我已经尝试调试这个问题将近 4 个小时，但没有成功。没有错误消息，$stmt -> execute() 出于我不知道的任何原因给出 false。
注册.php
<?php
session_start();
if( isset($_SESSION['id'])){
header("Location: index.php");
}
require 'database.php';
$message = '';
if(!empty($_POST['user']) && !empty($_POST['password'])):
$pass = $_POST['password'];
$user = $_POST['user'];
$sql = "Insert into user (username, password) values (:user, :password)";
$stmt = $conn->prepare($sql);
$stmt->bindValue(':user', $_POST['user']);
$stmt->bindValue(':password', password_hash($_POST['password'], PASSWORD_BCRYPT));
//var_dump($_POST['password']);
//var_dump($_POST['user']);
if($stmt -> execute()):
$message = 'Successfully created new user';
else:
$message = 'Sorry there must have been an issue creating your account';
endif;
endif;
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Register Below</title>
</head>
<body>
<?php if(!empty($message)): ?>
<p><?= $message ?></p>
<?php endif; ?>
<h1>Register</h1>
<form class="" action="register.php" method="post">
<input type="text" placeholder="Username" name="user" id="user">
<input type="password" placeholder="and password" name="password" id="password">
<input type="password" placeholder="confirm password" name="confirm_password">
<button type="submit" name="button">Register</button>
</form>
<a href="./index.php">home</a>
</body>
</html>
数据库.php
<?php
$server = 'localhost';
$username ='master';
$password ='master';
$database = 'quiz';
try{
$conn = new PDO("mysql:host=$server;dbname=$database;" , $username, $password);
} catch(PDOException $e){
die ("Connection failed" . $e->getMessage());
}
?>
我知道我忽略了确认密码，但我想确保我可以先插入数据库。
最佳答案
解决方案:我的数据库中的密码长度为 15...散列密码 >> 15 个字符。将长度更改为 255，一切都很好。希望这对其他人有用。
