无法插入数据库

标签： php mysql

我的问题是，当我提交表单时，我无法在下面的代码中将变量$ skyr，$ eftir，$ notandi，$ pass和$ mel插入到我的Mysql数据库中。 Insert语句是正确的，$ conn变量中的mysqli_connect（）是正确的，我用其他文件中的其他变量测试它。那么，我的代码中的问题是什么？我做错了什么？

这是我的代码：

UPTADE： 我发现insert语句不起作用。 我确信连接正常，它已在其他文件中使用，并在正常工作时使用。然后出了点问题。我不知道为什么。

那么，下面这段代码有什么问题？

$skyr = "Arnar";
$eftir = "Kristinsson";
$notandi = "afk0901";
$pass = "afk0901"; 
$mel = "arnarfreyr@hive.is";
    $data = "INSERT INTO Login(Skírnarnafn,Eftirnafn,Notandanafn,Lykilorð,Tölvupóstur) 
    VALUES ('$skyr', '$eftir', '$notandi', '$pass', '$mel')";
    mysqli_query($conn,$data);
    mysqli_close($conn);

1 个答案:

答案 0 :(得分：0)

看起来我发现了什么问题......这不是我的代码。这是数据库。我使用了错误的索引。我将索引类型从唯一更改为索引。问题解决了。谢谢谁试图回答:)我真的在5天后发现了这个...我不知道为什么我之前没有记住这一点。
