您不应该使用query_posts 完全一切都在this post 我最近做过。查看我在那篇文章中给出的所有链接

分页不起作用的一个大问题是默认的二十一分页函数，twentytwelve_content_nav, 不提供自定义查询。但是，您可以重写此函数，因为它被包装在if ( ! function_exists() ) 条件语句。

首先，用于自定义查询。如前所述，不要也永远不要使用query_posts, 大多数情况下，它在分页时完全失败。这是你要用的WP_Query. 因此，请将您的页面模板更改为以下内容（这里只有一点，category_name 使用类别slug, 不name)

<?php
/*
Template Name: C Programming Category page
*/

get_header(); ?>

    <div id="primary" class="site-content">
        <div id="content" role="main">

        <?php
        $args = array(
            \'category_name\' => \'c-programming\'
        );

        $my_query = new WP_Query($args); ?>
        <?php if ( $my_query->have_posts() ) : ?>

            <?php /* Start the Loop */ ?>
            <?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
                <?php get_template_part( \'content\', \'custom\' ); ?>
            <?php endwhile; ?>

            <?php twentytwelve_content_nav( \'nav-below\' ); ?>

        <?php else : ?>

            <article id="post-0" class="post no-results not-found">

            <?php if ( current_user_can( \'edit_posts\' ) ) :
                // Show a different message to a logged-in user who can add posts.
            ?>
                <header class="entry-header">
                    <h1 class="entry-title"><?php _e( \'No posts to display\', \'twentytwelve\' ); ?></h1>
                </header>

                <div class="entry-content">

                </div><!-- .entry-content -->

            <?php else :

                </div><!-- .entry-content -->
