Need a query like getMany but with Order By

Right now I’m fetching related objects with getMany, but I need them ordered by a certain column. Is there an example somewhere on how to do this? It looks like I can use a criteria object to do it, but I’m stuck and can’t figure it out. So if someone can show me how to do it, or let me know if there is a better/easier way to do this then that would be awesome.

Thanks,

James

$criteria = $modx->newQuery('modResource');
$criteria->where(array(
   'parent' => $modx->resource->get('id'),
));
$criteria->sortby('pagetitle','ASC');
$children = $modx->resource->getMany('Children',$criteria);

To get the children of a document, sorted by Title:

$criteria = $modx->newQuery('modResource');
$criteria->where(array(
   'parent' => $modx->resource->get('id'),
));
$criteria->sortby('pagetitle','ASC');
$children = $modx->resource->getMany('Children',$criteria);

// Create a query for comments
$criteria = $wp->newQuery('Comments');
$criteria->where(array(
        'comment_post_ID' => $post->get('ID'),
));
// Here is where to set the sort order
$criteria->sortby('comment_ID','ASC');

// $post is a single post object, analogous to a single MODx resource object
// Here we tell xpdo to get all comments of this post, using our custom criteria
$comments = $post->getMany('Comments',$criteria);
