    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              = '/';

            }
     
            echo '</ul>';  
        }
    }

    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;
    }
