WordPress按分类显示文章的方法

编辑:DEDE178模板网 / 2018-03-28 点击数:191
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>';
        }
    }
}
?>
