Question

在我的注册页面上，它会询问电子邮件和密码，然后将其插入数据库。然后，用户被转发到注册页面，其形式为insertregstration.php =见下文。

问题 - 然后插入所有内容，然后删除电子邮件和密码。我遇到了麻烦，似乎这个代码就是问题所在。

请帮助。

<?php

    session_start();
        $con=mysqli_connect("localhost", "root", "", "info");
        if (mysqli_connect_errno()) {
             echo "Failed to connect to MySQL: " . mysqli_connect_error();
        }

        $firstname = mysqli_real_escape_string($con, $_POST['firstname']);
        $lastname = mysqli_real_escape_string($con, $_POST['lastname']);
        $gender = mysqli_real_escape_string($con, $_POST['gender']);
        $contact = mysqli_real_escape_string($con, $_POST['contact']);
        $email = mysqli_real_escape_string($con, $_POST['email']);
        $password = mysqli_real_escape_string($con, $_POST['password']);
        $addressone = mysqli_real_escape_string($con, $_POST['addressone']);
        $addresstwo = mysqli_real_escape_string($con, $_POST['addresstwo']);
        $city = mysqli_real_escape_string($con, $_POST['city']);
        $state = mysqli_real_escape_string($con, $_POST['state']); 
        $zip = mysqli_real_escape_string($con, $_POST['zip']); 

    $sql="UPDATE users SET firstname='$firstname', lastname = '$lastname', gender = '$gender', contact='$contact', email = '$email', password = '$password', addressone='$addressone', addresstwo= '$addresstwo',`city`='$city', state = '$state', zip = '$zip' WHERE id='" .$_SESSION['id']."'";

        if (!mysqli_query($con,$sql)) {
          die('Error: ' . mysqli_error($con));
        }
        header("Location:dashboard.php");
        mysqli_close($con);
?>

这是注册页面吗？注册意味着添加新用户。使用插入查询，可能是电子邮件和密码var返回一个空字符串值，因此它会自动将空字符串更新到数据库表。

插入时删除数据
