Peter, thx so much for your reply. I was suspecting that much. That’s why I
tried to write some markup to actually register a real PV (with <{$var}
priority), but I couldn’t get that to work beyond the scope of a single page.
As far as I can tell, the problem breaks down this single question:
Why can a php script referenced in the skin’s .tmpl file access PTVs and PVs
set by (:var: :) and (:var :) but not when those are within a pagelist? Is
there a way to tell the script to run ‘>pagelist’ (after all pagelists have
been processed)?
I will also look into triggering the script as a php markup script
(<!--markup:(:somescript:)--> instead of <!--file:somescript.php-->). hopefully
this workaround will solve the order issues by having PmWiki figure them out.
