Filter comments by node type

Well, the point was to make the comments available to the autocomplete more limited. For example, I was going to use this for a special node type "moderator note" and have my moderators create nodes to record misbehavior in forums. So the comment reference autocomplete would allow them to select the comment(s) involved.
Here's the problem: they only need to see comments for, say, the last thirty days in that autocomplete... and it actually makes selection of comments more difficult if comments three years old also appear in the autocomplete... and it seems like a list that long would be slower as well.
We average about 200 comments a day, I'm told (at our non-Drupal site).

It's not urgent. For now, I'm planning on implementing the "moderator notes" feature w/ordinary text field, and moderators can paste in URL's like they're used to. But a comment ref. field that is useful in our situation would be slick.

Not knowing much about the guts of the module (OK, knowing zero), maybe it would be easier to add an admin option to "limit comments to last 30 days" or something and skip Views. Works just as well for me.

Super. Many thanks.

Checking it out

I'm not seeing the new settings... where should they be?

Edit: had wrong version of the file. See the settings now. Testing.

This is working fine for me. So far, I only have a couple dozen comments (not live site yet), but works well on these.

Have another suggestion, but I'll put it in a new feature req.

Have another suggestion related to this: how hard would it be to display the CID in the autocomplete along w/the info that displays there now (time, etc.)?

Tested. No parsing errors. Seems to work fine, and looks good. Thanks.

One small issue: when I include the commentreference field in a View (as a linked title), it also displays the time as "x days x hours ago" ... which is cluttering up the View a bit since I don't really need that info in there. Not sure why that happens. It would be OK, too if I knew where to change the format to something more compact instead of "ago" time.

Well, I have to learn to write overrides sooner or later. Might as well be now...
What I understand is that I want to do an implementation of hook theme_commentreference_formatter_default (is that the right lingo?) in my theme's template.php file.

... and "theme_" has to change to "superdupercustomthemeImademyself_" Right so far?

In the .module, I see this...

function theme_commentreference_formatter_default($element) {
$output = '';
if (!empty($element['#item']['cid']) && is_numeric($element['#item']['cid']) && ($title = _commentreference_titles($element['#item']['cid']))) {
$referenced_comment = _comment_load($element['#item']['cid']);
$output = l($referenced_comment->subject, 'node/'. $referenced_comment->nid, array('fragment' => 'comment-'. $referenced_comment->cid)) .' - '. t('@time ago', array('@time' => format_interval(time() - $referenced_comment->timestamp)));
}
return $output;
}

So I want to put all that in my template.php file, replace "theme_" with whatever, then change things to get the look I want.

So, any hints on what I should change? I don't really know what any of it means.... wait a sec. Maybe I do... enough to do some guessing. Will play with this and see what results I get. Meanwhile, if you have a sec. and can straighten me out where I'm wrong, much appreciated.

Got it. Just did the above and then removed .' - '. t('@time ago', array('@time' => format_interval(time() - $referenced_comment->timestamp)))
