PHP SQL将文本值插入数据库

标签： php mysql

我正在开发一个在线购物车项目，这要求我能够为添加到购物车的每个项目添加自定义文本输入字段。但是，当我尝试将卡中每个项目的信息插入数据库时​​，我无法弄清楚如何将itemtext值传递给我的INSERT语句。我如何能够将itemtext值从初始项目列表传递到Orderitems的数据库中？ itemtext输入在第170行，我想将它传递给第83行看到的INSERT语句。

1 个答案:

答案 0 :(得分：0)

更新：这是您的答案：将'$itemtext[itemnumber]'更改为'$itemtext'

由于您使用引号的方式，这是错误的。（不是答案，但您可能要考虑它;-)）

$sql = "INSERT INTO Orders (email, orderdate, ordercost, ordertype, downcost, cardtype, cardnumber, cardsec, cardexpdate, orderstatus)
        VALUES ('$email', '$orderdate', '$ordercost', '$ordertype', '$downcost', '$cardtype', '$cardnumber', '$cardsec', '$cardexpdate', '$orderstatus')";

你不使用'$email'但是 - 例如 - ...VALUES ('".$email."',...

点击此处了解详情：What is the difference between single-quoted and double-quoted strings in PHP?

另一方面，您的代码不安全。请使用：http://php.net/manual/en/function.mysql-real-escape-string.php

例：
...VALUES ('".mysql_real_escape_string($email)."',...
