如何给wordpress增加导航路径
给wordpress增加导航路径，在文章中显示url路径的方法如下，只需在对应的主题的functions.php文件插入下面代码，然后再对应的主题页面添加<?php if (function_exists(‘moesora_breadcrumbs’)) moesora_breadcrumbs(); ?>这段代码就会达到在文章中显示导航路径的效果。
// end moesora_breadcrumbs()导航路径start
function moesora_breadcrumbs() {
$delimiter = ‘<span>»</span>’;
$before = ”; // tag before the current crumb
$after = ”; // tag after the current crumb
