Replace the code you already have with this one:
function comment_plugger($show = 1, $limit = 0, $sep = ', ', $none = ' none') {
global $wpdb, $tablecomments, $id;
$cid = ($show) ? ($id - 1) : $id;
$request = "SELECT DISTINCT comment_author_url, comment_author FROM $tablecomments";
$request .= " WHERE comment_post_ID='$cid' AND comment_author <> '' AND comment_author_url <> ''";
$request .= ' ORDER BY comment_author ASC';
$request .= ($limit > 0) ? "LIMIT $limit" : '';
$commenters = $wpdb->get_results($request);
if ($commenters) {
$output = '';
foreach ($commenters as $commenter) {
if (!empty($commenter->comment_author_url)) {
$output[] = 'comment_author_url.'" title="'.$commenter->comment_author.'">'.$commenter->comment_author.'';
}
}
}
if (is_array($output)) {
echo implode($sep, $output);
} else {
echo $none;
}
}
It works…. Im using it.. Though I have problems now…
