Wordpress类别循环问题

Question

所以我在单词页面上设置了类别页面。但循环是用previous_post() php函数编写的，我无法弄清楚如何删除它而不会导致致命的php代码错误。下面是代码的推送。

    <?php
/**
* The template for displaying Category pages
 *
*/
 ?>
 <?php get_header(); ?>


    <div id="archive_content">

        <?php if ( have_posts() ) : ?>

        <?php
                // Start the Loop.
                while ( have_posts() ) : the_post(); {

                /*
                 * Include the post format-specific template for the content. If you want to
                 * use this in a child theme, then include a file called called content-___.php
                 * (where ___ is the post format) and that will be used instead.
                 */
                get_template_part( 'content', 'exchange-category' ); }

                endwhile;
                // Previous/next page navigation.
                 previous_post();

            else :
                // If no content, include the "No posts found" template.
                get_template_part( 'content', 'none' );

            endif;
        ?>
    </div><!-- #content -->
</section><!-- #primary -->

 <?php
     get_footer(); ?>

例如，如果您转到：http://www.bluestarnj.com/?it_exchange_category=d-bc，它会显示我查看的上一篇文章（产品）。我无法弄清楚如何正确设置循环，以便它所做的只是调用我的content-exchange-category.php页面，而wordpress codex以这种方式非常混乱。
