In my previous blog post, I wrote about how to get the pagetitle of the current resource's parent. It occurred to me that a more generic snippet that would get *any* field from the parent might be useful. Instead of the parent's pagetitle, you might want its menuindex, longtitle, description, introtext (summary), or some other field.

This is a fairly minor modification of the previous snippet. The only real difference is that the name of the desired field is set as a snippet property and used as a variable in the snippet.

This tag goes where you want to display the parent's field:

[[!getParentField? &field=`pagetitle`]]

And here's the snippet:

/* getParentField snippet */

$parentObj = $modx->getObject('modResource', $modx->resource->get('parent'));
$field = $scriptProperties['field'];

if ($parentObj) {
    return $parentObj->get($field);
} else {
    return '';
}

See this page for a list of the available parent fields. You must use the exact field name (in all lowercase) for the field you want.

Here's the more compact version:

/* getParentField snippet */

$parentObj = $modx->getObject('modResource', $modx->resource->get('parent'));
return $parentObj? $parentObj->get($scriptProperties['field']) : '';
