Manage google calendar events.

• Read Events
• Update Event
• Delete Event
• Create Event

• The first step is to obtain credentials to access Google's API. I'm going to assume you already have a Google account and are logged in. Select a project in the Google API console clicking "Select a project."

• Click on ENABLE APIS AND SERVICES

• Search for calendar

• Chose GOOGLE calendar API

• Enable Api

• Go back to dashboard and Click on Credentials

• Click On Create Crendentials and chose Service Account

• Fill up details

• Finish the setup by clicking on done

• Click on newly Create Service Account Note the email for nex step. You have to use this email to manage calendar

• Click on keys

• Click on Add new key

• Chose Json and Download the key

• Go to Google calendar and Create a new calendar or chose a calendar.

• Scroll down to Share with specific people

• Click on add people and Add the Service account email ID which you copied or get it from the JSON File

• Finally Note Down calendar ID

• Install Google App Client via composer: composer require google/apiclient:^2.11
• Download this library by clicking here
• Extract the library to your project folder.
• Open Application/config/gcalendar.php file
• Add calendar ID and Json File Location (which you downloaded when you were generating Service account in the first step) . (I recomend you to put the JSON file in calendarData Folder)

$config['calendarId'] = "CALENDAR_ID"; $config['calendar_json_path'] = "SERVICE_ACCOUNT_JSON_FILE";//eg calendarData/calendarAPI.json

First Call The Library in Controller

$this->load->library("googlecalendar");

• Load Events

$this->googlecalendar->getAll();

• Load Specific Event

$this->googlecalendar->find("event_id");

• Query Event

$this->googlecalendar->where("key1","value1")->where("key2","value2")->get();

• Update Event

$this->googlecalendar->find("event_id"); $event->setSummary('Appointment at Somewhere'); $event->setLocation('Bangladesh'); $this->googlecalendar->update($event);

• Delete Event

$this->googlecalendar->delete("event_id");

• Create Event

$data = 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' => 'lpage@example.com'), array('email' => 'sbrin@example.com'), ), 'reminders' => array( 'useDefault' => FALSE, 'overrides' => array( array('method' => 'email', 'minutes' => 24 * 60), array('method' => 'popup', 'minutes' => 10), ), ), ); $this->googlecalendar->insert($data);

• You can also set some option parameters:

$this->googlecalendar->singleEvents(true)->showDeleted(false)->showHiddenInvitations(false) ->orderBy("startTime")->timeMin(mktime($hour, $minute, $second, $month, $day, $year)) ->timeMax(mktime($hour, $minute, $second, $month, $day, $year)) ->updatedMin(mktime($hour, $minute, $second, $month, $day, $year)) ->maxResults(10) ->getAll();

Some tips:

This command will bring all the gogle services in your vendor folder and creates a lot of unnecessary files. composer require google/apiclient:^2.11

So if you only need some specific services and don't need files for other services like addmob,drive,youtube you can put this in composer and run composer update

"require": { "php": ">=5.3.7", "google/apiclient": "2.11"	}, "scripts": { "post-update-cmd": "Google\\Task\\Composer::cleanup"	}, "extra": { "google/apiclient-services": [ "Calendar"	]	},

and run composer update

This will remove unnecessary service's files
