我目前正在为我的应用注册，直到我遇到这个问题，每当我进入我的页面时，它会在我的users表中创建一个新行。似乎当我重新加载页面时，表单会自动提交。我曾提到this问题：
使用标题（“location：”）;插入完成后，将显示一个新的表单，刷新不会导致再次提交。
然而，当我这样做时发生的一切都是一个很大的重定向循环，阻止我一起访问该页面。
以下是我的注册代码：
<?php
global $conn;
global $register;
global $error;
$username = $_POST['username'];
$firstName = $_POST['firstName'];
$lastName = $_POST['lastName'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$password = $_POST['password'];
$confirmPassword = $_POST['confirmPassword'];
define(HEADER_TITLE, "Register");
include_once 'template/header.php';
if (isset($_POST['register'])) {
$register->register($username, $firstName, $lastName, $email, $phone, $password, $confirmPassword);
}
?>
<div class="container">
<div id="hoogley_login">
<h2>Register</h2><hr>
<div class="alert alert-danger" role="alert">
<?php
if ($error->display() != null ) {
#echo '<div class="alert alert-danger" role="alert">';
$error->display();
} else {
#echo '<div>';
}
?>
</div>
<form action="register" method="post">
<input type="text" class="form-control" name="firstName" placeholder="First Name" value="<?php echo $_GET['firstName']; ?>">
<br>
<input type="text" class="form-control" name="lastName" placeholder="Last Name" value="<?php echo $_GET['lastName']; ?>">
<br>
<input type="text" class="form-control" name="username" placeholder="Username" value="<?php echo $_GET['username']; ?>">
<br>
<input type="email" class="form-control" name="email" placeholder="E-Mail Address" value="<?php echo $_GET['email']; ?>">
<br>
<input type="tel" class="form-control" name="phone" placeholder="Phone Number" value="<?php echo $_GET['phone']; ?>">
<br>
<input type="password" class="form-control" name="password" placeholder="Password">

<a href="/login">Have an account? Login!</a>
</form>
</div>
</div>
<?php include_once 'template/footer.php'; ?>
我的register.class.php：

谢谢！

这是因为您的方法与类名具有相同的名称。它作为PHP 4构造函数工作，它在初始化对象时调用该方法。
