Answer 1

, if I'm not mistaken, then so. But this is in templates and chunks.
If we are talking about snippets, then I recommend reading a series of articles about xPDO , where this process is quite accessible and described in detail. One of the articles contains the following code:

$res = $modx->getObject('modResource', 16);
$tv = $res->getTVValue(4);
return $tv;
