WordPress按分类显示文章

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>\';
        }
    }
}
?>
