我使用以下代码计算作者数

    $count_posts = wp_count_posts( \'download\' );
    echo \'Published eBook (\' . $count_posts->publish .  \')\';
    echo \' \';
    global $wpdb; 
    $user_count = $wpdb->get_var( "SELECT COUNT(*) FROM $wpdb->users;" );
    echo \'  Published Authors (\' . $user_count . \')\';

我需要一个从谁的角色前端供应商或谁已经发表了downlaod文章作者计数。

有什么想法吗？谢谢你的帮助

$args = array(
\'role\' => \'frontend_vendor\',//substitute your role here as needed
\'fields\' => \'ID\',
);

$users = get_users( $args );
$user_count = count( $users );
