我把这个循环放在一起，以显示所需猫的所有子帖子，但我没有从其中一个子猫那里得到任何帖子<不确定我是否在使用最佳方法来完成我正在尝试的事情。。

 <?php
        $posts = array();
         $categories = get_categories(\'child_of=5\');
         foreach($categories as $category) {
           $args=array(
            \'post_per_page\' => 5,
            \'orderby\' => \'post_date\',
            \'numberposts\' => 45,
            \'category__in\' => array($category->term_id)             
           );
         $posts = $posts + get_posts($args);
        } // Close your foreach here
             shuffle($posts);
              if ($posts) {
                foreach($posts as $post) {
                  setup_postdata($post);
                   ?>
                    <div <?php post_class(\'boxy\');?>><div  class="soc-label" ></div>

                  <?php 
                      if ( has_post_thumbnail()) {
                      $full_image_url =    wp_get_attachment_image_src( get_post_thumbnail_id(), \'full\');
                      echo \'<a href="\' . $full_image_url[0] . \'" rel="lightbox" title="\' . the_title_attribute(\'echo=0\') . \'" >\';
                      the_post_thumbnail(\'thumbnail\');
                      echo \'</a>\';
                    }
                   ?>

                    <?php the_content(\'\'); ?>
                    </div>


        <?php } 
           } 

        ?>

我在用同位素拼接的马赛克中使用这些结果，我正在对结果进行洗牌，这也是必须的。。如果有任何指导，我将不胜感激。过去几周，我一直在努力。

    <?php
        $posts = array();

            \'orderby\' => \'post_date\',
            \'numberposts\' => 40,
            \'category__in\' => array($category->term_id)             
           );
         $posts = array_merge($posts,get_posts($args));
        } // Close your foreach here
             shuffle($posts);
              if ($posts) {
                foreach($posts as $post) {
