可以自动将WordPress站点的文章按分类显示在一个页面中，用作CMS主题布局很实用。

用下代码替换首页模板主循环，则按分类显示各分类最新的5篇文章。

<?php

global $cat;

$cats = get_categories(array(

'child_of' => $cat,

'parent' => $cat,

'hide_empty' => 0

));

$c = get_category($cat);

foreach($cats as $the_cat){

$posts = get_posts(array(

'category' => $the_cat->cat_ID,

'numberposts' => 5,

));

if(!empty($posts)){

echo '

<div class="item cat_item">

<div class="item_title"><h2><a title="'.$the_cat->name.'" href="'.get_category_link($the_cat).'">'.$the_cat->name.'</a></h2></div>

<ul class="box_list">';

foreach($posts as $post){

echo '<li><span class="alignright">'.mysql2date('Y-m-d', $post->post_date).'</span>

<a title="'.$post->post_title.'" href="'.get_permalink($post->ID).'">'.$post->post_title.'</a></li>';

}

echo '</ul>

</div>';

}

}

?>

用下代码替换分类归档模板主循环，则显示该分类下所有子分类的最新5篇文章，并按分类显示。如果当前分类下不存在子分类，则显示该分类的文章列表！

<?php

global $cat;

$cats = get_categories(array(

'child_of' => $cat,

'parent' => $cat,

'hide_empty' => 0

));

$c = get_category($cat);

if(empty($cats)){

?>

<div class="item">

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

<div class="post">

<h2><a title="<?php the_title(); ?>" href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>

<p><?php the_excerpt(); ?></p>

<p><a href="<?php the_permalink(); ?>">全文阅读>></a></p>

<div class="meta"><?php the_time('Y-m-d'); ?> | 标签: <?php the_tags('', ' , ', ''); ?></div>

</div>

<?php endwhile; ?>

<?php else: ?>

<div class="post"><p>文章稍后更新</p></div>

<?php endif; ?>

</div>

<div class="navigation">

<span class="alignleft"><?php next_posts_link('&laquo; Older posts') ?></span>

<span class="alignright"><?php previous_posts_link('Newer posts &raquo;') ?></span>

</div>

<?php

}else{

foreach($cats as $the_cat){

$posts = get_posts(array(

'category' => $the_cat->cat_ID,

'numberposts' => 10,

));

if(!empty($posts)){

echo '

<div class="item cat_item">

<div class="item_title"><h2><a title="'.$the_cat->name.'" href="'.get_category_link($the_cat).'">'.$the_cat->name.'</a></h2></div>

<ul class="box_list">';

foreach($posts as $post){

echo '<li><span class="alignright">'.mysql2date('Y-m-d', $post->post_date).'</span>

<a title="'.$post->post_title.'" href="'.get_permalink($post->ID).'">'.$post->post_title.'</a></li>';

}

echo '</ul>

</div>';

}

}

}

?>
