WordPress添加面包屑导航功能

[tr][td]你在浏览某个分类下的文章的时候你想回到上面的目录，就需要用到面包屑导航，它主要用来记录你当前相对于文章首页的位置，他是一个相对位置。1，在functions.php中添加如下代码

function get_breadcrumbs(){global $wp_query;if ( !is_home() ){// Start the ULecho ' ';// Add the Home linkecho <span style="color: #0000ff;">'. get_settings('home') .'">'. 首页 .'';if ( is_category() ){$catTitle = single_cat_title( "", false );$cat = get_cat_ID( $catTitle );echo " » ". get_category_parents( $cat, TRUE, " » " ) ;}elseif ( is_archive() && !is_category() ){echo "» Archives";}elseif ( is_search() ) {echo "» Search Results";}elseif ( is_404() ){echo "» 404 Not Found";}elseif ( is_single() ){$category = get_the_category();$category_id = get_cat_ID( $category[0]->cat_name );echo '» '. get_category_parents( $category_id, TRUE, " » " );echo the_title('','', FALSE);}elseif ( is_page() ){$post = $wp_query->get_queried_object();if ( $post->post_parent == 0 ){echo " [*] » ".the_title('','', FALSE)."";} else {$title = the_title('','', FALSE);$ancestors = array_reverse( get_post_ancestors( $post->ID ) );array_push($ancestors, $post->ID);foreach ( $ancestors as $ancestor ){if( $ancestor != end($ancestors) ){echo <span style="color: #0000ff;">' [*] » . get_permalink($ancestor) .'">'. strip_tags( apply_filters( 'single_post_title', get_the_title( $ancestor ) ) ) .'';} else {echo ' [*] » '. strip_tags( apply_filters( 'single_post_title', get_the_title( $ancestor ) ) ) .'';}}}}// End the ULecho " ";}}

2，在需要调用的地方调用就好了

3，自己CSS美化一下吧
