[pmwiki-users] using PTVs from pagelists in skin scripts (or how to register a new PV)

[a.sonderhoff at gassi-tv.de]

Hi Peter,

thanks a lot for your advice. I had a look at Hans’ powertools recipe, but then opted for the quick and dirty solution to use (:setSomeVar {=$FullName}:) in the pagelist template (together with the markup to translate the directive into a global variable) to work around the PTV limitations.

>             $t = preg_replace("/\\{\\$:{$m[2]}\\}/", '', $m[3]);
>             $pc["=p_{$m[2]}"] = Qualify($pagename, $t);
>           }

Thanks for pointing out this section. Now I do understand, why it’s not possible to use PTVs in a pagelist.

Take care
