- - Wluke, buddy - what happened to the karma hack? (https://vborg.vbsupport.ru/showthread.php?t=21668)

What happened to the karma hack, really? The community is just dying for one (lots of people want it). How is the development going? What is happening? Will you release it at all? Will it be included in 2.1? That would be great - preferably called "user rating", since most people are not familiar with the term "karma"...

I don't mind waiting, but I DO mind wondering - I'm a curious individual, you see. Oh, pretty, pretty pleeease give us an update on how it's going!

Business needs have dictated that I not pursue the Karma hack for my own purposes.

Instead we are developing a new system that will be used as a form of electronic currency in our forum for our members. As such it is not a user rating related feature anymore. Now SitePoint members will earn points (SitePoints, if you will) for contributing to the community. As time goes on they will be able to turn these points in for added member bonuses and discounts on products.

As such, I won't be persuing a simple "Karma" hack anymore. However here is the code that was used for the previous version of the hack. I converted this to PHP after looking at the PERL version written for UBB.

PHP Code:


		
			
<?php



require("global.php");

  $permissions=getpermissions($bbuserid,$bbusergroupid);

  if ($permissions[canreply]!=1) {

    eval("echo dovars(\"".gettemplate("karma_nopermission")."\");");

    exit;

  }



// ############################### Start Karma ###############################

if ($action=="karma") {

  //Make sure a user can't give karma on their own posts.

  if ($posterid==$bbuserid) {

    $points=$DB_site->query_first("Select karma from user where userid=$bbuserid");

    $karmicavg=$DB_site->query_first("SELECT SUM(rank) as netrank from karma where postid=$postid");

    $karmicbal=$karmicavg[netrank];

    $karma=$points[karma];

    if ($karmicbal>0) {

      $karmicmsg="Your Karma on this post is positive.";

    } elseif ($karmicbal<0) {

      $karmicmsg="Your Karma on this post is negative.";

    } elseif ($karmicbal==0 || $karmicbal==NULL) {

      $karmicmsg="There is no Karma on this post.";

    }

    eval("echo dovars(\"".gettemplate("karma_show")."\");");

    exit;

  }

  // Make Sure Karma is only given once per post.

  $karmaexists=$DB_site->query_first("Select count(*) as count from karma where userid=$bbuserid and postid=$postid");

  if ($karmaexists[count]<>0) {

    eval("echo dovars(\"".gettemplate("karma_exists")."\");");

    exit;

  }



  $userinfo=$DB_site->query_first("SELECT user.userid,post.userid as posterid,user.username as username

                                   FROM user LEFT JOIN post ON (user.userid = post.userid)

                                   WHERE post.postid=$postid");

  $postname=$userinfo[username];

  $posterid=$userinfo[posterid];

  $userid=$bbuserid;

  eval("echo dovars(\"".gettemplate("karma")."\");");

  exit;

}



// ############################### Update Karma ###############################

if ($action=="alter") {

 if ($comments=="No Comment") {

   $comments="";

 }



 $posterinfo=$DB_site->query_first("SELECT karma from user where userid=$posterid");

 $karma=$posterinfo[karma];

 $userinfo=$DB_site->query_first("SELECT posts from user where userid=$userid");

 $posts=$userinfo[posts];

 if ($posts > 1499)

   { $karmaaward=15; }

 elseif ($posts > 199)

   { $karmaaward=floor($posts/100); }

 else

   { $karmaaward=1; }



 $rank=0;

 if ($adjust=="praise")

   {$karma += $karmaaward;$rank += $karmaaward;}

 else

   {$karma -= $karmaaward;$rank -= $karmaaward;}

 if ($karma > $maxkarma)

   {$karma = $maxkarma;}

 if ($karma < $minkarma)

   {$karma = $minkarma;}

 $DB_site->query("UPDATE user SET karma=$karma where userid=$posterid");

 $DB_site->query("INSERT INTO karma (postid,userid,rank,comments,posterid) VALUES ($postid,$userid,$rank,'".addslashes($comments)."',$posterid)");

 //$DB_site->query("INSERT INTO karma (postid,userid,rank) VALUES ($postid,$userid,$rank)");

 eval("echo dovars(\"".gettemplate("karma_close")."\");");

 exit;

}



// ############################### Karma Help###############################

if ($action="help") {

    eval("echo dovars(\"".gettemplate("karma_help")."\");");

    exit;

  }



// ############################### View Comments ###############################

if ($action=="comments") {

  exit;

}

?>

Capitalist swine! :D

heh - I'm glad we had it cleared up, though.
Well, I guess it won't be hard to implement on your own - I guess I have to do it myself - tinker a bit with this perl code and the stars hack, I guess.

so can someone else do the karma hack and make it available for vB 2.0x ? if someone else could look at that php code and change it (if needed) and throw it into a zip and readme then distribute it as a hack.. that would be great!

Tic Tac

I'm not a PHP guru at all (just a few months of training) but a karma hack really cannot be THAT hard. I'll give it a shot. I'll develop it for my own site, but will do my best to make it easy to implement on others.

Can dis work for VB?Just curious....

Would it be possible to tailor that for a 2.0.1 vb? I'd really appreciate it since we're upgrading from a ubb with the karma hack, and we don't want the moderators to lose any power over reprimanding the members outside of their forum. If not, I understand, if so, I'd appreciate it.

Btw, where would you enter that code at, and in which file?

Thank you again:)

It could be editted for vB 2.0.1 but I have already stated that I don't have time to do it and my own "rewards" program is much mroe than a Karma hack and probably won't be released to the public.

This does require a database table and a few templates as well. The code above goes in its own file. This is different from the UBB hack though because it doesn't ban users and it is available to all members not just moderators.

I will be making this into a proper 2.0.1 hack, sooner or later. At the moment. I still have to figure out how the hell it works when you write a proper hack. You see, I'm still a little lost in vBulletin templates and core files, so it may take some time. I do intend to release it as a somewhat proper hack, though.

Can someone tell me how it works? What is the 'karma' hack? Do you get 'karma' for every post you make? Like a point system? If I knew the complete story I might be able to hack it...

thanks for the info wayne.. I will see what I can take from this code, and generate some new vb2.0.3 code :)

I think I get the idea of how to do this.
So em correct me if i'm wrong, I will wait a couple of hours before starting on it incase i have the wrong idea.

All posts start out as Karma Raiting 0, other users can rate the karma of a post once. Either negative or positive. Then is it the sum of all the posts that give a user a karma rating or is it the average karma for all posts.

The one bit that is semi confusing is the post count. Thats the one part I don't understand the point of.

I think it's a user rating...not a thread rating.
