simple tags1.1提供了一个函数，st_related_posts(””);这个函数可以添加在文章的结尾处，根据这篇文章的tags，来获取与之相同tags的一组文章的标题列表，从而能帮助读者快速的找到相关信息。
在管理后台，即标签-选项中，我们可以复选此功能，但会在主页面，单个文章页面，文章后都会出现这个相关日志列表，那么，怎么自己添加这个函数呢？我们以只在单个文章下添加为例。

一般的主题文件，simple.php控制着单个页面的显示，打开 single.php，找到文章的结尾处添加
<?php st_related_posts(‘number=10&title=&include_page=false&xformat=<a href=”%permalink%” title=”%title% (%date%)”>%title%</a>’); ?>即可。具体的函数值参考下面，或是作者的主页。

而有些不是在single.php下 添加，如我用的k2,是在theloop.php下控制的。

找到

<div class=”entry-content”>
<?php the_content(sprintf(__(’Continue reading \’%s\”, ‘k2_domain’), the_title(”, ”, false))); ?>

<?php wp_link_pages(’before=<p class=”page-links”><strong>’ . __(’Pages:’,’k2_domain’) . ‘</strong>&after=</p>’); ?>

<?php if ((is_single() or is_day()) ) { ?>
<?php st_related_posts(’number=10&title=相关文章&nopoststext=暂时没

有 :(&include_page=false&xformat=<a href=”%permalink%” title=”%title% (%date%)”>%title%</a>’); ?>
<?php } ?>

</div> <!– .entry-content –>

删除线所标志的，即为我添加的。大家可以试试。

函数:

1. <?php st_related_posts(“”); ?>

函数值:

1. ‘number’ => 5,

2. ‘orderby’ => ‘counter’,

3. ‘order’ => ‘DESC’,

4. ‘format’ => ‘list’,

5. ‘include_page’ => true,

6. ‘exclude_posts’ => ”,

7. ‘exclude_tags’ => ”,

8. ‘title’ => __(‘<h4>Related posts</h4>’, ’simpletags’),

9. ‘nopoststext’ => __(‘No related posts.’, ’simpletags’),

10. ‘dateformat’ => $this->dateformat,

11. ‘xformat’ => __(‘<a href=”%permalink%” title=”%title% (%date%)”>%title%</a> (%commentcount%)’, ’simpletags’)

举例:

We want to show the first 10 related article without title, without pages and without comments count.

1. <?php st_related_posts(‘number=10&title=&include_page=false&xformat=<a href=”%permalink%” title=”%title% (%date%)”>%title%</a>’); ?>

应该说1.1版本有了比较明显的提升，因为可以根据tags的相关性来判断生成一个相关日志列表了。所以就不用以前的一些显示相关日志的插件了，一个simple tags足矣。
