   Hi, I have found the code for the recent comments widget in the widgets.php file.

   What I would like to be able to do is change this code so that it will truncate the number of characters output for "comment author's" name. I have a lot of comments and lately, they are doing silly things like using names like "mindy in a bedazzled hot pink leather jacket in new jersey" as their comment author name and it is WACK.

   So, here is the code I need help with.

   function wp_widget_recent_comments($args) {
   	global $wpdb, $comments, $comment;
   	extract($args, EXTR_SKIP);
   	$options = get_option('widget_recent_comments');
   	$title = empty($options['title']) ? __('Recent Comments') : $options['title'];
   	if ( !$number = (int) $options['number'] )
   		$number = 5;
   	else if ( $number < 1 )
   		$number = 1;
   	else if ( $number > 15 )
   		$number = 15;
   
   	if ( !$comments = wp_cache_get( 'recent_comments', 'widget' ) ) {
   		$comments = $wpdb->get_results("SELECT comment_author, comment_author_url, comment_ID, comment_post_ID FROM $wpdb->comments WHERE comment_approved = '1' ORDER BY comment_date_gmt DESC LIMIT $number");
   		wp_cache_add( 'recent_comments', $comments, 'widget' );
   	}
   ?>
   
   		<?php echo $before_widget; ?>
   			<?php echo $before_title . $title . $after_title; ?>
   			<ul id="recentcomments"><?php
   			if ( $comments ) : foreach ($comments as $comment) :
   			echo  '<li class="recentcomments">' . sprintf(__('%1$s on %2$s'), get_comment_author_link(), '<a href="'. get_permalink($comment->comment_post_ID) . '#comment-' . $comment->comment_ID . '">' . get_the_title($comment->comment_post_ID) . '</a>') . '</li>';
   			endforeach; endif;?></ul>
   		<?php echo $after_widget; ?>
   <?php
   }

   I will buy you a nice beverage if you help. :)

   You probably have your situation figured out but I am posting this
   for anyone else that might look at this post.

   If wordpress already has a function like this and anyone has found
   it, please let me know.

   I modified a version of code taken from
   http://www.totallyphp.co.uk/code/shorten_a_text_string.htm
   "This will also round the text to the nearest whole word instead
   of cutting off part way through a word."

   I added the strip_tags function because when I used shorten_text(),
   it would cut the string half way through a html tag which leaves
   an open html tag when the page is rendered. (left the <p> tags in)

   This is a simplified version of what I have so hopefully it works.

   function shorten_text($text, $chars) {
   
   	$text = strip_tags($text, '<p>');	
   
   	$text = trim($text);
   
   	if(!$text){
   		return;
   	}
   	else{
   		if(!chars){
   			echo $text;
   		}
   		elseif($chars){
   
   			$text = $text." ";
   			$text = substr($text,0,$chars);
   			$text = $text."...";
   			echo $text;
   		}
   		else{
   			return;
   		}
   
   	}
   }
