WordPress按分类显示文章 – WordPress 教程

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>';        }    }}?>
