Would someone please tell me how to get TV values from the results of getIterator? The following does not seem to work:

<?php

$output = '';
$resource = $modx->resource;
$id = $modx->resource->get('id');

$children = $modx->getIterator('modResource',array(
	'published' => 1,
	'template' => 16,
	'parent' => $id
));

$output = '<ol>';

foreach ($children as $n => $child) {
	$output .= '<li>';
	$output .= 'Title: ' $child->get('pagetitle');
	$output .= 'ThumbnailImageTV: ' $child->TemplateVarResources['ThumbnailImageTV']->get('value');
	$output .= '</li>';
}

$output .= '</ol>';

return $output;

I am just trying to retrieve the value of a TV called 'ThumbnailImageTV'

@Bruno17, Thank you!!! That worked!

For reference and for others the final code is below. This snippet gets published child resources of the current resource that use a certain template. This would be useful for creating a landing page or thumbnail grid of resources.

<?php
$output = '';
$id = $modx->resource->get('id');

$children = $modx->getIterator('modResource',array(
	'published' => 1,
	'template' => 16,
	'parent' => $id
));

$output = '<ol>';

foreach ($children as $child) {
	$output .= '<li>';
	$output .= 'Title: ' . $child->get('pagetitle');
	$output .= 'ThumbnailImageTV: ' . $child->getTVValue('ThumbnailImageTV');
	$output .= '</li>';
}

$output .= '</ol>';

return $output;
