next step:
- view & edit is now integrated in the views - view has now buttons to edit, edit-series, copy, delete and delete-series - add: participants/resources can now be set via the url - conflict check is coded, but need testing and a conflict display

/**
|
||||
* Class to access AND manipulate all calendar data
|
||||
*
|
||||
* Note: All new code should only access this class or bocal and NOT bocalendar!!!
|
||||
*
|
||||
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
|
||||
* UI only operates in user-time, so there have to be no conversation at all !!!
|
||||
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
|
||||
* SO operates only in server-time (please note, this is not the case with the socalendar*-classes used atm.)
|
||||
*
|
||||
* As this BO class deals with dates/times of several types and timezone, each variable should have a postfix
|
||||
* appended, telling with type it is: _s = seconds, _su = secs in user-time, _ss = secs in server-time, _h = hours
|
||||
*
|
||||
* All new BO code (should be true for eGW in general) NEVER use any $_REQUEST ($_POST or $_GET) vars itself.
|
||||
* Nor does it store the state of any UI-elements (eg. cat-id selectbox). All this is the task of the UI class !!!
|
||||
*
|
||||
* All permanent debug messages of the calendar-code should done via the debug-message method of the class !!!
