对于类别。php我的自定义查询代码没有显示正确类别中的帖子。

我有一个名为“博客”的父类别，它可以有任意数量的未知子类别。考虑到这一点，我正在尝试自动化我的循环，以便它能够检测类别并仅显示该类别的文章（即使其名称未知）。

<section id="posts">
    <div class="inner">

        <?php
        global $paged;
        global $post;
        $do_not_duplicate = array();
        $categories = get_the_category();
        $category = $categories[0];
        $cat_ID = $category->cat_ID;
        $myposts = get_posts(\'category=\'.$cat_ID.\'&paged=\'.$paged);
        $do_not_duplicate[] = $post->ID;
        $c = 0;
        ?>

        <?php foreach($myposts as $post) : setup_postdata($post); $c++;
            if( $c % 2 == 0) {
                $style = \'even animated fadeIn\';
                $c = 0;
            }
            else $style=\'animated fadeIn\'; ?>

            <article id="post-<?php the_ID(); ?>" <?php post_class($style) ?>>
                    <a class="article-block" href="<?php the_permalink(); ?>">
                    <?php if ( has_post_thumbnail() ) { ?>
