我的登录名如下:
<form action="authenticate.php" method="post">
<label for="username">
<i class="fas fa-user"></i>
</label>
<input type="text" name="username" placeholder="Username" id="username" required>
<label for="password">
<i class="fas fa-lock"></i>
</label>
<input type="password" name="password" placeholder="Password" id="password" required>
<input type="submit" value="Login">
</form>
下面是我的authenticate.php
<?php
session_start();
include('config.php');
if ( mysqli_connect_errno() ) {
die ('Failed to connect to MySQL: ' . mysqli_connect_error());
}
if ( !isset($_POST['username'], $_POST['password']) ) {
die ('Please fill both the username and password field!');
}
if ($stmt = $link->prepare('SELECT id, password FROM accounts WHERE username = ?')) {
$stmt->bind_param('s', $_POST['username']);
$stmt->execute();
$stmt->store_result();
if ($stmt->num_rows > 0) {
$stmt->bind_result($id, $password);
$stmt->fetch();
if (password_verify($_POST['password'], $password)) {
$_SESSION['loggedin'] = TRUE;
$_SESSION['name'] = $_POST['username'];
$_SESSION['id'] = $id;
header('Location: index.php');
exit();
} else {
echo 'Incorrect password!';
}
} else {
echo 'Incorrect username!';
}
$stmt->close();
}
我在每个标头上都使用了以下php代码,以便在未登录的情况下重定向用户
<?php
// We need to use sessions, so you should always start sessions using the below code.
session_start();
include('config.php');
// If the user is not logged in redirect to the login page...
if (!isset($_SESSION['loggedin'])) {
header('Location: login.php');
exit();
}
?>
一切都在我的本地主机上正常运行,现在我将其上传到服务器上,即使我登录后,问题仍然存在,我再次重定向到登录页面。这是我的网站供参考: enter link description here 谁能告诉我我的代码可能是什么问题?

我已经找到了问题所在,以后如果有人遇到同样的错误,希望对您有帮助
域指向.html网站,因此php.ini文件不存在,现在已添加并可以正常工作

在分配会话之前使用session_start()
if (password_verify($_POST['password'], $password)) {
session_start();
$_SESSION['loggedin'] = TRUE;
$_SESSION['name'] = $_POST['username'];
$_SESSION['id'] = $id;
header('Location: index.php');
exit();
