我创建了一个包含单个帖子的投资组合。查看帖子时，我想显示下一篇/前两篇帖子（公文包项目）。

目前我正在使用以下代码，但只显示一篇帖子：

<?php $prevPost = get_previous_post(true);
    if($prevPost) {?>
    <?php $prevthumbnail = get_the_post_thumbnail($prevPost->ID, array(114,114) );}?>
    <?php previous_post_link(\'%link\',"$prevthumbnail <h3>%title</h3>", TRUE ); ?>

我要创建以下内容：

[next post] | [next post] | [current post (active state)] | [previous post] | [previous post].

有人知道如何将其更改为工作代码吗？

这不是一个很好的方法，但很容易实现

global $post;
$original = $post;
$next = get_next_post(true);
$prev = get_previous_post(true);
$post = $next;
next_post_link();
$post = $original;
next_post_link();
// display current post
previous_post_link();
$post = $prev;
previous_post_link();
$post = $original;

为了提高代码的效率，可以从“wp includes/link template.php”中的核心代码中复制相应的函数；然后根据需要修改它们

在最基本的层面上get_adjacent_post, 改变LIMIT 1 到LIMIT 2 &；$wpdb->get_row 到$wpdb->get_results, 然后，直接/间接使用此功能的所有其他功能将相应更改

注意：不要更改核心代码，而是将函数复制到主题/插件，重命名，修改，然后使用新函数显示链接

get_previous_post() 和get_next_post() 两者都使用get_adjacent_post(). 该函数通过检查全局$post对象来确定下一个/上一个post。您可以更改$post 实现目标的目标：

$current_post = $post; // keep a copy of the current post;

$post = get_previous_post(false); 
echo $post->post_title;
$post = get_previous_post(false);
echo $post->post_title;

$post = $current_post;

$post = get_next_post(false); 
echo $post->post_title;
$post = get_next_post(false);
echo $post->post_title;

不得不把一些东西混在一起，但这是我的结果：

这对于更多想要用强大的下一个/上一个系统创建投资组合的人来说非常方便。

谢谢大家的帮助！
