我一直在为客户端开发Web应用程序,并在构建数据库登录代码时遇到此错误。
config.php代码
php try {
// Create connection
$dbh = new PDO("mysql:host=" . $localhost . ";dbname=" . $database, $username, $dbpassword);
} catch (PDOException $e) {
// Echo error message if the connection fails
echo 'Connection failed: ' . $e->getMessage();
exit;
}
login.php代码
require 'config.php';
$sql = "SELECT * FROM `Users` WHERE `email` = ?";
$stmt = $dbh->prepare($sql);
$result = $stmt->execute([$_POST['email']]);
$users = $result->fetchAll();
if (isset($users[0])) {
if (password_verify($_POST['password'], $users[0]->password)) {
// valid login
include 'dashboard.php';
}
else {
// invalid password
echo "<p class=''>The password you entered is Incorrect. Please try again.</p>";
}
}
else {
// invalid email
echo "<p class=''>We're sorry, That email is not in our Records. Please Check the spelling and try again.</p>";
}
Register.php有效,并将字段添加到数据库中,但我会添加以确保我没有遗漏任何内容,因为它正在尝试访问数据库以验证记录。
require 'config.php';
require 'lib/password.php';
$company = $_POST["company"];
$email = $_POST["email"];
$password = $_POST["password"];
$hash = password_hash($password, PASSWORD_BCRYPT);
$stmt = $dbh->prepare("insert into Users(id,company,email,password) VALUES (?,?,?,?)");
$stmt->execute([$id, $company, $email, $hash]);
答案 0 :(得分:-1)
您使用了错误的对象($ result)来获取
您需要使用$ stmt 这样做
$users = $stmt->fetchAll();
另外,您需要在此之前将变量作为数组传递
$stmt->execute(array($_POST['email']));
