php - 未定义索引 PHP

Question

我一直在尝试获取 HTML/PHP 中的表单以处理到 numyspace 服务器上的 mysql/phpmyadmin 表中，但由于我自己不知道的原因，我收到以下错误消息。

Notice: Undefined index: Username in /var/www/vhosts/numyspace.co.uk/web_users/home/~unn_w11034582/public_html/CaseProject/registerUserProcess.php on line 14

正如它所说的插入用户 () 用户是我在数据库中的表，我希望将信息插入其中。 (所有拼写和大写都在正确的位置)我不确定为什么所有的值都是空白的，因为看起来它没有从提供的单元格中收集信息。

任何帮助提示或指示都将非常适用，谢谢大家 DateOfCreation 是 atm 的问题，也许应该将其删除，因为它试图将“我接受条款和条件”复选框转换为时间戳以存储用户最初创建帐户的日期。代码处于早期阶段，不包含任何验证，因此可以在需要时提供代码，只需用谷歌搜索错误消息，似乎此错误消息有很多不同的类型。

RegisterUserProcess.php
<?php
    include ("connection.inc.php");
    connect();

        $username = $_POST['Username'];
        $firstName = $_POST['Forename'];
        $lastName = $_POST['Surname'];
        $address = $_POST['Address'];
        $postCode = $_POST['PostCode'];
        $emailAddress = $_POST['EmailAddress'];
        $password = $_POST['Password'];
        $termsConditions = $_POST['DateOfCreation'];

            $sql="INSERT INTO User (Username, Forename, Surname, Address, PostCode, EmailAddress, Password, DateOfCreation)
            VALUES ('$username', '$firstName', '$lastName', '$address', '$postCode', '$emailAddress', '$password', '$termsConditions')";

                mysql_query($sql);
                print("Thank You " +$firstName+" "+$lastName + " You Have Successfully Created An Account!");
                echo $sql;

?>

您应该添加下面列出的这些更改

Note: $_POST['someelement'] is case-sensitive.

注册用户进程.php

<?php
include ("connection.inc.php");
connect();
    $username = $_POST['username'];
    $firstName = $_POST['firstname'];
    $lastName = $_POST['lastname'];
    $address = $_POST['address'];
    $postCode = $_POST['postCode'];
    $emailAddress = $_POST['emailAddress'];
    $password = $_POST['password'];

而且您从未在 html 表单中指定输入名称 dateofcreation。如果您想要时间戳，您应该将 dateofcreation 字段更改为时间戳并在查询中使用 now()

    $termsConditions = $_POST['dateOfCreation'];

        $sql="INSERT INTO User (Username, Forename, Surname, Address, PostCode, EmailAddress, Password, DateOfCreation)
        VALUES ('$username', '$firstName', '$lastName', '$address', '$postCode', '$emailAddress', '$password', 'now()')";

            mysql_query($sql);
            echo "Thank You $firstName $lastName You Have Successfully Created An Account!";
            echo $sql;

?>

并且您的代码需要大量更改。这是一个建议。如果您在同一个脚本中执行代码，那么您应该使用 isset

eg: if(isset($_REQUEST['submit']) { some code... } else { html form... }
