Wordpress calls multiple classifications to generate the code of homepage cms layout

The cms layout of wordpress home page needs to call multiple classified content. At the beginning, this code was borrowed from another topic. It uses the while loop, which I am not used to.

Later, I copied the foreach loop of zblog directly. I don't know whether it is correct or not. It works anyway ..

Share it and participate in politics with each other.

 <?php $themecateid = '1,2,3'; $flids = explode(',',$themecateid); foreach ($flids as $cid){ ?> <?php <ul> query_posts('posts_per_page=8&caller_get_posts=1&orderby=rand&cat='.$cid); while (have_posts()) : the_post(); echo '<li><a href="'.get_permalink().'" title="'.$post->post_title.'" target="_blank">'.$post->post_title.'</a></li>'; endwhile; wp_reset_query(); </ul> ?> <?php } ?>

The "1,2,3" of the above code is the classification ID of the call, and the while loop is still used for one layer. Html code structure can be adjusted at will.
