I would also appreciate if you wrote something about whether you notice any difference in performance or not. A site with 10 posts/pages should not notice anything, but those of you with larger sites should see a difference.

function wordpress_wp_widget_recent_comments($args) {
global $wpdb, $comments, $comment, $current_user;
extract($args, EXTR_SKIP);
$options = get_option(’widget_recent_comments’);
$title = empty($options['title']) ? __(’Recent Comments’) : apply_filters(’widget_title’, $options['title']);
if ( !$number = (int) $options['number'] )
$number = 5;
else if ( $number < 1 )
$number = 1;
else if ( $number > 15 )
$number = 15;

if ( !$comments = wordpress_wp_cache_get( ‘recent_comments’, ‘widget’ ) ) {
$comments = $wpdb->get_results("SELECT * FROM $wpdb->comments WHERE comment_approved = ‘1′ AND comment_post_ID NOT IN (SELECT post_id FROM " . $wpdb->prefix . "named_users WHERE (user_id <> " . $current_user->ID . " OR group_id NOT IN (SELECT group_id FROM " . $wpdb->prefix . "named_users_groups_relations WHERE user_id = " . $current_user->ID . "))) ORDER BY comment_date_gmt DESC LIMIT $number");
wordpress_wp_cache_add( ‘recent_comments’, $comments, ‘widget’ );
}
?>

<?php echo $before_widget; ?>
<?php echo $before_title . $title . $after_title; ?>
<ul id="recentcomments"><?php
if ( $comments ) : foreach ( (array) $comments as $comment) :
echo ‘<li class="recentcomments">’ . sprintf(__(’%1$s on %2$s’), get_comment_author_link(), ‘<a href="’. get_comment_link($comment->comment_ID) . ‘">’ . get_the_title($comment->comment_post_ID) . ‘</a>’) . ‘</li>’;
endforeach; endif;?></ul>
<?php echo $after_widget; ?>
<?php
}

I’ve included a danish translation. Please write a comment if you want to share your translation files (.po and .mo) and remember to provide a link to the files, so that I can download them.

Remember to deactivate before upgrading as the database is upgraded when the plugin is activated!

I’ve made the group functionality so that it is possible to select users and groups who will have acces to posts/pages.  This means that you can go on the old way and give permissions to single users. You can also combine the two things and give permissions to a group and a couple of users.

“wpNamedUsers permissions” is not done yet, so it still behaves as if there were no groups.

Does it make sence?

I’ve started thinking about some kind of user management. I think it would be best, if it was possible to group users, so that it would be possible to set permissions to a group as well as individual users. Well, the “set permissions” has the highest priority at the moment, but I think that the grouping functionality would be nice to have.
