您好我一直在寻找解决此问题的周。我有一个登录代码，在输入您的信息后，登录表单将信息发送到php页面，该页面运行包含的函数，包括检查数据库并保存信息（如果匹配），然后返回true。 php页面然后重定向到运行登录检查功能的主页，但会话不存在。
我已经确定我有session_start（）;在所有页面的顶部 标题有一个exit（）;在它之后，重定向是标题（'Location：../ home.php'）; 我检查了phpinfo（）; 我试过session_write_close（）;和session_regenerate_id（true）;, session_regenerate_id（）; iv选中Session save path / temp
会话保存所有内容，直到重定向iv回显到每个帮助网站和页面
这是登录
if (login($email, $password, $mysqli) == true) {
// Login success
session_write_close();
header('Location: ../home.php');
exit();
} else {
// Login failed
header('Location: ../signIn.php?error=1');
exit();
}
我在登录功能中保存会话，当我在这里回复它们时它们仍然存在但是在重定向之后我在loginCheck函数中回显并且没有任何内容。
这是使用
的会话功能function sec_session_start() {
$session_name = 'sec_session_id';
$secure = 'SECURE';
$httponly = true;
if (ini_set('session.use_only_cookies', 1) === FALSE) {
header("Location: ../error.php?err=Could not initiate a safe session (ini_set)");
exit();
}
$cookieParams = session_get_cookie_params();
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
session_name($session_name);
session_start();
session_regenerate_id();
}
这是我的loginCheck剂量使它通过第一个如果没有会话
function login_check($mysqli) {
// Check if all session variables are set
echo $_SESSION['hello'];
echo $_SESSION['username'];
echo $_SESSION['user_id'];
echo $_SESSION['login_string'];
echo 'hello';
if (isset($_SESSION['user_id'], $_SESSION['username'], $_SESSION['login_string'])) {
//if ($_SESSION['Logging'] == "correct") {
echo 'hello';
$user_id = $_SESSION['user_id'];
$login_string = $_SESSION['login_string'];
$username = $_SESSION['username'];
// Get the user-agent string of the user.
$user_browser = $_SERVER['HTTP_USER_AGENT'];
if ($stmt = $mysqli->prepare("SELECT password
FROM company_users
WHERE id = ? LIMIT 1")) {
// Bind "$user_id" to parameter.
$stmt->bind_param('i', $user_id);
$stmt->execute(); // Execute the prepared query.
$stmt->store_result();
if ($stmt->num_rows == 1) {
// If the user exists get variables from result.
$stmt->bind_result($password);
$stmt->fetch();
$login_check = hash('sha512', $password . $user_browser);
if ($login_check == $login_string) {
// Logged In!!!!
return true;
} else {
// Not logged in
return false;
}
} else {
// Not logged in
return false;
}
} else {
// Not logged in
return false;
}
} else {
// Not logged in
return false;
}
}
这是表格
<form class="form-horizontal" action="includes/signInValidation.php" method="POST" name='login_form'>
<div class="form-group">
<label class="col-lg-2 control-label ">Email</label>
<div class="col-lg-10">
<input class="form-control textBox" id="email" name='email' placeholder="Email" type="email">
</div>
</div>
<div class="form-group">
<label class="col-lg-2 control-label ">Password</label>
<div class="col-lg-10">
<input class="form-control textBox" id="password" nam='password' placeholder="Password" type="password">
</div>
</div>
<div class="form-group">
<label class="col-lg-2 control-label "></label>
<div class="col-lg-10">
<input class="btn btn-success" type="button" value='Login' onclick='formhash(this.form, this.form.password);' >
</div>
</div>
</form>
这是登录功能

// Using prepared statements means that SQL injection is not possible.
if ($stmt = $mysqli->prepare("SELECT id, username, password, salt

$stmt->fetch();
// hash the password with the unique salt.
$password = hash('sha512', $password . $salt);
if ($stmt->num_rows == 1) {
// If the user exists we check if the account is locked
// from too many login attempts
if (checkbrute($user_id, $mysqli) == true) {
// Account is locked
// Send an email to user saying their account is locked
return false;
} else {
// Check if the password in the database matches

// Get the user-agent string of the user.
$user_browser = $_SERVER['HTTP_USER_AGENT'];

} else {
// Password is not correct
// We record this attempt in the database
$now = time();

VALUES ('$user_id', '$now')");

我自己有这个问题。最终解决方案是我没有使用带有Location：标头的绝对URI 。
这样做而不是'../home.php'：
header('Location: http://yourdomain.com/home.php');

使代码尽可能简单。没有必要回应确认会话设置。您需要一起重新设计流程
<?php
session_start();
if ( !isset( $_SESSION['user_id'] ) )
{ header("location:index");
}
