RiPro v2主题 – 给二级导航菜单添加文章数量统计与小圆点

美化说明：
RIPro-V2主题二级导航栏添加文章数量统计(同样也适用于别的主题)其它网站都收费,本站良心免费分享大家。
代码部署:
1.找到主题目录functions.php 文件，在最下面添加以下代码：

//导航菜单增加文章统计
function wt_get_category_count($cat_ID) {
    $category = get_category($cat_ID);
    return $category->count;
}
function lanmitu_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', 'lanmitu_nav_items_num',10,2 );

2.找到主题目录assetscssapp.css 在最下面添加以下CSS样式：

/*二级导航栏目统计*/
.num {
    position: absolute;
    top: 8px;
    left: 66%;
    color: #555;
    border-radius: 8px;
    text-align: center;
    font-family: Calibri;
    background: #eee;
    font-size: 12px;
    min-width: 32px;
}
	
/*二级导航前面小圆点*/
.hongse span {
  margin-left: 16px;
}

.hongse1 {
  box-sizing: border-box;
  content: '';
  width: 12px;
  height: 12px;
  border-radius: 50%;
  position: absolute;
  top: 50%;
  margin-left: 10px;
  margin-top: -6px;
  left: 1px;
  border-color: #61e1b9;
  border: 3px solid #7a99f2;
}

.hongse2 {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
    margin-left: 10px;
    margin-top: -6px;
    left: 1px;
    border-color: #61e1b9;
    border: 3px solid #70d7cf
}

.hongse3 {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
    margin-left: 10px;
    margin-top: -6px;
    left: 1px;
    border-color: #61e1b9;
    border: 3px solid #f5c745
}

.hongse4 {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
    margin-left: 10px;
    margin-top: -6px;
    left: 1px;
    border-color: #61e1b9;
    border: 3px solid #f1787f
}

调用方法:
在二级导航菜单添加小圆点,在后台-菜单里设置,如下图：

<div class="hongse"><div class="hongse1"></div><span>二级导航菜单名称</span></div>

注意：这里的”hongse1″对应的是上面CSS样式，一共4个样式，根据自己的爱好可以作相应的调整
