This is part of pnRender, your only problem was not knowing how the variable was contained (in this case part of an associative array). To find out which variables are available to any template simply insert into the template and load the page, you will get a popup window of all the available arrays neatly listed for you.
pnRender is a postnuke specific
API for
Smarty, to learn how to use
Smarty (and thereby pnRender) see the
Smarty Documentation. Just substitute thier curly bracket tags {} with
PN's custome tags and your golden.
Once you've got the basic logic constructs down have a look at the directory modules/pnRender/plugins for
PN specific plugins that any template can use. You can also use the plugins in modules/Xanthia/plugins for Xanthia themes. And if you have a look at the SeaBreeze theme you'll see that you can have custom theme plugins as well.
I may also be starting up a pnRenders Anon to help those more seriously addicted to pnRender... have fun.
