注意未定义的偏移量：2

问题描述

我正在使用 PHP 代码将来自 TMDB 的数据保存在 wordpress MetaBox 字段上，每次我创建新文章时，日志都会给我很多错误：

PHP Notice Undefined index: sp_nonce_name in C:\xampp\htdocs\clean\wp-content\themes\moviewp\lib\MetaBox.PHP on line 176
PHP Notice Undefined offset: 2 in C:\xampp\htdocs\clean\wp-content\themes\moviewp\lib\MetaBox.PHP on line 71

这是我使用的代码：

        array( '720p','720p'),array( '1080p','1080p'),array( 'download','Download'),array( 'player_desc','player_desc','playerdescription' ),);

如果我在第 71 行和第 176 行之前输入这个错误就会消失

第 71 行

if ( ! isset($args[2])) {
   $args[2] = null;
}

第 176 行

if(!empty($_POST[$sp_fields[0]]))
if($_POST[$sp_fields[0]]!="")

但是如果我尝试更新该字段并保存帖子，该字段不会更新
