<?php previous_post_link('%link','<<') ?>
<?php next_post_link('%link','>>') ?>
該程式碼解析出來的程式碼大概如下：
<a href="……" rel="external nofollow" rel="external nofollow" > …… </a>
<a href="……" rel="external nofollow" rel="external nofollow" > …… </a>
透過 get_previous_post 、 get_next_post 這兩個函式我們可以獲取到上一篇和下一篇文章的相關資訊 （大家可以到官網看看這兩個函式的介紹） 。
具體解決方法如下：
將
<?php previous_post_link('%link','<<') ?>
<?php next_post_link('%link','>>') ?>
替換為
<?php
$prev_post = get_previous_post();
if (!empty( $prev_post )): ?>
<a title="<?php echo $prev_post->post_title; ?>"
href="<?php%20echo%20get_permalink(%20$prev_post->ID%20);%20?>"
rel="external nofollow" ><?php echo $prev_post->post_title;
?></a>
<?php endif; ?>
<?php
$next_post = get_next_post();
if (!empty( $next_post )): ?>
<a title="<?php echo $next_post->post_title; ?>"
href="<?php%20echo%20get_permalink(%20$next_post->ID%20);%20?>"
rel="external nofollow" ><?php echo $next_post->post_title;
?></a>
<?php endif; ?>
