【问题描述】：
我在这里的第一篇文章，尽管我是这个非常有用的网站的常客
我想知道是否有人可以帮助我解决以下问题：
我正在用 PHP 和 MySQL 为我的公司编写一个简单的库存检查解决方案，我还是个新手，但正在学习。
我们有以下搜索表单，当输入产品的条形码时，它会显示来自数据库的结果，我想做的是在结果底部有一个按钮，上面写着“Checked OK”，它会重新提交信息返回数据库，更新时间戳，并有一个隐藏字段将“状态”更改为已检查。
数据库名称是“股票” 表名是“main_stock” 这些字段是： ID 当前时间戳 主类 类别 产品描述 条码 串行 状态
每个搜索只给出一个结果，因为条形码是唯一的
我坚持的一点是如何将结果转换为表单，以便能够将它们重新提交回数据库
这仅供受保护网络内部使用，非常感谢任何帮助
谢谢
乔恩
