我知道有一些与此相关的问题,但有c ++或其他语言.我收到此错误,我不确定我的功能有什么问题.
我的错误看起来像这样:
Fatal error: Uncaught ArgumentCountError: Too few arguments to function User::register(), 2 passed in C:\xampp\htdocs\register.php on line 39 and exactly 5 expected in C:\xampp\htdocs\classes\users.php:22 Stack trace: #0 C:\xampp\htdocs\register.php(39): User->register('ds', 'dsssssss') #1 {main} thrown in C:\xampp\htdocs\classes\users.php on line 22
我的功能是:
public function register($name, $surname, $username, $password, $email)
{
try {
$newPassword = password_hash($password, PASSWORD_DEFAULT);
$stmt = $this->conn->prepare("INSERT INTO user(name, surname, username, password, email)
VALUES(:name, :surname, :username, :password, :email)");
$stmt->bindParam(":name", $name);
$stmt->bindParam(":surname", $surname);
$stmt->bindParam(":username", $username);
$stmt->bindParam(":password", $password);
$stmt->bindParam(":password", $password);
$stmt->bindParam(":email", $email);
$stmt->execute();
return $stmt;
}
catch(PDOException $e) {
echo $e->getMessage();
}
}

在PHP 7而不是:
public function register($name, $surname, $username, $password, $email)
{
...
使用:
public function register($name = null, $surname = null, $username = null, $password = null, $email = null)
{
...
您的方法需要 5 个参数，您只需传递 2 个： User->register('ds', 'dsssssss')
编辑此行Register.php：
$user->register($username, $password)
到
$user->register($name, $surname, $username, $password, $email)
另外你有这行两次 $stmt->bindParam(":password", $password);
