There’s actuall a small problem with solving the “–” issue. You still need to define the prefix as blank otherwise it prints it as “undefined” on the page :P

As for the single vote per user and other features I have mentioned, Alex has contacted me about these. I’m going to start working on making these features configurable and once done will send it to Alex for review.

I think the look-up of the postID failed in canVote() before a refresh of the page, so that the query returned no result and hence allowed more votes.

BTW, I have left the IP check on, this is needed as I don’t even allow user reg on my blog (it’s a security risk).

I will post my code here:

bizpsyq.co...ss_php.txt

Note that I moved some things around for debugging purposes, so just do a search for

“function canVote(”

and read from there.

I really want to be able to tell it to only count the first click, but I’m too much of a noob to figure it out.

I agree this is a great script though, if I could only get it working properly!

In ck_karma.js line 61, replace the if else statement with
if(response[2] > 0){
var prefix = ‘+’;
}

and in ck_karma.php line 73 do something similar
if($karma > 0) {
$karma = ‘+’. $karma;
}

the values are actually stored as negative in the DB so the prefix isn’t needed. I have also changed ck_karma with the following features if anyone is interested:
- Removed the IP check and allowed each registered user to only vote once per comment.
- Only allow registered users to rate comments
- disable voting when the post has comments disabled

I need to make these configurable really, but there you go :) These are just some hacks I did to get this great script to work how I wanted :)

1) I’m using Wordpress Thread Comment (http://blog.2i2j.com/plugins/wordpress-thread-comment)
to create– yes– threaded comments, and I can’t figure out how to make CK show up within the threaded comments. It works great for the original comments, but doesn’t display in the responses. How can I get it to work in the threaded responses to a comment?

2) As a convenience for my impatient readers, I also have Inline Ajax Comments installed, so comments can be accessed at the bottom of each post. That works fine (I know: it’s not supported any more) but is there a way to get CK to work in those comments as well?

Works fine now.

function get_top_comment($postId) {
global $wpdb;
$sql = “SELECT comment_ID, comment_date, comment_author, comment_author_url, comment_content, SUM(ckTbl_rating) AS ratings_total
FROM wp_ckTbl_commentMain, wp_comments
WHERE ckTbl_comment_id = comment_ID
AND comment_post_ID = $postId
GROUP BY ckTbl_comment_id
ORDER BY ratings_total DESC, comment_date ASC;”; // the date is the tie-braker, earlier comment wins

$comments = $wpdb->get_results($sql);
$topcmt = $comments[0]; // take the top-most one, we have sorted for it to be the top comment
if (!$topcmt->comment_ID) $topcmt=0; // if it’s not set, return 0
return $topcmt;
}

in ckarma.php:

function get_top_comment($postId) {
global $ckarma;
$topcmt = $ckarma->get_top_comment($postId);
return $topcmt;
}

then use

$topcmt = get_top_comment(get_the_ID());

$topcmt->comment_author

and so forth in e.g. the while(have_posts()) loop in your index.php to do stuff with the top comment, or place elsewhere in your templates or custom widgets.

Watch this function in action on my blog:

businessmi...dhacks.com
(top comment excerpt with DoFollow link displayed if present for every post on the index page)

Best - Alex

if (get_comment_author_url() && ($karma > -5)) {
display comment_author() inside of comment_url() link …
} else {
display comment_author() only
}

I was wondering how the “bury” is actually implemented, since I couldn’t find anything about it in your plugin code.

As a quick hack, I added a function to ckarma.php:

function get_cmt_karma($id) {
global $ckarma;
$karma = $ckarma->getKarma($id);
return $karma;
}

that I then call in my comments (foreach) loop right at the top:

$karma = get_cmt_karma(get_comment_id());
if ($karma < -9) continue;

So we skip over “buried” comments with ratings of -10 or less; set your own threshold here.

Then you can also use this as a qualifier when writing the comment header info to turn off e.g. a DoFollow link for a spammy comment.

Anyway, hope someone finds this useful, I would still be interested if there was some sort of implementation of the “bury” that I overlooked.

I too am working on a way to get the top comment for a post, easiest would likely be to add a field ck_post_id to the table and save this on “insert”. Else it’s going to have to be a pretty messy (and slower) join of the wp_comments and wp_ckTbl_ tables.

Thanks for the great plugin.

Specifically, when the plugin installs, it creates these columns in the MYSQL database as containing type VARCHAR. I changed them to INT and BIGINT respectively. It’d probably be a good idea if the plugin author changed this bit of code. Otherwise the plugin works great, thanks Alex!
