Question

我试图将数据从注册表单插入到数据库中，但是当我点击注册时，我在数据库中看不到任何内容。

我真的需要解决这个问题，以便我能够插入到我的数据库中。我无法确定问题的来源。非常感谢您的贡献。

这是我的代码帮助我。请帮帮我。

    <?php

    session_start();

    $server = 'localhost';
    $users = 'root';
    $pass = '';
    $dataBase = 'accounts';

    $_SESSION['message'] = '';

    $mysqli = new mysqli($server, $users, $pass, $dataBase) or die("Not connected");

    if($mysqli){

        echo 'Connected Successfully';
    }

    if ($_SERVER['REQUEST_METHOD'] == 'POST'){


        //The two passwords are equal to each other
        if($_POST['Password'] == $_POST['ConfirmPassword']){

            $username = $mysqli->real_escape_string($_POST["username"]);
            $email = $mysqli->real_escape_string($_POST['email']);
            $password = md5($_POST['Password']); //hash password security
            $phone = $mysqli->real_escape_string($_POST['Number']);


            $_SESSION['username'] = $username;

            $sql = "INSERT INTO user (username, email, password, phone) VALUES ('$username','$email','$password','$phone')";

            //if the query is correct, then redirect to a welcome.php page. done!
            if($mysqli->query($sql) === true){

               $_SESSION['message'] = "Registration successful! $username is now a member";
               header("location: login.php");

                echo 'Successfully Registered!';

            }
            else{
                $_SESSION['message'] == "Sorry you are not registered, check your field";

                }

            }

            else{
                $_SESSION['message'] == "Passwords do not match!";
            }
        }
 ?>

Answer 1

将名称提交给提交按钮并使用

if (isset($_POST['submit'])){
}

insted of

if ($_SERVER['REQUEST_METHOD'] == 'POST'){
}

Answer 2

可能是您的SQL查询出错，只需回显$sql并将输出运行到phpmyadmin。

示例：

$sql = "INSERT INTO user (username, email, password, phone)     VALUES ('$username','$email','$password','$phone')";
echo $sql;
exit();

然后将输出运行到phpmyadmin。

Answer 3

您还可以在行动中加入php_self：

<?php echo $_SERVER['PHP_SELF']; ?>

并使您的SQL查询更改

$sql = "INSERT INTO user (username, email, password, phone) VALUES ('".$username."','".$email."','".$password."','".$phone."')";

希望这有帮助!!!

Answer 4

你的变量被视为字符串，所以试试这个：

$sql = "INSERT INTO user (username, email, password, phone)     VALUES ('".$username."','".$email."','".$password."','".$phone."')";

连接并插入php数据库
