[pmwiki-users] ListPages ?

[The Editor]

I can't seem to get this little bit of code working right.  After hours...

The first conditional is triggered properly.  Before the question mark
line, I can return $g as the group I'm wanting to list.  But "hi"
never appears. It's as if it can't find any of the pages.  This is
supposed to do my threading function...

	$e = 1000;
	if (strpos("$vv[0]$vv[1]", "#") || strpos("$vv[0]$vv[1]", "=")) {
		$g = $vv[0];
//  return $g;
???           foreach(ListPages("/^$g\\.\\d/") as $n) {
return "hi";
			$n = substr($n,strlen($g)+1);
			$e = max($e,$n);
			}
		if ((PageExists("$vv[0].$e")) && (strpos("$vv[0]$vv[1]", "#"))) $e = $e + 1;
		}

If someone could help explain the ListPages function a bit I'd
appreciate it.  I'd like to also use it to verify more accurately
whether or not any pages exist in a given group (without having to
rely on existence of a recent changes page).
