Is there already ANY solution how to insert/edit/delete events in google Calendar using Zend Gdata Framework. Since November 17 it doesn't work.

Thanks

Answer 1

//How to use the class:

$gcal=new gcalendar('**your_mail_adress**');//TO CHANGE

It's not your mail adress here but your calendar id

Answer 2

First you have to follow this step: http://cornempire.net/2012/01/08/part-2-oauth2-and-configuring-your-application-with-google/

When it's done you can use my class : !! Curl has to be enable on your server.

class gcalendar{
    private $cal_id;
    //To get credentials follow this steps ==> http://cornempire.net/2012/01/08/part-2-oauth2-and-configuring-your-application-with-google/
    private $client_secret='to_change';//TO CHANGE
    private $refresh_token='to_change';//TO CHANGE
    private $client_id='to_change';//TO CHANGE
    public  $spindle='+01:00';
    private $token;

    public function __construct($cal_id){
        $this->token=$this->get_access_token();
        $this->cal_id=$cal_id;
    }

    //Retourne un token
    private function get_access_token(){
        $tokenURL = 'https://accounts.google.com/o/oauth2/token';
        $postData = array(
            'client_secret'=>$this->client_secret,
            'grant_type'=>'refresh_token',
            'refresh_token'=>$this->refresh_token,
            'client_id'=>$this->client_id
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $tokenURL);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        $tokenReturn = curl_exec($ch);
        $token = json_decode($tokenReturn);

        $accessToken = $token->access_token;
        return $accessToken;
    }

    //liste tous les events sur la période définit en param
    public function list_events($start_date,$end_date){
        return $this->execute('list_events',false,array('start_date'=>$start_date,'end_date'=>$end_date));
    }

    //Récupere l'event ayant l'id passer en param
    public function get_event($event_id){
        return $this->execute('get_event',false,array('event_id'=>$event_id));
    }

    //Ajoute un event !!Attention$_data doit respecter une certaine syntaxe voir plus bas fonction create_args!
    public function add_event($_data){
        $args=$this->create_args($_data);
        return($this->execute('add_event',$args));
    }

    //Modifie un rdv (heures, titre ou contenu).
    public function update_event($event_id,$_data){
        $ev=json_decode($this->get_event($event_id));
        $_data['sequence']=$ev->sequence+1;
        $args=$this->create_args($_data);
        return($this->execute('update_event',$args,array('event_id'=>$event_id)));
    }

    //Supprime un event
    public function delete_event($event_id){
        return $this->execute('delete_event',false,array('event_id'=>$event_id));
    }

    /*
    **  $_data=array( 
                !start_date =>  Date de début de l'event au format Y-m-d
                !start_time =>  Heure de début de l'event au format HH:ii
                !end_date   =>  Date de fin de l'event Y-m-d
                !end_time   =>  Heure de fin de l'event HH:ii
                summary     =>  Titre de l'event (title)
                description =>  Description de l'event
                sequence    =>  Sequence de l'event (C'est un numéro à incrémenter à chaque update de l'event). Obligatoire lors d'un update.
            )
        Les champs avec un ! sont obligatoires!

    */
    private function create_args($_data){
        $_args=array(   'start'     =>  array('dateTime'=>$_data['start_date']."T".$_data['start_time'].":00.000".$this->spindle),
                        'end'       =>  array('dateTime'=>$_data['end_date']."T".$_data['end_time'].":00.000".$this->spindle));
        unset($_data['start_date']);
        unset($_data['start_time']);
        unset($_data['end_date']);
        unset($_data['end_time']);
        foreach($_data as $key=>$value){
            $_args[$key]=$value;
        }
        return json_encode($_args);
    }

    //execute les requetes curl adaptée selon le type ($type_exe)
    private function execute($type_exe,$args=false,$opt=false){
        switch ($type_exe){
            case 'list_events':
                $request='https://www.googleapis.com/calendar/v3/calendars/'.urlencode($this->cal_id).'/events?timeMax='.urlencode($opt['end_date'].'T23:59:59.000'.$this->spindle).'&timeMin='.urlencode($opt['start_date'].'T00:00:01.000'.$this->spindle);
                $session = curl_init($request);
            break;
            case 'get_event':
                $request='https://www.googleapis.com/calendar/v3/calendars/'.urlencode($this->cal_id).'/events/'.$opt['event_id'];
                $session = curl_init($request);
            break;
            case 'add_event':
                $request='https://www.googleapis.com/calendar/v3/calendars/'.urlencode($this->cal_id).'/events';
                $session = curl_init($request);
                curl_setopt ($session, CURLOPT_POST, true);
            break;
            case 'update_event':
                $request =  'https://www.googleapis.com/calendar/v3/calendars/'.urlencode($this->cal_id).'/events/'.$opt['event_id'];
                $session = curl_init($request);
                curl_setopt($session, CURLOPT_CUSTOMREQUEST, "PUT");
            break;
            case 'delete_event':
                $request='https://www.googleapis.com/calendar/v3/calendars/'.urlencode($this->cal_id).'/events/'.$opt['event_id'];
                $session = curl_init($request);
                curl_setopt($session, CURLOPT_CUSTOMREQUEST, "DELETE");
            break;
        }
        if($args){
            curl_setopt ($session, CURLOPT_POSTFIELDS, $args); 
        }
        curl_setopt($session, CURLOPT_HEADER, false); 
        curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($session, CURLOPT_VERBOSE, true);
        curl_setopt($session, CURLINFO_HEADER_OUT, true);
        curl_setopt($session, CURLOPT_HTTPHEADER, array('Content-Type:  application/json','Authorization:  Bearer ' . $this->token,'X-JavaScript-User-Agent:  My_company'));
        $response = curl_exec($session);
        curl_close($session); 
        return $response;
    }
}

And this is how you can use it

//How to use the class:
$gcal=new gcalendar('**calendar_id**');//TO CHANGE
// Add an event 
$result=$gcal->add_event(array('start_date'=>'2014-11-20','start_time'=>'12:00','end_date'=>'2014-11-20','end_time'=>'14:00','summary'=>'My event','description'=>'The desc of my event'));

//List events between two dates
    // $result=$gcal->list_events('2014-11-01','2014-11-30');

//update an event with ID
    // $result=$gcal->update_event('ID_OF_EVENT',array('start_date'=>'2014-11-20','start_time'=>'12:00','end_date'=>'2014-11-20','end_time'=>'14:00','summary'=>'Rdv banane','description'=>'Ceci est une banane'));

//Delete an event with ID
// $result=$gcal->delete_event('ID_OF_EVENT');

//Display result
$res=json_decode($result);
print_r($res);

Hope it will help. If you have any question...
