下面由wordpress教程栏目给大家分享一个wordpress面包屑导航代码，希望对需要的朋友有所帮助！
转载分享一段WordPress面包屑导航代码，支持自定义帖子类型、自定义分类，但貌似在分类归档页面不能显示父子分类层级有点遗憾。
将代码添加到当前主题函数模板functions.php中：
/**
* WordPress Breadcrumbs
*/
function tsh_wp_custom_breadcrumbs() {
$separator = '/';
$breadcrumbs_id = 'tsh_breadcrumbs';
$breadcrumbs_class = 'tsh_breadcrumbs';
$home_title = esc_html__('Home', 'your-domain');
// Add here you custom post taxonomies
$tsh_custom_taxonomy = 'product_cat';
global $post,$wp_query;
// Hide from front page
if ( !is_front_page() ) {
echo '
- ';
// Home
echo '
- ' . $home_title . ' '; echo '
- ' . $separator . ' '; if ( is_archive() && !is_tax() && !is_category() && !is_tag() ) { echo '
- ' . post_type_archive_title('', false) .

将调用代码放到主题模板适当位置比如header.php中：
<?php if (function_exists('tsh_wp_custom_breadcrumbs')) tsh_wp_custom_breadcrumbs(); ?>
配套样式：
#tsh_breadcrumbs .separator{
font-size:20px;
color:#ccc;
font-weight:100;
}
#tsh_breadcrumbs{
overflow:hidden;
text-align: center;
list-style:none;
margin:11px 0;
}
#tsh_breadcrumbs li{
margin-right:14px;
display:inline-block;
vertical-align:middle;
}
