wordpress获取随机文章的方法有很多，但我认为最好，最符合wordpress开发模式的是以下的代码：
<ul>
<?php
$args = array( 'numberposts' => 5, 'orderby' => 'rand', 'post_status' => 'publish' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
核心函数是$args = array( ‘numberposts’ => 5, ‘orderby’ => ‘rand’, ‘post_status’ => ‘publish’ );
