I need to sort the events by categorie. For example I have the following events for a day (weekly view, but also needed for the monthly and daily view):

C01 Systemkopie:: Wartung
Fred Flintstone :: Abwesenheit
Q01: Release 4:: Meilenstein
Q02: Kopie :: Wartung
Donald Duck :: Abwesenheit
08:00 - 17:00 Daisy Duck :: Dispatcher Backup
08:00 - 17:00 Barney :: Dispatcher
08:00 - 18:30 Supportzeit :: Anwesenheit

Now I need to sort the events by Categorie, for example the result should be:

Donald Duck :: Abwesenheit
Fred Flintstone :: Abwesenheit
Q01 Release 4:: Meilenstein
C01 Systemkopie:: Wartung
Q02: Kopie :: Wartung
08:00 - 18:30 Supportzeit :: Anwesenheit
08:00 - 17:00 Barney :: Dispatcher
08:00 - 17:00 Daisy Duck :: Dispatcher Backup

So the first sort criteria is all day event (or not), second I need category (Abwesenheit, Meilenstein, Wartung) and finally the title of the event. I found the old forum article (<!-- l --><a class="postlink-local" href="http://www.jevents.net/forum/viewtopic.php?f=6&;t=101#p282]viewtopic.php?f=6&t=101#p282[/url]<!-- l --> but I am not an php specialist so I need help.

I am using jevents 1.5.1 together with joomla 1.5.11, php version 5.2.5.
