To be able to go deeper than 2 levels, instead of dirname() and basename(), you may
use explode("/", $midgard->uri)
Example:
<?
$path = explode("/", $midgard->uri);
for($i = $up = 0; $i < count($path); $i++) {
if(!$path[$i]) continue; // eliminate the first slash and double-slashes
$topic = mgd_get_topic_by_name($up, $path[$i]);
$up = $topic->id;
}
var_dump($topic);
?>
Hope that helps.
