wordpress美化 ripro主题美化 给二级导航菜单添加文章数量统计和美化小圆点

ripro美化教程提到给导航菜单栏添加角标文字，今天教大家给ripro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)

先看下效果图：

1、找到\ripro\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\ripro\assets\css\diy.css 在最下面添加以下CSS样式：

/**二级菜单文章统计**/
.num {
	position: absolute;
	top: 8px;
	left: 68%;
	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***/
.lanse {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
	margin-left: 10px;
    margin-top: -6px;
    left: 0;
	border-color: #61e1b9;
	border: 3px solid #7a99f2;
}

.lvse {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
	margin-left: 10px;
    margin-top: -6px;
    left: 0;
	border-color: #61e1b9;
	border: 3px solid #70d7cf;
}
.huangse {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
	margin-left: 10px;
    margin-top: -6px;
    left: 0;
	border-color: #61e1b9;
	border: 3px solid #f5c745;
}
.hongse {
    box-sizing: border-box;
    content: '';
    width: 12px;
    height: 12px;
    border-radius: 50%;
    position: absolute;
    top: 50%;
    margin-left: 10px;
    margin-top: -6px;
    left: 0;
    border-color: #61e1b9;
    border: 3px solid #f1787f;
}
/***二级导航前面小圆点结束***/

3、导航前面添加小圆点，在后台-菜单里设置，如下图：

<i class="hongse"></i> //这里的"hongse"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
