[pmwiki-users] discussion backlink

[noskule]

hi list

I try to make a backlink from a discussionpage. If discusstionpages are 
stored in a "discussion" group the macklink look like this.

Discussion.Group-Name -> Group.Name

$FmtPV['$BaseName'] = 'str_replace("-", ".", $name)';

the above example is form 
http://www.pmwiki.org/wiki/Cookbook/CommentPageLink

but how it works if I want to replace

Group.Name-Discussion -> Group.Name
