【问题描述】：
我使用以下website 的代码为我的网站提供添加用户功能。我以前用过，效果很好。但是现在我已经改变了它并根据我的需要进行了修改。但是它似乎不起作用。我收到的错误消息是“请正确输入表格”，这是我在未发送各个字段时设置的消息（请参阅下面粘贴的代码）。我想这可能是我搞砸了，所以我尝试了网站的代码，但它不起作用。是wamp服务器设置的原因吗？还是cz
- 我正在检查是否只有用户名和密码以及会话表单令牌？
- 仅检查上述字段后，我将向数据库中添加更多信息 - 姓名、电子邮件 ID 等
- 我的数据库表的列数超过了我传递的值的数量。
由于我是 php 授权和验证的新手，所以我想不出任何可以调试的东西。任何帮助都将非常感激。我在下面发布我的 html 表单和 php 代码。我的 sql 表看起来有以下列：用户 ID、名字、姓氏、用户名、密码、电子邮件 ID、团队名称、金钱、总数、积分
html 表单 -

session_start();

$form_token = md5( uniqid('auth', true) );

【问题讨论】：
-
您确定收到“请正确输入表单”错误吗？我无法在您的代码中找到它。
-
@Babblo 很抱歉，我出于挫败感改成了“为上帝的爱工作”。它是我存储在
$message变量中的第一个字符串 -
所以它正在工作。有什么问题？
-
这是我在未发送表单详细信息时应该收到的消息。我想不出为什么会这样。检查
useradd.php代码最开始处的if isset语句 -
哎呀，对不起..我没看到！符号
