之前大叔分享过一例 wordpress面包屑 的代码教程,详情可见:GO ?今天再分享一款更加细化的 wordpress面包屑导航,教程依然很简单,往functions.php加代码,然后前端调用即可,至于样式,自由发挥吧。代码如下:

breadcrumb

function?wpmomo_breadcrumb_html($post_id,$separator){?$path[]?=?wpmomo_breadcrumb_output(?home_url('/'),?'首页');?if(?get_post_type($post_id)=='post'?)?{?$cats_id?=?array();?$categories?=?get_the_category($post_id);?if($categories){?foreach($categories?as?$category)?{?if(!in_array($category->term_id,$cats_id)){?if?(?$category->parent?){?$path[]?=?wpmomo_get_category_parents(?$category->parent,?$separator?);?$cats_id[]?=?$category->parent;?}?$path[]?=?wpmomo_breadcrumb_output(?get_category_link(?$category->term_id?),?$category->name);?$cats_id[]?=?$category->term_id;?}?}?}?}?if(?is_singular()?&&?!is_single()?&&?!is_page()?){?$post_type?=?get_post_type();?$post_type_obj?=?get_post_type_object(?$post_type?);?$path[]?=?wpmomo_breadcrumb_output(?get_post_type_archive_link(?$post_type?),?$post_type_obj->labels->singular_name);?}?$path[]?=?wpmomo_breadcrumb_output(?get_permalink($post_id),?get_the_title($post_id));?echo?join(?$separator?,$path);?}?function?wpmomo_get_category_parents(?$id,?$separator='',?$visited?=?array()?)?{?$chain?=?'';?$parent?=?get_term(?$id,?'category'?);?if?(?is_wp_error(?$parent?)?)?return?$parent;?$name?=?$parent->name;?if?(?$parent->parent?&&?(?$parent->parent?!=?$parent->term_id?)?&&?!in_array(?$parent->parent,?$visited?)?)?{?$visited[]?=?$parent->parent;?$chain?.=?wpmomo_get_category_parents(?$parent->parent,?$separator,?$visited?);?}?$chain?.=?wpmomo_breadcrumb_output(?get_category_link(?$parent->term_id?),?$name);?return?$chain;?}function?wpmomo_breadcrumb_output($url,$name){?return?'<span">'.$name.'';?}

代码放进去后,下面就是在你的前端位置加入调用了,代码如下:

<?php?wpmomo_breadcrumb_html(get_the_ID(),'&nbsp??&nbsp');??>
