So here we go:
http://www.modxcms.de/index.php?id=7
Lots of hacking was neccessary to include it. Some problems were:
- unb uses "id" for identification of pages->modx also. So I changed it to "unb_id" (not quick but dirty).
- the inclusion is called in a function (so does every inclusion via snippet). So I had to declare all global vars from unb again in the included file (forum.php).
- there are some @function occurrences in unb, their disabled error messages are catched and displayed by modx. So I had to intercept them in the code of unb.
Some problems and todos still remain:
-Short URLs (SEF) need to be investigated, not quite sure if they ever will work.
-Synchronization of user tables, so that logging in modx->logging in in unb and vice versa
-the "veriword" function (image displayed with characters on it for spam protection) doesn´t work, so I disabled it for now.
But for today it´s enough
