Im列出所有作者列表的当前类别，但我想列出当前类别中的随机作者列表。

我尝试了“order”=>“RAND”，RAND代码不起作用。

我的代码：

function getCurrentCatID(){
  global $wp_query;
  if(is_category() || is_single()){
    $cat_ID = get_query_var(\'cat\');
  }
  return $cat_ID;
}

$current_category_ID = getCurrentCatID();
$current_cat_id = $current_category_ID;

$author_array = array();
$args = array(
  \'numberposts\' => -1,
  \'cat\' => $current_cat_id,
  \'orderby\' => \'author\',
  \'order\' => \'asc\',
  \'posts_per_page\' => \'10\',
);
$cat_posts = get_posts($args);

foreach ($cat_posts as $cat_post) :
  if (!in_array($cat_post->post_author,$author_array)) {
    $author_array[] = $cat_post->post_author;
  }
endforeach;

foreach ($author_array as $author) :
  $auth = get_userdata($author)->display_name;
  $auth_link = get_userdata($author)->user_login;
  $autid= get_userdata($author)->ID;
  $link = get_author_posts_url($autid);
  echo \'\'. get_avatar( $autid, \'46\' ).\'\';
  echo "<a class=\'sidebar-aut\' href=\'$link";
  echo "\'>";
  echo \'<h6>\'.$auth.\'</h6>\';
  echo "</a>";
  echo "<div class=\'clearfix\'></div>";
  echo "<br />";
endforeach;
