   Okay - gonna try and ask a question again...

   I'm trying to make a list of authors show up in my sidebar. Basically in the main content there will be a list of posts. In the sidebar, I want a duplicate loop but ONLY with the list of author names whose posts are displayed on that particular listing page.

   For example, say you have (in your settings) to display 5 posts per listing page. For example, say these 5 posts were written (in order) by admin, Richard, Richard, Mark and admin. In the sidebar, I put in a function that basically did a second loop, but had only the author names listed. However, it's listing the names multiple times, not just once:

   admin
   Richard
   Richard
   Mark
   admin

   What I want is :

   admin
   Richard
   Mark

   I'm really close to having this work, but I'm stuck on one final bit, and I was hoping someone could take a peek for me. Right now, I have the following code:

   $name = '';
   	$postlimit = get_option('posts_per_page');
   	$query = new WP_Query('showposts=' . $postlimit);
   	if($query->have_posts()) : while($query->have_posts()) : $query->the_post();
   	  $author = get_the_author();
   	  if($author != $name) {
   	    $name = $author;
   	    $count = '1';
   	  }
   	  if($count == '1') {
   	    get_my_image('avatar'); // this is another custom function
   	    echo $name . '<br />';
   	  }
   	  $count++;
   	endwhile;
   	endif;

   It's REALLY close, but the above lists:

   admin
   Richard
   Mark
   admin

   When I echo out the count, the final "admin" (the second one that shows up) is given a count of "1". It *should* be giving it "2", and thus not displaying it. Would anyone know what I could do to fix this? Any help would be appreciated.

   You could create an array, and for each author, see if they exist in the array already. If so, skip them. If not, add them to the array, and display it. Then you can also get rid of the current code you have in there thats comparing against the last author.

   So something like this:

   $postlimit = get_option('posts_per_page');
   $query = new WP_Query('showposts=' . $postlimit);
   $author_list = array();
   if($query->have_posts()) : while($query->have_posts()) : $query->the_post();
     $author = get_the_author();
     if (in_array($author, $author_list) == FALSE) {
       get_my_image('avatar'); // this is another custom function
       echo $name . '<br />';
       $author_list[] = $author;
     }
     $count++;
   endwhile;
   endif;

   Did you ever find a solution? I think I may need something similar here in the next few weeks.

   Yep - here it is:

   $root = $_SERVER['DOCUMENT_ROOT'];
   $path = get_bloginfo('home');
   function list_page_authors() {
   	global $post, $root, $path;
   
   	$output = array();
   	if(have_posts()) : while(have_posts()): the_post();
   	  $id = get_the_author_meta('ID');
   	  $id_arr[] = $id;
   	endwhile; endif;
   
       $clean = array_unique($id_arr);
       $count = '1';
   
       foreach($clean as $id) {
         $first = get_the_author_meta('first_name', $id);
         $last = get_the_author_meta('last_name', $id);
         $name = $first . ' ' . $last;
         $position = get_the_author_meta('position', $id);
         $description = get_the_author_meta('description', $id);
         $url = get_the_author_meta('user_url', $id);
         $img = '/wp-content/gravatars/' . $first . '_' . $last . '.jpg';
   
         if(file_exists($root . $img)) {
   	    $myimg  = '<img class="avatar" src="' . $path . $img . '" alt="' . $name . '" />';
         } else {
           $myimg = get_avatar( $post );
         } ?>
   
         <div class="authorinfo<?php if($count == '1') { echo ' first';} ?>">
       	<?php echo $myimg; ?>
       	<h5><?php echo $name;?></h5>
       	<h6><?php echo $position; ?></h6>
       	<p><?php echo $description; ?></p>
       	<?php if($url != '') { ?><a class="more-link" href="<?php echo $url; ?>">read more</a><?php } ?>
         </div>
   <?php $count ++;
         }
   }

   Hmm. Topic is now shown as "resolved" and there's no resolution posted. Weirdorama!

   That *is* weird - my post is right above yours...(I can see it)

   How bizarre.

   I think my method above is a bit shorter than that ;) But glad it works for you!

   prob'ly so :) But I also had to use this for other things as well - as it turned out, it's developed even further than this, and is way more complicated because of what I needed it for. Instead of boosting this one again, I'm going to be posting about the whole thing on my site - maybe making a plugin of my own on it.

   *believe me* - I looked at yours ;) I didn't want to code it all about if I didn't have to - but the requirements of the project made it necessary!
