分享一个WordPress面包屑导航代码

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:

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; }
