RIPRO-V2主题美化添加二级菜单统计显示

方法很简单和ripro主题一样，直接在主题目录下functions.php文件中添加以下代码

//导航栏目统计
function wt_get_category_count($cat_ID) {
	$category = get_category($cat_ID);
	return $category->count;
}
function nav_items_num( $items,$args ) {
	if(isset($args->theme_location) && $args->theme_location == 'menu-1') {
		foreach ( $items as $key=>$item ) {
			if($item->object == 'category') {
				//$cat = get_category_by_slug($slug);
				$catID = isset($item->object_id) ? $item->object_id : false;
				if($catID && $item->post_parent!=0) {
					$a=wt_get_category_count($catID);
					$items[$key]->title.= '<span class="num">'.$a.'</span>';
				}
			}
		}
	}
	return $items;
}
add_filter( 'wp_nav_menu_objects', 'nav_items_num',10,2 );

再将CSS代码粘贴到app.css文件保存

/*导航栏目统计*/
.num{position:absolute;top:8px;left:75%;color:#555;border-radius:8px;text-align:center;font-family:Calibri;background:#eee;font-size:12px;min-width:32px}

粘贴保存后即可实现二级菜单统计功能
