How to add events dynamically?

jyuzakumo 2011-10-13 08:24:41 UTC #1

Hello gentlemen,

I have been trying to understand the codes of the application for the last couple of days and I just can’t understand how the API works and therefore can’t have the job done.
Mission is to add events automatically using external data (from another server providing dates of calendar events) when users are logged. The function I am trying to write must grab the username and search into the databases of the other server for the events in order to add new events into the calendar of the user. I am stuck at the very beggining.

Can someone please help me on this ? I am kind of comfortable with PHP but man this EGW apps is just too much for me to handle alone.

Thank you for time and have a nice day !

Most easy is do do CalDAV a PUT request with an iCal file. That way you
can eg. update the events to.

Hey Ralf,

Thanks for your quick reply. Unfortunately I don’t understand how to do what you advice.
Can you be a little more specific ? Danke schon !

Ralf_Becker_Stylite 2011-10-13 09:25:16 UTC #4

Google for CalDAV rfc and search there for PUT

PUT is a HTTP request method like GET or POST.

URL would be:
http(s)://domain.com/egroupware/groupdav.php/calendar/.ics

Hey,

Thanks for the input, it was quite entertaining. But I don’t think it is exactly what I need.
I am gonna try to be a little more clear.

I have got egroupware on my server called agenda. And I have got this other application on server B where members put their leave of absence. Kind of like the calendar application but it is our main system application with everything (absence, work time etc…). I am trying to put those leave of absence into the agenda calendar of users.
Now thanks to you I created my own egroupware application where I am able to extract the user’s data I need (datetime period of absence) from the server B. All I need now is to create the eventinto the calendar using those data.

What is the function to create the events ? I was able to locate the ui.form function edit which is (apparently) the function that insert data into the Database but I don’t know how to proceed from here.

Morning people,

Was looking for some answers here and there and I found out that someone managed to succeed on adding events by injecting stuff directly into the database. But I am quite concerned about those kind of barbarism since I do like to do things flawlessly without overpassing the API.
I tried to watch for the POST variables sent during the validation of an event but I just got lost like a kid.

ngegw 2011-10-14 14:06:28 UTC #7

Fast and dirty answer:
Look in calendar/inc/class.calendar_bo.inc.php, and
calendar/inc/class.calendar_boupdate.inc.php.
All the API stuff in egw is in *_bo files. See some of the other
command line scripts for how your script can get a session.

However, this is a one way trip for your data, and there are already a
few different methods to get external data into egw. In the event of
an adjustment or cancellation of leave, you have no way to update the
events. I would strongly recommend using CalDAV with an ics file as
Ralf recommends, or Import/Export.

Hey Nathan,

Thanks for your answer. Do you have some tuto or some link about the second solution ?
I googled the terms but ended up more confused… I know I am a pain to deal with but how about I pray for your success in this life (and the other) in exchange !

Hello guys,

Hope you are doing well !
I have got a question. When I point Firefox to the link :
server/egroupware/groupdav.php/calendar
I get a blank screen (which is usually leading to a php coding issue). Problem is my log files doesn’t seem to detect any error.

What could be the problem here ?

You sure you get a HTTP status of 500? Eg. Firefox or Chrome can show
http status of requests.

You should have a trailing slash:

http(s)://domain.com/egroupware/groupdav.php/calendar/

Actually I am getting a 404.

I double checked and my file is obviously present in my root among the index.php, logout.php files.

Are you using Apache with mod_php or something else (CGI, FCGI)?

What happens if you try it with just
http://agenda/egroupware/groupdav.php (nothing after .php)?

Hey Ralf,

Heard my man Sarkozy went to visit your girl Merkel. You guys should be careful with that dude

Well if my session is active I still get the blank screen. But if I log out of the session and point the address in Firefox, it asks me a login and a psw. And still get the blank after logging in though. Kind of strange, I tried with the original code of groupdav.php and nothing changes.
