面包屑子类别链接丢失

Question

我不使用面包屑插件。这对我来说没问题。我检查了类别父母。一切都好。但出了点问题，

我有一个类别和子类别。

像这样：

BCD - 类别

xyz - 子类别

你好 - 帖子标题。

代码输出：

首页> BCD码您好（子类别在哪里？）

子类别丢失。

但如果子类别名称以 A 字符开头 例如 abc

代码输出：

首页 > BCD码abc>你好

我也遇到了这个问题，所以这是我修改来解决这个问题的代码...

  function wordpress_breadcrumbs() {

     $delimiter = '';
     $name = 'Home'; //text for the 'Home' link
     $currentBefore = '<li>';
     $currentAfter = '</li>';

  if ( !is_home() && !is_front_page() || is_paged() ) {

echo '<ul id="crumbs">';

global $post;
$home = get_bloginfo('url');
echo '<li><a href="' . $home . '">' . $name . '</a></li> ' . $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 ($thisCat->parent != 0) echo '<li>' .(get_category_parents($parentCat, TRUE, ' ' . $delimiter . ' ')) ;
  echo $currentBefore ;
  echo single_cat_title();
  echo $currentAfter;

} elseif ( is_day() ) {
  echo '<li><a href="' . get_year_link(get_the_time('Y')) . '">' . get_the_time('Y') . '</a></li> ' . $delimiter . ' ';
  echo '<li><a href="' . get_month_link(get_the_time('Y'),get_the_time('m')) . '">' . get_the_time('F') . '</a></li> ' . $delimiter . ' ';
  echo $currentBefore . get_the_time('d') . $currentAfter;

} elseif ( is_month() ) {
  echo '<a href="' . get_year_link(get_the_time('Y')) . '">' . get_the_time('Y') . '</a></li> ' . $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 = $cat[0];
  echo '<li>' .get_category_parents($cat, FALSE, ' <li>' . $delimiter . '');
  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);
    $breadcrumbs[] = '<a href="' . get_permalink($page->ID) . '">' . get_the_title($page->ID) . '</a>';
    $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 '</ul>';

   }
  }

要调用它，只需放入

   <?php if (function_exists('wordpress_breadcrumbs')) wordpress_breadcrumbs(); ?>
