Question by: highlander

Is there a way to know how many parents any given document has or, how far down the tree structure a document is located?

noOfParents snippet:

<?php

$id = isset($id) ? $id : $modx->resource->get('id');
$pids = $modx->getParentIds($id, 100, array('context' => 'de'));
return count($pids);

Sidenote: You may remove the paramter part (array(...) if you are content with your current context.
