don't forget to save the change.
Then, implement this code somewhere.
Comment if something is confusing or omitted. Good luck!

Some helpful resources:
Github example for service accounts
Google Developers Console for inserting events in API v3
Using OAuth 2.0 to Access Google APIs
Here is the Google API Client 2.0 way to do
Follow Alex's Answer Go Google Developer's console to create Service Account, but create credential in JSON
Follow Google API Client Upgrade Guide, install by composer and include in the way of
require_once 'vendor/autoload.php';
Follow Alex's Answer to go to Google Calendar to share the calendar with Service Account ID
xxxxx#yyyy.iam.gserviceaccount.com
Take Ref. to below coding and the most important one is the calendar id should be the email of calendar creator, but not primary
<?php
require_once __DIR__.'/vendor/autoload.php';
session_start();
$client = new Google_Client();
$application_creds = __DIR__.'/secret.json'; //the Service Account generated cred in JSON
$credentials_file = file_exists($application_creds) ? $application_creds : false;
define("APP_NAME","Google Calendar API PHP"); //whatever
$client->setAuthConfig($credentials_file);
$client->setApplicationName(APP_NAME);
$client->addScope(Google_Service_Calendar::CALENDAR);
$client->addScope(Google_Service_Calendar::CALENDAR_READONLY);
//Setting Complete
//Go Google Calendar to set "Share with ..." Created in Service Account (xxxxxxx#sustained-vine-198812.iam.gserviceaccount.com)
//Example of Use of API
$service = new Google_Service_Calendar($client);
$calendarId = 'xxxx#gmail.com'; //NOT primary!! , but the email of calendar creator that you want to view
$optParams = array(
'maxResults' => 10,
'orderBy' => 'startTime',
'singleEvents' => TRUE,
'timeMin' => date('c'),
);
$results = $service->events->listEvents($calendarId, $optParams);
if (count($results->getItems()) == 0) {
print "No upcoming events found.\n";
} else {
echo "Upcoming events:";
echo "<hr>";
echo "<table>";
foreach ($results->getItems() as $event) {
$start = $event->start->dateTime;
if (empty($start)) {
$start = $event->start->date;
}
echo "<tr>";
echo"<td>".$event->getSummary()."</td>";
echo"<td>".$start."</td>";
echo "</tr>";
}
echo "</table>";
}
I'm trying to do add an event. I use client libraries.
After passing oAuth I get
Fatal error: Call to a member function insert() on a non-object in zarzadzaj/kursy.php on line 17
My code is:
<?php
require_once '../zarzadzaj/src/Google_Client.php';
require_once '../zarzadzaj/src/contrib/Google_CalendarService.php';
$event = new Google_Event();
$event->setSummary('Appointment');
$event->setLocation('Somewhere');
$start = new Google_EventDateTime();
$start->setDateTime('2011-06-03T10:00:00.000-07:00');
$start->setTimeZone('America/Los_Angeles');
$event->setStart($start);
$end = new Google_EventDateTime();
$end->setDateTime('2011-06-03T10:25:00.000-07:00');
$end->setTimeZone('America/Los_Angeles');
$event->setEnd($end);
$anEvent = $service->events->insert('primary', $event);
echo $anEvent->getId();
?>
What am i doing wrong?
I found the Solution...
You need to declare '$service' as an instance of the google calendar service first before you call the insert() method..This worked for me...I hope this works for you too..
$service = new Google_CalendarService($client);
I am encountering a problem with my code when I am trying to retrieve events on the google calendar. Below is my code:
<?php
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_CalendarService.php';
session_start();
$client = new Google_Client();
$client->setApplicationName("Google Calendar PHP Starter Application");
// Visit https://code.google.com/apis/console?api=calendar to generate your
// client id, client secret, and to register your redirect uri.
$client->setClientId('client id');
$client->setClientSecret('client secret');
$client->setRedirectUri('redirect uri');
$client->setDeveloperKey('developer key');
$cal = new Google_CalendarService($client);
$events = $cal->events->listEvents('email address for google calendar');
echo $events;
?>
When I print out the events of my google calendar, all I get is an empty array. However I am sure that I have several events in my google calendar.
In fact, I event tried to add an event by using the code below:
$event = new Google_Event();
$event->setSummary('Appointment');
$event->setLocation('Somewhere');
$start = new Google_EventDateTime();
$start->setDateTime('2013-08-23T10:00:00.000-07:00');
$event->setStart($start);
$end = new Google_EventDateTime();
$end->setDateTime('2013-08-23T10:25:00.000-07:00');
$event->setEnd($end);
echo $events;
$createdEvent = $cal->events->insert('email address for google calendar', $event);
However, when I do this code I end up receiving an error that says:
Fatal error: Uncaught exception 'Google_ServiceException' with message 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/'email address for google calendar'/events?key='key'......................................lib/google-api-php-client/src/io/Google_REST.php on line 66
Can someone help me on this?
As it's an array you need to use print_r instead of echo. Try replacing:
echo $events;
with
print"<pre>".print_r($events, true)."</pre>";
I'm finally able to get an Access Token, now I'm very confused as how to add a Calendar using only Google's provided apiClient.
$apiClient = SiteController::getApiClient();
$service = new apiCalendarService($apiClient);
$calendar = new Calendar();
$calendar->description = "What";
$service->calendars->insert($calendar);
This produces:
Error calling POST https://www.googleapis.com/calendar/v3/calendars?key=mykey: (400) Required
Is there some documentation/examples on adding a Calendar? There are a ton of examples, it seems like, for simply adding an Event.
I'm a little closer now, I get
apiServiceException
Error calling POST
https://www.googleapis.com/calendar/v3/users/me/calendarList?key=mykey: (404) Not Found
Using the boilerplate code they gave on the documentation
$calendarListEntry = new CalendarListEntry();
$calendarListEntry->setId("calendarId");
$createdCalendarListEntry = $service->calendarList->insert($calendarListEntry);
echo $createdCalendarListEntry->getSummary();
Inserting a new calendarEntry in google calendar API v3 returns a 404
How do I change my request URL from
https://www.googleapis.com/calendar/v3/users/me/calendarList?key=mykey
to
https://www.googleapis.com/calendar/v3/calendars
This worked:
// Create new calendar
$apiClient = SiteController::getApiClient();
$service = new apiCalendarService($apiClient);
$calendar = new Calendar();
$calendar->setSummary(Home::model()->count() . '-' . $model->name);
$createdCalendar = $service->calendars->insert($calendar);
You can reference Google Calendar API v1 Developers' Guide.
