exclude roles from overview

Question

I am re-using some old code on a new website where I show all users in a listing with last post image as background. This all works fine (I know the get_users_of_blog is deprecated, but when I use get_users my code breaks)...

<?php
$blogusers = get_users_of_blog();
if ($blogusers) { 
  foreach ($blogusers as $bloguser) { 
    $args = array( 
      'author' => $bloguser->user_id, 
      'showposts' => 1,
      'caller_get_posts' => 1
    ); 
    $my_query = new WP_Query($args); 

    if( $my_query->have_posts() ) { 
      while ($my_query->have_posts()) : $my_query->the_post(); ?>  
        ...........
      <?php endwhile; 
    } 
  } 
} 
?> 

The thing is I can't get it ordered by name and exclude authors in the list. I tried doing this

$blogusers = get_users_of_blog(array('role' => 'editors', 'orderby => ID));

But this is not doing a darn thing. Anyone? Thank you!

Yes, the get_users_of_blog() function is deprecated, and the reason your code breaks after using get_users() is the ->user_id part, you should use ->ID instead.

$blogusers = get_users();

if ($blogusers) { 

  foreach ($blogusers as $bloguser) { 

    $args = array( 
      'author'           => $bloguser->ID, 
      'showposts'        => 1,
    ); 

    $my_query = new WP_Query($args); 

    if( $my_query->have_posts() ) { 
      while ($my_query->have_posts()) : $my_query->the_post(); ?>  
        ...........
      <?php endwhile; 
    } 

  } 

} 

If you are on a multisite, you should set the blog_id argument of get_users to your blog's ID.

Now, about excluding the authors. If you take a look at the author parameters of WP_Query(), there's a author__not_in argument that accepts an array of author IDs. So, to exclude the test role from your query, set the role__in or role argument of get_users() to test, and then use the results in your WP_Query(). You didn't provide accurate details so I'm not sure what exactly you are looking after, but these should do the trick.
