我的作者列表现在基于帖子数量，我希望它基于最近活跃的用户。我的想法是尝试将orderby更改为post\\u date，但没有效果。对我如何做到这一点有什么建议吗？该列表需要包含用户照片。

<!-- users --> 
$allUsers = get_users(\'orderby=post_count&order=DESC\');

$users = array();

foreach($allUsers as $currentUser)
{
    if(!in_array( \'subscriber\', $currentUser->roles ))
    {
        $users[] = $currentUser;
    }
}

?>

<section class="content" role="main">
    <?php
        printf(\'<h1>%s</h1>\', the_title());

        foreach($users as $user)
        {
            ?>
            <div class="author">
                <div class="authorAvatar">
                    <?php echo get_avatar( $user->user_email, \'128\' ); ?>
                </div>
                <div class="authorInfo">
