您可以使用per_get_posts 筛选器挂钩可更改查询的顺序，例如：

add_filter(\'pre_get_posts\', \'filter_homepage_posts_order\');
function filter_homepage_posts_order($query) {
    //only run is current page is home page
    if ($query->is_home) {
        $limit_number_of_posts = 5; //number of posts 
        $featured_category_id = get_cat_id(\'Reviews\'); // by cat name...
        $query->set(\'cat\', $featured_category_id);
        $query->set(\'posts_per_page\', $limit_number_of_posts);
        $query->set(\'order\',\'DESC\')
    }
  return $query;
}
