如果要显示类别帖子列表，可以使用自定义循环，如下所示：

<?php

    $paged = (get_query_var(\'paged\')) ? get_query_var(\'paged\') : 1;

    $query_args = array(
               \'posts_per_page\' => 5,
               \'category_name\' => \'foo\',
               \'paged\' => $paged
    );

    $the_query = new WP_Query($query_args);

    if ($the_query->have_posts()) : while ($the_query->have_posts()) :  
             $the_query->the_post(); ?>

              <?php // any other template tag ?>

              <?php the_title(); ?>

              <?php the_post_thumbnail(); ?>

               <?php the_excerpt(); ?>

<?php endwhile; endif; ?>

<div class="navigation">
           <div class="alignleft"><?php next_posts_link(\'&larr; Older Entries\') ?></div>
           <div class="alignright"><?php previous_posts_link(\'Newer Entries &rarr;\') ?></div>
</div><!-- /.navigation -->

<?php wp_reset_query(); ?>

只需在查询中指定类别id

$args = array(
\'cat\'      => 22,
\'order\'    => \'ASC\'
);
query_posts( $args );
