php 注册不推送到数据库问题

Question

我有 2 个类 - db.class.php 和 user.class.php。在第二个中，我有两种与注册相关的方法 - register 和 registerValidation。 db 文件负责指定数据库凭据和初始化连接。我真的不想污染我的 post 所以我只会给你数据库代码作为 link 因为我真的不认为问题出在那里。

register方法和validation方法的代码为：

<?php

require_once 'token.php';

class User
{
    //db and table name
    private $conn;
    private $table_name = "users";

    // constructor with $db as database connection
    public function __construct($db)
    {
        $this->conn = $db;
    }

    public function registerValidation($nick,$email,$password)
    {
        if(
            (strlen($nick) < 5 || strlen($nick) > 20) ||
            (strlen($email) < 3 || strlen($email) > 100) ||
            (strlen($password) < 6 || strlen($password) > 50)
        )
        {
            //$error = 'nick or email or password is wrong length';
            //echo json_encode($error);
            return false;
        }
        else
        {
            // query to check if email already exists
            $query = "
                SELECT 
                  * 
                FROM 
                  " . $this->table_name . " 
                WHERE 
                  id = ?
                  OR
                  email = ?
              ";

            // prepare query statement
            $stmt = $this->conn->prepare($query);

            // bind params
            $stmt->bindParam(1, $nick);
            $stmt->bindParam(2, $email);

            // execute query
            $stmt->execute();

            //count if there is same
            $num = $stmt->rowCount();

            if ($num > 0)
            {
                return false;
            }
            else
            {
                return true;
            }
        }
    }

    public function register($nick,$email,$password)
    {
        try
        {
            $password = password_hash($password, PASSWORD_DEFAULT);

            $query = "
                INSERT INTO
                  users(user, user, user) 
                VALUES
                  (?, ?, ?)";

            // prepare query statement
            $stmt = $this->conn->prepare($query);

            //bind values from user
            $stmt->bindparam(1, $nick);
            $stmt->bindparam(2, $email);
            $stmt->bindparam(3, $password);

            $stmt->execute();

            return $stmt;
        }
        catch(PDOException $e)
        {
            echo $e->getMessage();
        }
    }

我还有文件 doRegister.php，它是客户端的某种端点：

<?php

if(isset($_POST['submit']))
{
    if(!empty($_POST['nick'])
        && !empty($_POST['email'])
        && !empty($_POST['password']))
    {
        // instantiate database
        require_once '../config/database.php';
        $database = new Database();
        $db = $database->getConnection();

        require_once '../classes/user.php';
        $user = new User($db);

        if($user->registerValidation($_POST['nick'], $_POST['email'], $_POST['password']))
        {
            $user->register($_POST['nick'], $_POST['email'], $_POST['password']);
            http_response_code(201);
        }
        else
        {
            http_response_code(400);
        }
    }
    else
    {
        http_response_code(400);
    }
}
else
{
    http_response_code(400);
}

当我通过 postman 发送 http POST 请求时，我得到 201(created) 但是当我之后转到 localhost/phpmyadmin 时，用户 table 在我的 mysql 数据库中。为什么？

Answer 1

register 函数在执行 insert 语句时肯定会返回 false。而且看起来这些列是错误的。

        $query = "
            INSERT INTO
              users(nick, email , password) 
            VALUES
              (?, ?, ?)";

#before returning true or false do a check on execute()
return $stmt->execute() === true ?  true  : false;

同样在返回 header 201 之前，检查 register 函数以验证它是真的而不是假的..
