Here is an example:

  $FmtPV['$YourVariable'] = 'YourFunction("$group.$name", $page["title"])';
  function YourFunction($pagename, $targetpagetitle) {
    global $Whatever;

    # do something with $pagename
    $uppercase = strtoupper($pagename);

    # or, instead of RetrieveAuthPage(), just use PageVar()
    $mytitle = PageVar($pagename, '$Title');
    $myvalue = PageVar($pagename, '$:MyTextVar');

    # return something
    return $Whatever . $myvalue;


The "$group.$name" part will be supplied automatically according to the  
target page, so {$Var} will refer to the current page, {OtherPage$Var} will  
refer to the other page ("$group.$name" will be passed as  

If you have the patience, you can read the definitions of the default page  
variables in pmwiki.php, lines 121-151 approximately.
