wordpress单个文章页面的侧边栏如果还是显示和首页，分类页面一样的文章就没什么意思了。下面的代码是显示文章所属分类的文章列表，这样可以让访问者可以方便查看相关文章。回头再改改，看看能不能在分类页面上显示最受欢迎的文章。
添加下列代码在合时的位置即可
<?php
/*
single page?show current category articles
*/
?>
<?php
if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
?>
<li class="widget widget_recent_entries" id="<?php $category->term_id;?>-posts">
<h2 class="widgettitle"><?php echo $category->name; ?></h2>
<ul>
<?php
$posts = get_posts('numberposts=5&category='. $category->term_id);
foreach($posts as $post) :
?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
</li>
<?php
endforeach; endif ; ?>
<?php
/*
end show current category articles
*/
?>
/*
single page?show current category articles
*/
?>
<?php
if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
?>
<li class="widget widget_recent_entries" id="<?php $category->term_id;?>-posts">
<h2 class="widgettitle"><?php echo $category->name; ?></h2>
<ul>
<?php
$posts = get_posts('numberposts=5&category='. $category->term_id);
foreach($posts as $post) :
?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
</li>
<?php
endforeach; endif ; ?>
<?php
/*
end show current category articles
*/
?>

看一下
应该是用
$orderby 的 ‘rand’ – Randomly sort results.
改成类似这个样子你看看。
$posts = get_posts(‘numberposts=5&orderby=rand&category=’. $category->term_id);
参考http://codex.wordpress.org/Template_Tags/get_posts
如何改为显示当前类别的随机文章啊？
