Trying to get attendees set in google calendar API / PHP - php

Question

I´m trying to create an event and that part works, but it will not for some reason send out the invitations / attendees in the calendar system with google API using PHP. It does create the event but that also it. So I hope someone can help me figuring out what I´m doing wrong.
myfile.php
// Event details
parameters = { title: $("#event-title").val(),
event_time: {
start_time: $("#event-type").val() == 'FIXED-TIME' ? $("#event-start-time").val().replace(' ', 'T') + ':00' : null,
end_time: $("#event-type").val() == 'FIXED-TIME' ? $("#event-end-time").val().replace(' ', 'T') + ':00' : null,
event_date: $("#event-type").val() == 'ALL-DAY' ? $("#event-date").val() : null
},
'attendees': [
{'email': 'test#dds-slagelse.dk'},
],
all_day: $("#event-type").val() == 'ALL-DAY' ? 1 : 0,
};
$("#create-event").attr('disabled', 'disabled');
$.ajax({
type: 'POST',
url: 'ajax.php',
data: { event_details: parameters },
dataType: 'json',
success: function(response) {
$("#create-event").removeAttr('disabled');
alert('Event created with ID : ' + response.event_id);
},
error: function(response) {
$("#create-event").removeAttr('disabled');
alert(response.responseJSON.message);
}
});
ajax.php file
session_start();
header('Content-type: application/json');
require_once('google-calendar-api.php');
error_log($_SESSION['access_token']);
try {
// Get event details
$event = $_POST['event_details'];
error_log(__LINE__);
$capi = new GoogleCalendarApi();
error_log(__LINE__);
// Get user calendar timezone
$user_timezone = $capi->GetUserCalendarTimezone($_SESSION['access_token']);
error_log(__LINE__);
// Create event on primary calendar
error_log($event['attendees0']);
$event_id = $capi->CreateCalendarEvent('primary', $event['title'], $event['all_day'], $event['event_time'], $event['attendees'], $user_timezone, $_SESSION['access_token']);
error_log(__LINE__);
echo json_encode([ 'event_id' => $event_id ]);
}
catch(Exception $e) {
error_log($e->getMessage());
header('Bad Request', true, 400);
echo json_encode(array( 'error' => 1, 'message' => $e->getMessage() ));
}

$http_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
if($http_code != 200)
throw new Exception($http_code);
return $data['id'];
}
}
I hope this make sense as I have tried so many attempts that I have lost track of it.
The Form Data that is send (after what i can figure out from google chrome is the following:
event_details[title]: Privat
event_details[event_time][start_time]: 2018-08-11T13:00:00
event_details[event_time][end_time]: 2018-08-11T15:30:00
event_details[event_time][event_date]:
event_details[attendees][0][email]: test#dds-slagelse.dk
event_details[all_day]: 0

Answer 1

ADyson, thanks for your help / hint. It was the missing curl that was the solution.
$curlPost['attendees'] = $event_attendees;
I hope it wont be to much of a bother, but it seems that it does not send out the invites for the events as hoped, even thought it does add the "guests" to the event.
The starting point for this solution is found here: http://usefulangle.com/post/29/google-calendar-api-create-event-php and if someone can please helt me to get * "sendNotifications"=>true * inserted or set correctly I would be very thankful. (would like to see how that parameter / function is set).
Best Regards
Jess

Answer 2

This help to me:
$curlPost['attendees'] = [['email'=>$event_data['attendees']]];
$curlPost['sendUpdates'] = array("sendUpdates"=>"all");
$curlPost['reminders'] = array('useDefault' => true, 'overrides' => array('method' => 'email','minutes' => 20));
