状态更改按钮单击php mysql PDO

我正在尝试更改MySQL表中接收到的包状态，我猜操作执行得不好，请有人发现错误，我正在粘贴下面的代码

当我将操作代码放入while循环时，它会将所有记录的状态更改为Received。但是当我把它放在while循环之外时，什么也没有发生

这不应该从
1
开始复制吗<代码>$q->bindColumn（2$custemail）
@Fred ii-最有可能的列
1
是行
id
，OP不想检索/返回该行。我的印象是PDO需要遵循@SeanNo序列，而不是字段。它们是否都具有相同的值->
id=1客户电子邮件=name@email.com，id=2客户电子邮件=name@email.com等。
如果每个记录的
cust_email
值相同，则需要在更新中使用
id
或其他唯一值。
