Insert event in google calender

Question

I am trying to insert an event in my calendar using calendar id.

I just copied a code snippet from here

and downloaded SDK from here

Here is my code

<?php 
// Refer to the PHP quickstart on how to setup the environment:
// https://developers.google.com/google-apps/calendar/quickstart/php
// Change the scope to Google_Service_Calendar::CALENDAR and delete any stored
// credentials.

include('google-api-php-client-2.0.3/vendor/autoload.php');
include('google-api-php-client-2.0.3/src/Google/Client.php');
include('google-api-php-client-2.0.3/src/Google/Service/Resource.php');


include('google-api-php-client-2.0.3/google-api-php-client-2.0.3/vendor/google/apiclient-services/src/Google/Service/Calendar.php');
include('google-api-php-client-2.0.3/google-api-php-client-2.0.3/src/Google/Service.php');

$event = new Google_Service_Calendar_Event(array(
  'summary' => 'Google I/O 2015',
  'location' => '800 Howard St., San Francisco, CA 94103',
  'description' => 'A chance to hear more about Google\'s developer products.',
  'start' => array(
    'dateTime' => '2015-05-28T09:00:00-07:00',
    'timeZone' => 'America/Los_Angeles',
  ),
  'end' => array(
    'dateTime' => '2015-05-28T17:00:00-07:00',
    'timeZone' => 'America/Los_Angeles',
  ),
  'recurrence' => array(
    'RRULE:FREQ=DAILY;COUNT=2'
  ),
  'attendees' => array(
    array('email' => '[email protected]'),
    array('email' => '[email protected]'),
  ),
  'reminders' => array(
    'useDefault' => FALSE,
    'overrides' => array(
      array('method' => 'email', 'minutes' => 24 * 60),
      array('method' => 'popup', 'minutes' => 10),
    ),
  ),
));

$calendarId = '[email protected]';

$client = new Google_Client();

    $client->setApplicationName("schedular app");
    $client->setClientId('xxxxx.apps.googleusercontent.com');
    $client->setClientSecret('xxxxxxxxxxxxx');


$service = new Google_Service_Calendar_Events_Resource($client,$event,'','');
$events = $service->insert($calendarId, $event);
printf('Event created: %s\n', $event->htmlLink);



?>

but I am getting error like

Fatal error: Cannot declare class Google_Service, because the name is already in use in D:\xampp\htdocs\gmt\google-api-php-client-2.0.3\src\Google\Service.php on line 18

How to solve this. or what i am doing wrong. please help.

I guess the root of your problem is that you are using too many includes. Use only include('google-api-php-client-2.0.3/vendor/autoload.php'); and delete the rest of them. I think that the way your code is structured should be enough to create the event, but the way I prefer doing it is this way:

<?php

session_start();

//INCLUDE PHP CLIENT LIBRARY
require_once "google-api-php-client-2.0.3/vendor/autoload.php";

$client = new Google_Client();
$client->setAuthConfig("client_creds.json");
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/index.php');
$client->addScope("https://www.googleapis.com/auth/calendar");

if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {

    $client->setAccessToken($_SESSION['access_token']);

    $cal = new Google_Service_Calendar($client);

    $event = new Google_Service_Calendar_Event(array(
      'summary' => 'Event One',
      'location' => 'Some Location',
      'description' => 'Google API Test Event',
      'start' => array(
        'dateTime' => '2016-11-14T10:00:00-07:00'   
      ),
      'end' => array(
        'dateTime' => '2016-11-14T10:25:00-07:00'
      ),  
      'reminders' => array(
        'useDefault' => FALSE,
        'overrides' => array(
          array('method' => 'email', 'minutes' => 24 * 60),
          array('method' => 'popup', 'minutes' => 10),
        ),
      ),
    ));

    $calendarId = 'primary';
    $event = $cal->events->insert($calendarId, $event);
    printf('Event created: %s\n', $event->htmlLink);

} else {

    if (!isset($_GET['code'])) {    

          $auth_url = $client->createAuthUrl();
          header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));

    } else {  

      $client->authenticate($_GET['code']);
      $_SESSION['access_token'] = $client->getAccessToken();

      $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/index.php';
      header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));

    }

}

?>

Please note that for the calendar Id value I am using 'primary' because it will be the primary calendar of the authenticated user. Please refer to the documentation here for more details. I hope this helps!
