How to create a member directory

List your members (with published images) using the [ip-member-directory] shortcode. Copy the following snippet to your theme’s functions.php file:

add_shortcode('ip-member-directory', 'ip_member_directory');

function ip_member_directory_user_query($args) {
    $ip_slug = get_imagepress_option('ip_slug');
    $args->query_from = str_replace("post_type = post AND", "post_type IN ('$ip_slug') AND ", $args->query_from);
}

function ip_member_directory() {
    global $wpdb;

    $out = '';

    add_action('pre_user_query','ip_member_directory_user_query');
    $members = get_users(array(
        'fields' => array('ID', 'display_name'),
        'orderby' => 'post_count',
        'who' => 'authors',
        'has_published_posts' => get_post_types(array('public' => true)),
    ));
    remove_action('pre_user_query','ip_member_directory_user_query');

    $ipProfilePageId = (int) get_imagepress_option('ip_profile_page');
    $ipProfilePageUri = get_permalink($ipProfilePageId);
    $ipProfileSlug = (string) get_imagepress_option('cinnamon_author_slug');

    $out .= '<div>';
        foreach ($members as $group) {
            $ipProfileUri = $ipProfilePageUri . '?' . $ipProfileSlug . '=' . get_the_author_meta('user_login', $group->ID);
            $out .= '<div style="float:left;width:33%;">
                <a href="' . $ipProfileUri . '">' . $group->display_name . '</a>
            </div>';
        }
    $out .= '</div>';

    return $out;
}

Enjoy!
