我正在开发一个网页，在其中显示有关绘画的信息。

我创建了一个名为“register.php”的网页，用户在订购绘画之前必须填写注册表。然后出现一个名为“details.php”的页面，要求用户输入更多详细信息。最后会显示一个名为“vieworders.php”的页面，显示订单的详细信息和绘画的状态。

问题1:我创建了一个名为“users”的数据库，其中包含以下字段“id(主键自增)，用户名，电子邮件和密码。为什么当用户提交注册表单时，数据没有显示在我的数据库？？

问题2:用户如何能够随时返回并检查绘画的状态？

这是我的代码:

注册.php

<?php
session_start();

$id = $_POST["accept"];
$paintingname = $_POST["accept1"];

$host = "xx";
$user = "xx";
$pass= "xx";
$dbname = "xx";
$conn = new mysqli($host,$user,$pass, $dbname );

$_SESSION['id'] = $id;
$_SESSION['paintingname'] = $paintingname;

if ($conn->connect_error) {
    die("Connection failed : ".$conn->connect_error); //fixme
}

    if (isset($_POST['reg_user'])) {

        $username = isset($_POST["username"]) ? $conn->real_escape_string($_POST["username"]) : "";
        $email = isset($_POST["email"]) ? $conn->real_escape_string($_POST["email"]) : "";
        $password = isset($_POST["password"]) ? $conn->real_escape_string($_POST["password"]) : "";
        $password2 = isset($_POST["password2"]) ? $conn->real_escape_string($_POST["password2"]) : "";


        if ($password_1 != $password_2) {
            array_push($errors, "The two passwords do not match");
        }

        // first check the database to make sure
        // a user does not already exist with the same username and/or email
        $user_check_query = "SELECT * FROM users WHERE username='$username' OR email='$email' LIMIT 1";
        $result = mysqli_query($conn, $user_check_query);
        $user1 = mysqli_fetch_assoc($result);

        if ($user1) { // if user exists
            if ($user1['username'] === $username) {
                array_push($errors, "Username already exists");
            }

            if ($user1['email'] === $email) {
                array_push($errors, "email already exists");
            }
        }

        // Finally, register user if there are no errors in the form
        if (count($errors) == 0) {
            $password = md5($password_1);//encrypt the password before saving in the database

            $query = "INSERT INTO users(username, email, password) 
                VALUES('$username', '$email', '$password')";
            mysqli_query($db, $query);

        }
    }

最佳答案

您将注册表单发布到 confirm.php，因此 register.php 中的代码永远不会执行
