GetResources Snippet calls

I’d like to dynamically retrieve the content of a MODx Revo document into another one and I understand that the GetResources snippet is designed to do just that like the GetField does on Evo.

<?php
$value = '';
if ($object = $modx->getObject($class, $modx->fromJSON($where))) {
    $value = $object->get($field);
}
return $value;
?>

[[getValue? &class=`modResource` &field=`content` &where=`{"id":12}`]]

[[getValue? &class=`modUser` &field=`username` &where=`{"id":[[*editedby]]}`]]

getResources is for summarizing Resources, similar to Ditto.

If all you want to do is get a field from an object in the MODx core, try a simple snippet like this, which I call getValue:

<?php
$value = '';
if ($object = $modx->getObject($class, $modx->fromJSON($where))) {
    $value = $object->get($field);
}
return $value;
?>

You could then call this with a variety of arguments to get a piece of MODx data. To get the content of the Resource with id 12:

[[getValue? &class=`modResource` &field=`content` &where=`{"id":12}`]]

To get the username of the User with based on the current Resource’s editedby value:

[[getValue? &class=`modUser` &field=`username` &where=`{"id":[[*editedby]]}`]]

A quick question. I’ll be using this sipped to load form data like country names in a select box.
Is there any downside to doing that you think?
