我正在尝试从每个类别/分类中获取最新帖子的列表。我已经找到了解决方案，但我希望整个列表sorted by post date. 目前，它是按类别/分类名称排序的。

因此，如果我在A类中发帖，然后在B类中发帖，最后在C类中发帖：发帖顺序为：C、B、A（最新的在前）。如果我随后在cat B中发布，则顺序应更改为：B、C、A

我真的希望它能与自定义分类法一起使用，但默认类别也能适用于我。

到目前为止，我掌握的代码来自此网站：http://wptheming.com/2012/08/display-the-most-recent-post-in-each-category/

//Retrieves all the terms from the taxonomy portfolio_category
//http://codex.wordpress.org/Function_Reference/get_categories
$cat_args = array(
    \'type\' => \'post\',
    \'orderby\' => \'name\',
    \'order\' => \'ASC\',
    \'taxonomy\' => \'tax_name\');
$categories = get_categories( $cat_args );

    // Pulls the first post from each of the individual portfolio categories
    foreach( $categories as $category ) {
        $args = array(
            \'posts_per_page\' => 1,
            \'post_type\' => \'post\',
            \'tax_name\' => $category->slug,
            \'no_found_rows\' => true,
            \'update_post_meta_cache\' => false,
            \'update_post_term_cache\' => false
        );
        $the_query = new WP_Query( $args );

        // The Loop
        while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
            <div id="item">
                <b><?php the_title(); ?></b>
                <?php the_content(); ?>
            </div>
        <?php endwhile;
        }
    // Reset Post Data
    wp_reset_postdata();
    ?>

编辑：我尝试编辑代码的第一部分以：

$cat_args = array(
    \'type\' => \'post\',
    \'orderby\' => \'date\',
    \'order\' => \'DESC\',
    \'taxonomy\' => \'tax_name\');
$categories = get_categories( $cat_args );

但它仍然按照分类名称的顺序显示帖子？

$cat_args = array(
    \'type\' => \'post\',
    \'orderby\' => \'name\',
    \'order\' => \'ASC\',
    \'taxonomy\' => \'tax_name\');
$categories = get_categories( $cat_args );

$cat_args = array(
    \'type\' => \'post\',
    \'orderby\' => \'date\',
    \'order\' => \'DESC\',
    \'taxonomy\' => \'tax_name\');
$categories = get_categories( $cat_args );
