Zen-cart产品页面随机调用Wordpress文章

<?php require('./wordpress所在目录/wp-blog-header.php'); ?>
<?php
$rand_posts = get_posts('numberposts=5&orderby=rand');
foreach( $rand_posts as $post ) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

注：$rand_posts = get_posts('numberposts=5&orderby=rand');这里的5指调用随机文章数量
