I had been given some PHP for a snippet on the forums a while back to assist me in submenus on the sidebar of pages with children resources. However, it no longer works in Revo 2.3. Can someone assist me in modifying it so it is 2.3 compatible?

Snippet:

<?php
$document = $modx->getObject('modResource', $id);
 
if($document){
    return $document->hasChildren()? '1' : '0';
}
 
return '';

Use:

[[hasChildren:is=`1`:then=`getResources Call`]]

It looks like it expects a property of &id with the ID of the parent.

If you want the snippet to use the current resource's ID by default try this version

<?php
$id = $modx->getOption('id', $scriptProperties, $modx->resource->get('id'));
$document = $modx->getObject('modResource', $id);  
if($document){
    return $document->hasChildren()? '1' : '0';
}
return '';

That extra line says "get the option named 'id' - from the snippet's properties - by default use the current resource ID".
