之前模板下载吧分享过一例 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:
- 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(),' ›  '); ?>
