WordPress随机文章-昊天SEO

foreach 遍历数组实现随机文章

<?php
$rand_posts = get_posts("numberposts=10&orderby=rand");
foreach( $rand_posts as $post ) :
?>
<!--下面是你想自定义的Loop-->
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

<?php

$rand_posts = get_posts("numberposts=10&orderby=rand");

foreach( $rand_posts as $post ) :

<?php endforeach; ?>

有些情况下，get_posts会失效。比如我把随机文章的函数放在某个.php文件中，然后通过include来调用，循环显示的不是随机文章，而是全部相同的文章。

只要全局声明下即可，代码如下

<ul>
<?php
global $post;
$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; ?>
</ul>
