Hi Paul et al.,
below please find a section that can be added to
plugins/calendar/calendar.php
to have a search field and the needed search algorithm for the web ui.
As mentioned, I moved my new code to a function to be added to above php.
This is for better overview.
The relevant function,
search_engine()
should be called last. So we have this order:
displayPageHeader($color, 'None');
calendar_header();
readcalendardata();
startcalendar();
drawmonthview();
endcalendar();
search_engine();
Since this mailing list's majordomo does not forward emails with
attachments, I add the function here as plain text.
Hope I could help!
Best regards,
Markus
