How to Display Recently Registered Users in WordPress: Expert Guide with PHP & Shortcode

As a seasoned WordPress developer with years of experience building community-driven sites, I often recommend showcasing recently registered users to foster engagement. This works perfectly for multi-author blogs, membership sites, or forums where users register but aren't necessarily authors. Follow this proven tutorial to add a dynamic list of the newest members, complete with avatars and optional links to their websites.

Start by adding this reliable PHP function to your theme's functions.php file or a custom plugin to avoid theme update issues:

function wpb_recently_registered_users() {
    global $wpdb;
    $recentusers = '<ul>';
    $usernames = $wpdb->get_results("SELECT user_nicename, user_url, user_email FROM $wpdb->users ORDER BY ID DESC LIMIT 5");
    foreach ($usernames as $username) {
        if (!$username->user_url) {
            $recentusers .= '<li>'.get_avatar($username->user_email, 45).$username->user_nicename.'</li>';
        } else {
            $recentusers .= '<li>'.get_avatar($username->user_email, 45).'<a href="'.$username->user_url.'">'.$username->user_nicename.'</a></li>';
        }
    }
    $recentusers .= '</ul>';
    return $recentusers;
}

Now, embed the user list anywhere in your theme templates, such as sidebar.php or footer.php, using this simple call:

<?php echo wpb_recently_registered_users(); ?>

For flexibility without editing templates, create a shortcode by adding this line right after the function in functions.php:

add_shortcode('wpb_newusers', 'wpb_recently_registered_users');

Insert it in posts, pages, or widgets with: [wpb_newusers]. Customize the LIMIT in the SQL query or avatar size as needed for your site.
