我有一个PHP文件User.php，其中包含一个类User，一些私有全局变量，getter和setter，一个构造函数以及一个连接到数据库的方法。
<?php
class User {
//Some Private Global Variables ($firstName,$lastName,etc..)
//Getters and Setters
public function getUserByID($userID) {
//Create Instance
$user = new User();
//Get User Info
$con=mysqli_connect("localhost","root","","mydatabase");
if ($con->connect_error) {
die('Connect Error: ' . $con->connect_error);
}
$query ='SELECT user_id,first_name,last_name,email,password,birth_date,gender,join_date '.
'FROM users '.
'WHERE user_id = ?';
$stmt = $con->stmt_init();
if($stmt->prepare($query)) {
$stmt->bind_param('s',$userID);
$stmt->execute();
$stmt->bind_result($user->userID,$user->firstName,$user->lastName,$user->email,$user->password,$user->birthDate,$user->gender,$user->joinDate);
if($stmt->fetch()==null) {
//User doesn't exist
return null;
}
$stmt->close();
$con->close();
return $user;
}
}
?>
在另一个包含表单的文件中，如果我在if( isset($_POST['submit']) )之前执行以下操作：
$user = new User();
$user1 = $user->getUserByID('222');
一切都很完美，但如果它写在它之后，我填写表格并发布，它就不会执行，我会收到：

答案 0 :(得分：0)
您的while ($exists)循环代码似乎有误。如果$exists = false，您应该设置$user == null，而您正在做相反的事情。另外，为什么要生成ID，然后再次查看具有给定电子邮件地址的用户？你不应该找一个具有相同ID的用户吗？
