[pmwiki-users] New Hierarchical Groups Recipe...

[The Editor]

Very helpful Pm!  Appreciate very much the long email...  It did not
seem to work exactly as you explained, but I did come up with a
workaround.  Below are a few comments...  I cut out several sections
of your explanation, if the below seems choppy...

This was what I was looking for.  Makes sense now.

I actually had my own function I wanted to use because I have a couple
extra really useful features thrown in.  Namely, that you can define a
base starting point for links subgroups, to make it easy for users to
create links far down the chain.  Nice!  Also that you can make the
slashes optional for some seem to prefer the clear group.page
distinction.

I seem to have gotten around this, because while my home system failed
the EnaglePathInfo test, the custom ResolvePageName function I'm using
seems to get around the problem.  Which is nice because I never could
get cleanurls to work.  But now my links are all working with just
this:

$FmtPV['$PageUrl'] = 'PUE("$ScriptUrl?n=" . hgUrl("$pn"))';

I was hoping to use url rewriting to eliminate even need for index.php
and ?n= so I'm not worrying about that at this time.

I should be able to upload the revised recipe later today.  When I do,
Pm, please take a look over it to see if it looks ok.  Pretty
exciting...  Thanks again so much for your patient explanations.
Extremely help as always!

Cheers,
Dan
