The registered users on my website can create nodes from a content type called 'Stuff'. I'd now like to display the author's User Points he/she had when he/she created the node. That means: the value shouldn't be updated when the author's User Points change in the future.
How can I do that? Can I do a similar thing for comments?
Can this be done with a code/dynamic/preprocess field, provided by the Display Suite module?
@arpitr's tip for using the Computed Field module seems a pretty good idea, but as I replied to his answer, I don't know anything about PHP. I tried the following code, but it doesn't work.
global $user;
$entity_field[0]['value'] = "userpoints_get_current_points($user->uid)";
