wordpress上下篇文章自定义链接格式

在wordpress网站文章页中常常需要用到上下篇文章，但是默认的调用方式不好修改链接格式，

今天给大家提供一个简单的代码解决这个问题。

默认的调用代码;

<?php previous_post_link('%link','<<') ?>
<?php next_post_link('%link','>>') ?>

1 2	<?php previous_post_link('%link','<<') ?> <?php next_post_link('%link','>>') ?>

默认的调用代码没法自定义链接，我们可以用下面代码来替代

<?php
$prev_post = get_previous_post();
if (!empty( $prev_post )): ?>
  <a title="<?php echo $prev_post->post_title; ?>" href="<?php echo get_permalink( $prev_post->ID ); ?>" 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 echo get_permalink( $next_post->ID ); ?>" rel="external nofollow" ><?php echo $next_post->post_title; ?></a>
<?php endif; ?>

<?php

$prev_post = get_previous_post();

if (!empty( $prev_post )): ?>

<a title="<?php echo $prev_post->post_title; ?>" href="<?php echo get_permalink( $prev_post->ID ); ?>" 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 echo get_permalink( $next_post->ID ); ?>" rel="external nofollow" ><?php echo $next_post->post_title; ?></a>

<?php endif; ?>

通过这个代码我们可以自定义上下篇的链接结构，也可以单独调用上下篇文章的标题和链接，非常方便！
