Google Calendar Plugin

dwd0tcom · August 16, 2021, 8:40pm

Hey everybody,

I’m running into an issue which I can’t fix and can’t even understand: I’m using the Google Calendar Plugin for Kirby and it breaks when it tries to get the DateTime of an event. Pretty strange since I can access every other key in the JSON except this one.

The author of the plugin seems to be gone so my hope is this forum.

The JSON looks like this:

and the part where the dateTime key seem to be parsed looks like this:

$events[$i] += ["datestart" =>  new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])->format(option('benediktengel.google-calendar-plugin.formatDate')))];

Pretty normal to me but it won’t access the array. I tried everything, even creating a new JSON Parse to just access this array but it still won’t work.

If you have any hint for me, I would be super happy!

It’s a syntax error. There need to be parenthesis around the new object, before calling the format() method:

$events[$i] += ["datestart" =>  (new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])))->format(option('benediktengel.google-calendar-plugin.formatDate'))];

I don’t know. I tried to access another key written in camelcase and got the same error.
Your snippet now throws this:

ParseError thrown with message “syntax error, unexpected ‘->’ (T_OBJECT_OPERATOR)”

I corrected my code, I’d anyway write this whole snippet differently:

$events[] = [
  "title"       => $event['summary'],
  "datestart"   => (new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])))->format(option('benediktengel.google-calendar-plugin.formatDate')),
  "timestart"   => (new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])))->format(option('benediktengel.google-calendar-plugin.formatTime')),
  "dateEnd"     => (new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['end']['dateTime'])))->format(option('benediktengel.google-calendar-plugin.formatDate')),
  "timeEnd"     => (new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['end']['dateTime'])))->format(option('benediktengel.google-calendar-plugin.formatTime')),
  "url"         => $event['htmlLink'] ?? '',
  "description" => $event['description'] ?? '',
  "location"    => $event['location'] ?? '',
];

Oh wow, you’re so quick! Thanks.
Looks way better, but something is still wrong. I don’t know if it can access the dateTime from JSON now. Because:

TypeError thrown with message "DateTime::__construct() expects parameter 1 to be string, object given"

texnixe · August 16, 2021, 9:43pm

What is in line 50 now?

dwd0tcom · August 16, 2021, 9:45pm

Line 50 is the first line with DateTime:

texnixe · August 16, 2021, 9:49pm

Hm, ok, then that didn’t work, back to the drawing board. Could you quickly provide a bit of sample data to copy paste? A json string…

dwd0tcom · August 16, 2021, 9:54pm

Sure! This should work:

{
  "kind": "calendar#events",
  "etag": "isThisDataSensitive?",
  "summary": "Zusammenfassung",
  "description": "Beschreibung",
  "updated": "2021-07-22T01:13:17.507Z",
  "timeZone": "Europe/Berlin",
  "accessRole": "reader",
  "defaultReminders": [],
  "nextPageToken": "tokenMacTokface",
  "items": [
    {
      "kind": "calendar#event",
      "etag": "xx",
      "id": "xxx",
      "status": "confirmed",
      "htmlLink": "https://google.com",
      "created": "2014-04-05T09:35:14.000Z",
      "updated": "2014-04-05T10:12:00.455Z",
      "summary": "Zusammenfassung",
      "location": "München, Deutschland",
      "creator": {
        "email": "elon@musk.com",
        "displayName": "Elon Musk"
      },
      "organizer": {
        "email": "Jeffrey@bezos.com",
        "displayName": "Jeff",
        "self": true
      },
      "start": {
        "dateTime": "2014-04-07T18:00:00+02:00"
      },
      "end": {
        "dateTime": "2014-04-07T19:00:00+02:00"
      },
      "iCalUID": "anotherID",
      "sequence": 0,
      "eventType": "default"
    }
  ]
}

texnixe · August 16, 2021, 10:04pm

I’m sorry, the original code was correct after all, too late

$events[] = [
  "title"       => $event['summary'],
  "datestart"   => new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])->format(option('benediktengel.google-calendar-plugin.formatDate'))),
  "timestart"   => new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['start']['dateTime'])->format(option('benediktengel.google-calendar-plugin.formatTime'))),
  "dateEnd"     => new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['end']['dateTime'])->format(option('benediktengel.google-calendar-plugin.formatDate'))),
  "timeEnd"     => new DateTime(DateTime::createFromFormat("Y-m-d?H:i:sP", $event['end']['dateTime'])->format(option('benediktengel.google-calendar-plugin.formatTime'))),
  "url"         => $event['htmlLink'],
  "description" => $event['description'] ?? '',
  "location"    => $event['location'] ?? '',
];

There seems to be another issue.

Did you get an error message or just no result?

dwd0tcom · August 16, 2021, 10:06pm

haha, no problem. I’m back at: Undefined index: dateTime
This also happens, when I’m trying to get the displayName for example

Oh I forgot: This happens at line 50

texnixe · August 16, 2021, 10:12pm

Does really every item in your json have a dateTime key?

texnixe · August 16, 2021, 10:13pm

Where is that called in the code?

Or to ask the question the other way round: Which keys do work?

dwd0tcom · August 16, 2021, 10:21pm

Somehow all keys work except those written in camelCase
So if I try to get the email in creator it works. But if I try to get displayName it breaks.
This is just an example, I never used it inside my code.

texnixe · August 16, 2021, 10:21pm

And could you insert a dump($event) after line 42?

But the camelCase keys are definitely there, so that’s weird.

dwd0tcom · August 16, 2021, 10:27pm

Here is the dump of the first array:

Array
(
    [kind] => calendar#event
    [etag] => "2xxx"
    [id] => xxx
    [status] => confirmed
    [htmlLink] => https://google.com
    [created] => 2014-04-05T09:35:14.000Z
    [updated] => 2014-04-05T10:12:00.455Z
    [summary] => xx
    [location] => xx
    [creator] => Array
        (
            [email] => email@mail.com
            [displayName] => email
        )

    [organizer] => Array
        (
            [email] => xxx
            [displayName] => Verein
            [self] => 1
        )

    [start] => Array
        (
            [dateTime] => 2014-04-07T18:00:00+02:00
        )

    [end] => Array
        (
            [dateTime] => 2014-04-07T19:00:00+02:00
        )

    [iCalUID] => xxx
    [sequence] => 0
    [eventType] => default
)

texnixe · August 16, 2021, 10:29pm

But I call it a day now before I write more nonsense…

It doesn’t make sense.

dwd0tcom · August 16, 2021, 10:29pm

Oh, if I limit the results to 30, it seems to work. It’s not displaying anything since all the events are in the past and the plugin only displays upcoming stuff but maybe there is something empty.

dwd0tcom · August 16, 2021, 10:30pm

Me too! Time for bed Thanks so much for your help! Good night!

dwd0tcom · August 16, 2021, 10:39pm

Alright, I think I got it:

If you decide to create an event on Google Calendar which is without a time, so just the date, the key is date and if you edit the event and decide to let it start at 6AM, it converts the date to dateTime
