什么是面包屑导航？看下下图就知道了。对于以内容为主，分类层次较多的站点来说，一个清晰的面包屑导航设计是非常重要的，因为它总能帮助用户在需要跳出的时候，如同灯塔一样迅速找到方向，所以快观察下你的网站是否有相关方面的考虑和设计，如果还没有面包屑导航的话，请结合自己的主题，按下面讲述的方法来实现wordpress文章面包屑导航.

具体方法，将下面的带代码增加到functions.php中。

/* 面包屑导航 */
function dimox_breadcrumbs() {
  $delimiter = '»';
  $name = '首页'; //text for the 'Home' link
  $currentBefore = '';
  $currentAfter = '';
  if ( !is_home() && !is_front_page() || is_paged() ) {
    echo '
您当前位于: ';
    global $post;
    $home = get_bloginfo('url');
    echo '' . $name . ' ' . $delimiter . ' ';
    if ( is_category() ) {
      global $wp_query;
      $cat_obj = $wp_query->get_queried_object();
      $thisCat = $cat_obj->term_id;
      $thisCat = get_category($thisCat);
      $parentCat = get_category($thisCat->parent);
      if ($thisCat->parent != 0) echo(get_category_parents($parentCat, TRUE, ' ' . $delimiter . ' '));
      echo $currentBefore . 'Archive by category '';
      single_cat_title();
      echo ''' . $currentAfter;
    } elseif ( is_day() ) {
      echo '' . get_the_time('Y') . ' ' . $delimiter . ' ';
      echo '' . get_the_time('F') . ' ' . $delimiter . ' ';
      echo $currentBefore . get_the_time('d') . $currentAfter;
    } elseif ( is_month() ) {
      echo '' . get_the_time('Y') . ' ' . $delimiter . ' ';
      echo $currentBefore . get_the_time('F') . $currentAfter;
    } elseif ( is_year() ) {
      echo $currentBefore . get_the_time('Y') . $currentAfter;
    } elseif ( is_single() ) {
      $cat = get_the_category(); $cat = $cat[0];
      echo get_category_parents($cat, TRUE, ' ' . $delimiter . ' ');
      echo $currentBefore;
      the_title();
      echo $currentAfter;
    } elseif ( is_page() && !$post->post_parent ) {
      echo $currentBefore;
      the_title();
      echo $currentAfter;
    } elseif ( is_page() && $post->post_parent ) {
      $parent_id  = $post->post_parent;
      $breadcrumbs = array();
      while ($parent_id) {
        $page = get_page($parent_id);
        $breadcrumbs[] = '' . get_the_title($page->ID) . '';
        $parent_id  = $page->post_parent;
      }
      $breadcrumbs = array_reverse($breadcrumbs);
      foreach ($breadcrumbs as $crumb) echo $crumb . ' ' . $delimiter . ' ';
      echo $currentBefore;
      the_title();
      echo $currentAfter;
    } elseif ( is_search() ) {
      echo $currentBefore . 'Search results for '' . get_search_query() . ''' . $currentAfter;
    } elseif ( is_tag() ) {
      echo $currentBefore . 'Posts tagged '';
      single_tag_title();
      echo ''' . $currentAfter;
    } elseif ( is_author() ) {
       global $author;
      $userdata = get_userdata($author);
      echo $currentBefore . 'Articles posted by ' . $userdata->display_name . $currentAfter;
    } elseif ( is_404() ) {
      echo $currentBefore . 'Error 404' . $currentAfter;
    }
    if ( get_query_var('paged') ) {
      if ( is_category() || is_day() || is_month() || is_year() || is_search() || is_tag() || is_author() ) echo ' (';
      echo __('Page') . ' ' . get_query_var('paged');
      if ( is_category() || is_day() || is_month() || is_year() || is_search() || is_tag() || is_author() ) echo ')';
    }
    echo '
';
  }
}

然和在页面的相应位置填写调用函数代码就可以了。
