php - php代码有问题按类别过滤帖子

Question

我是 php 新手并尝试制作一个 wordpress 主题，帮助我转换此代码，而不是按主题过滤最新帖子以按类别过滤帖子，我一直在尝试更改它几个小时，但它似乎没有工作

代码如下，我基于另一个主题非常好，但是此代码仅获取从所有类别聚合的最新帖子，如果我想获取特定类别的最新帖子，我应该如何更改它？

<?php if ( ! is_paged() ) {

                    $category_id = $section['mts_featured_category'];
                    $featured_category_layout = $section['mts_featured_category_layout'];
                    $posts_num = $section['mts_featured_category_postsnum'];
                    if ( $category_id === 'latest' && ! $latest_posts_used ) {
