Bug in update_post_ul_meta?

if $lnumber is 0 in update_post_ul_meta (ldclite-function.php) then we hit this code

$sql=”insert into $table_name(post_id,ul_key,ul_value) values(‘$post_id’,’$up_type’,”.($lnumber+1).”);”;
if(isset($_COOKIE[‘ul_post_cnt’]))
{
$posts=$_COOKIE[‘ul_post_cnt’];
array_push($posts,$post_id);
foreach($posts as $key=>$value)
{
setcookie(“ul_post_cnt[$key]”,$for_com.$value, time()+1314000);
}
}

If $for_com is non-empty (i.e. it is “c_” because we are voting on a comment) then this prepends an extra “c_” to all the cookies. This will let people vote again. The code should match the replace case and look like this:

$sql="insert into $table_name(post_id,ul_key,ul_value) values('$post_id','$up_type',".($lnumber+1).");";
if(isset($_COOKIE['ul_post_cnt']))
{
    $posts=$_COOKIE['ul_post_cnt'];
    array_push($posts,$for_com.$post_id);
    foreach($posts as $key=>$value)
    {
        setcookie("ul_post_cnt[$key]",$value, time()+1314000);
    }
}

(Well actually that code should be refactored into another function to avoid the duplication of code and prevent copy/paste coding errors…)
