Authors list Pagination?

Question

WordPress has a built in function to display a list of all of your site’s authors. But there is no option to display their avatars, so all you really get is a text list that links to the author’s page, if you have an author.php file in your theme, that is.

thus turning the internet I found this nice tutorial bavotasan.com with a little piece of code that seems to do the trick.

On my site all users can write articles and list of contributors is long. It’s possible set 10 users for page ?

Using this solution: Paginate result set from $wpdb->get_results()

I did make my code for Authors list functions as follow:

    function contributors() {
global $wpdb;

$authors = $wpdb->get_results("SELECT ID, user_nicename from $wpdb->users WHERE display_name <> 'admin' ORDER BY display_name");

$authors_per_page = 10;
$page = isset( $_GET['cpage'] ) ? abs( (int) $_GET['cpage'] ) : 1;

echo paginate_links( array(
    'base' => add_query_arg( 'cpage', '%#%' ),
    'format' => '',
    'prev_text' => __('«'),
    'next_text' => __('»'),
    'total' => ceil($total / $authors_per_page),
    'current' => $page
));

foreach ($authors as $author ) {

echo "<li>";
echo "<a href=\"".get_bloginfo('url')."/author/";
the_author_meta('user_nicename', $author->ID);
echo "/\">";
echo get_avatar($author->ID);
echo "</a>";
echo '<div>';
echo "<a href=\"".get_bloginfo('url')."/author/";
the_author_meta('user_nicename', $author->ID);
echo "/\">";
the_author_meta('display_name', $author->ID);
echo "</a>";
echo "<br />";
echo "SitoWeb: <a href=\"";
the_author_meta('user_url', $author->ID);
echo "/\" target='_blank'>";
the_author_meta('user_url', $author->ID);
echo "</a>";
echo "<br />";
echo "Twitter: <a href=\"http://twitter.com/";
the_author_meta('twitter', $author->ID);
echo "\" target='_blank'>";
the_author_meta('twitter', $author->ID);
echo "</a>";
echo "<br />";
echo "<a href=\"".get_bloginfo('url')."/author/";
the_author_meta('user_nicename', $author->ID);
echo "/\">Visita il Profilo di ";
the_author_meta('display_name', $author->ID);
echo "</a>";
echo "</div>";
echo "</li>";
}
}

but still does the trick ..... Please help me to find out the error and its rectification. Thanks a lot.

I have modified WP_LIST_AUTHORS to paginate. I don't know if its very sexy, and seems to require some sort of Caching plugin otherwise this particular page can start to load pretty slowly.

The full code of my paginated function is in this thread: Modifying WP_LIST_AUTHOR Functions to output all users in a grid (and Paginate)

If you just want to look directly at the pagination code I used you can go here: http://www.phpfreaks.com/tutorial/basic-pagination

In your case you can save your time the trouble by using Members List Plugin

which allows you to create a post on your wordpress blog that lists all your wordpress members. When viewing the list of members you can also search through your members according to first name, last name, email address, URL or any other number of user meta fields you may specify. Employing pagination you can page through your search results and sort your results according to last name, first name, registration date or email.

if I add this code as I recall it in the loop?

// Get the current page
$paged = get_query_var('paged');
if (!$paged) $paged = 1;

// We'll return these at a later stage
$current_page = $paged;
$total_pages = ceil(count($authors) / 10);

// Calculate the starting and ending points
// Assuming we'll be showing 10 authors per page
$start = ($paged - 1) * 10;
$end = $paged * 10;
if ($end > count($authors)) $end = count($authors);
