Authenticating to Google Calendar API via Wordpress

[Christopher Mueller]

Hi guys, I'm having a tough time trying to get my WordPress site to authenticate into Google Calendar. The following code authenticates and can get/list/add events to my google calendar perfectly as a stand-alone php file on my localhost, however when I copy the code into my Wordpress files (I put it in at the top of header.php, though perhaps this is a bad idea?), I get the infamous php result Fatal error: Exception thrown without a stack frame in Unknown on line 0.

Has anyone interfaced with this before and knows what to do, or knows how to at least get around the Fatal error? Thanks in advance.

<?php

require_once 'path/to/Google_Client.php';

require_once 'path/to/Google_CalendarService.php';

define('SERVICE_ACCOUNT_NAME', 'XX...@developer.gserviceaccount.com');

define('KEY_FILE', '/path/to/keyfile/XXXXX-privatekey.p12');

$client = new Google_Client();

$client->setApplicationName("Name");

$client->setUseObjects(true);

if (isset($_SESSION['token'])) {

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

}

$key = file_get_contents(KEY_FILE);

$scopes = array('https://www.googleapis.com/auth/calendar');

$client->setAssertionCredentials(new Google_AssertionCredentials( SERVICE_ACCOUNT_NAME, $scopes, $key));

if (isset($_SESSION['token'])) {

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

}

$cal = new Google_CalendarService($client);

$fetchedEvent = (array)$cal->events->get('calendarID', 'eventID');

?>

Build your functionality as a custom plugin. Or try to create the features inside of functions.php and use built-in WordPress variables & functions to locate the files & include them, e.g. get_template_directory( ). Also due to how WordPress loads (sometimes more than once), you may need to surround each function/class with if( ! function_defined( 'function_name' )) { // function definition }  HTH -
