Breadcumb (thanh điều hướng) là một chức năng hầu như website nào cũng phải có. Hôm nay tôi sẽ chia sẽ với anh chị đoạn code tạo breadcrumb trên mọi page, anh chị chỉ cần đêm nó về rồi build html của thanh breadcrumb mà thôi

php code

function breadcrumb(){
		if(!is_front_page()):
				$breadcrumb=array();
				//Home
				$breadcrumb_item=array(
					'url' => home_url(),
					'title' => __('Trang chủ','chilitheme')
				);
				array_push($breadcrumb,$breadcrumb_item);
				//at singular template
				if(is_singular()  && !is_page()):
					global $post;
					//Term
					$taxonomy_names = get_object_taxonomies($post);
					//var_dump(get_post_type());
					$term_arr=array();
					if(is_singular('product')){
						$taxonomy =  'product_cat';
					}else{
						$taxonomy =  $taxonomy_names[0] ;
					}
					//var_dump($taxonomy);
					$terms = get_the_terms( $post->ID, $taxonomy );
					//var_dump($terms[0]->term_id);	
					if($terms): foreach ( $terms as $term ): 
						//get parent term top
						$term_parent_arr=get_ancestors($term->term_id,$taxonomy);
						if($term_parent_arr): foreach($term_parent_arr as $item):
							$term_item = get_term($item,$taxonomy);
							if($term_item->parent == 0):
								array_push($term_arr,$item);
								break;
							endif;
						endforeach; endif;
						array_push($term_arr,$term->term_id);
					endforeach; endif;	
					$term_arr = array_unique($term_arr);
					if($term_arr): foreach($term_arr as $item):
						$term = get_term($item,$taxonomy);
						$breadcrumb_item=array(
							'url' => get_term_link( (int) $term->term_id,$taxonomy),
							'title' => $term->name
						);
						array_push($breadcrumb,$breadcrumb_item);
					endforeach; endif;	
					//singular
					$breadcrumb_item=array(
						'url' => get_permalink($post->ID),
						'title' => $post->post_title
					);
					array_push($breadcrumb,$breadcrumb_item);	
						
			endif;	
			//page
			if(is_page()):
				global $post;
				$breadcrumb_item=array(
						'url' => get_permalink($post->ID),
						'title' => $post->post_title
					);
				array_push($breadcrumb,$breadcrumb_item);	
			endif;
			//blog
			if(is_home()):
				$page_for_posts=get_option('page_for_posts');
				$breadcrumb_item=array(
					'url' => get_permalink($page_for_posts),
					'title' => __('Tin tức')
				);
				array_push($breadcrumb,$breadcrumb_item);
			endif;
			//at taxonomy template
			if((is_tax() || is_category())):
				global $wp_query;
				$term = $wp_query->get_queried_object();
				$term_arr=array();
				//echo "<pre>";
				//print_r($wp_query->queried_object->taxonomy);
				//echo "</pre>";
				//get parent term top
				//$taxonomy_names = get_object_taxonomies(array('post','product'));
				//var_dump($taxonomy_names);
				$term_parent_arr=get_ancestors($term->term_id,$wp_query->queried_object->taxonomy);
				if($term_parent_arr): foreach($term_parent_arr as $item):
					$term_item = get_term($item,$wp_query->queried_object->taxonomy);
					if($term_item->parent == 0):
						array_push($term_arr,$item);
						break;
					endif;
				endforeach; endif;
				array_push($term_arr,$term->term_id);
				$term_arr = array_unique($term_arr);
				if($term_arr): foreach($term_arr as $item):
					$term = get_term($item,$wp_query->queried_object->taxonomy);
					$breadcrumb_item=array(
						'url' => get_term_link( (int) $term->term_id,$wp_query->queried_object->taxonomy),
						'title' => $term->name
					);
					array_push($breadcrumb,$breadcrumb_item);
				endforeach; endif;	
			endif;
			if(is_post_type_archive()):
				$get_current_post_type=get_post_type();
				$archive=get_post_type_object($get_current_post_type);
				//var_dump($archive);
				$breadcrumb_item=array(
						'url' => get_post_type_archive_link($get_current_post_type),
						'title' => $archive->labels->menu_name
				);
				array_push($breadcrumb,$breadcrumb_item);
			endif;
		endif;	
	 	//var_dump($breadcrumb);
		if($breadcrumb):
			?>
		  
			<div class="breadcrumb">
			<?php $i=1; foreach($breadcrumb as $item):?>
			<?php if($i == 1){ ?>
