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 dulich_breadcrumb(){
if(!is_front_page()):
			$breadcrumb=array();
			//Home
			$breadcrumb_item=array(
				'url' => home_url(),
				'title' => __('Home','chilitheme')
			);
			array_push($breadcrumb,$breadcrumb_item);
			//at singular template
			if(is_singular() && !is_singular('product') && !is_page()):
				global $post;
				//Term
				$taxonomy_names = get_object_taxonomies($post);
				//var_dump(get_post_type());
				$term_arr=array();
				$terms = get_the_terms( $post->ID, $taxonomy_names[0] );
				if($terms): foreach ( $terms as $term ): 
					//get parent term top
					$term_parent_arr=get_ancestors($term->term_id,$taxonomy_names[0]);
					if($term_parent_arr): foreach($term_parent_arr as $item):
						$term_item = get_term($item,$taxonomy_names[0]);
						if($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_names[0]);
					$breadcrumb_item=array(
						'url' => get_term_link( (int) $term->term_id,$taxonomy_names[0]),
						'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' => __('Blog','chilitheme')
			);
			array_push($breadcrumb,$breadcrumb_item);
		endif;
		//at taxonomy template
		if((is_tax() || is_category()) && !is_
