【问题描述】：
我现在搜索了几个小时，但找不到任何解决方案。我希望你能帮助我。
我创建了一个网站并使用 xampp 对其进行了测试，并且eververthing 运行良好，但现在我将其上传到服务器上，我发现session_start() 不起作用。
这是我的 index.php 的代码：
<?php
session_start();
echo session_status()."<br>";
echo "SessionID: ".session_id();
error_reporting(E_ALL & ~E_NOTICE);
?>
<html>
<head>
<link rel="stylesheet" type="text/css" href="stylesheet.css" media="screen" />
<meta charset="UTF-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
$(".loginField").click(function() {
$(".loginDetails").toggle("slow");
});
$(".profilName").click(function() {
$(".profilMenu").toggle("slow");
});
$("#middleLoginButton").click(function() {
$(".middleLoginForm").toggle("slow");
});
});
</script>
</head>
<body>
<!-- getting UserData, if available -->
<?php
//delete Session Data, if logout
if (isset($_GET['logout']) && $_GET['logout'] == 1) {
echo "SessionID Logout:".session_id();
session_destroy();
//header("Location:https://www.whocando.eu");
}
function autoload ($className) {
if (file_exists('classes/'.$className.'.php')) {
require 'classes/'.$className.'.php';
}
}
spl_autoload_register("autoload");
if ($_GET['falsePassword'] == 1) {
$falsePassword = 1;
}
if ((empty($_POST['userName']) || empty($_POST['password'])) && empty($_POST['registration'])) {
// after Login Check!
} elseif (isset($_POST['userName']) && isset($_POST['password']) && !isset($_POST['registration'])) {
$loginCheck = new loginParser();
$userID = $loginCheck->loginChecker($_POST['userName'],$_POST['password']);
$_SESSION['userID'] = $userID;
$abfrage = new dbQuery("SELECT ID,name, firstName FROM db764570417.userdata WHERE ID = $userID");
$userName = $abfrage->fetchData('ID','name');
$userFirstName = $abfrage->fetchData('ID','firstName');
// already logged in Check!
} elseif (isset($_SESSION['userID'])) {
$userID = $_SESSION['userID'];
$abfrage = new dbQuery("SELECT ID,name, firstName FROM db764570417.userdata WHERE ID = $userID");
$userName = $abfrage->fetchData('ID','name');
$userFirstName = $abfrage->fetchData('ID','firstName');
// after Registration Check!
} elseif (isset($_POST['registration'])) {
$name = $_POST['name'];
$vorName = $_POST['vorname'];
$email = $_POST['email'];
$uni = $_POST['uni'];
$geburtstag = $_POST['gebDatum'];
$password = $_POST['passwort'];
$confirmedPassword = $_POST['confirmPasswort'];
$gebDatum = date("Y-m-d",strtotime($geburtstag));
$abfrageEmail = new dbQuery("SELECT ID,email FROM db764570417.logindata");
$userEmails = $abfrageEmail->fetchData('ID','email');
if ($password != $confirmedPassword) {
header("Location:https://www.whocando.eu/registration.php?fault=passwordNotMatched&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (in_array($email,$userEmails)) {
header("Location:https://www.whocando.eu/registration.php?fault=emailAlreadyUses&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (empty($name)) {
header("Location:https://www.whocando.eu/registration.php?fault=nameMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
}elseif (empty($vorName)) {
header("Location:https://www.whocando.eu/registration.php?fault=vorNameMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (empty($email)) {
header("Locationhttps://www.whocando.eu/:registration.php?fault=emailMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (empty($uni)) {
header("Location:https://www.whocando.eu/registration.php?fault=uniMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
}elseif (empty($geburtstag)) {
header("Locationhttps://www.whocando.eu/:registration.php?fault=gebMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (empty($password)) {
header("Location:https://www.whocando.eu/registration.php?fault=passwordMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} elseif (empty($confirmedPassword)) {
header("Location:https://www.whocando.eu/registration.php?fault=confirmedPasswordMissing&name=".$name."&vorname=".$vorName."&email=".$email."&uni=".$uni."&gebDatum=".$geburtstag);
} else {
include ('dbConnection.php');
$date = date("Y-m-d H:i:s",time());
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);
$sqlCode = "INSERT INTO db764570417.logindata (name,email,password)
VALUES (?,?,?)";
$userNameDB = $vorName."".$name;
$statement = $mysqli->prepare($sqlCode);
$statement->bind_Param('sss',$userNameDB,$email,$hashedPassword);
$statement->execute();
$newUserId = $mysqli->insert_id;
$_SESSION['userID'] = $newUserId;
$sqlCode = "INSERT INTO db764570417.userdata (ID,name,firstName,firstLogin,lastLogin,birthDate,email,university)
VALUES (?,?,?,?,?,?,?,?)";
$statement = $mysqli->prepare($sqlCode);
$statement->bind_Param('isssssss',$newUserId,$name,$vorName,$date,$date,$gebDatum,$email,$uni);
$statement->execute();
//header("Location:index.php");
$userID = $newUserId;
$userFirstName[$userID] = $vorName;
$userName[$userID] = $name;
}
}
?>
如果我加载页面，则不会创建会话 ID，但如果我在 localhost 上测试完全相同的代码，它就可以工作。 我认为服务器有问题并使用以下代码上传了一个文件：
<?php
if (!isset($_SESSION)) {
session_start();
echo session_status();
echo "SessionID: ".session_id();
}
echo "SessionID: ".session_id();
?>
我现在完全糊涂了，不知道自己犯了什么错误。
有人可以帮我解决这个问题吗？
谢谢！
【问题讨论】：
-
启用错误报告php.net/manual/en/function.error-reporting.php 看到您正在使用它会返回什么？
-
检查 /tmp/ 目录及其权限。
-
您在本地主机上运行的 PHP 版本是否与您的服务器相同？
-
检查查询中的错误，我们不知道这些函数的作用。您还应该在每个标题后添加
exit;。 -
HTTP 标头的内容必须经过 URL 编码 (
urlencode()) 并且您应该像 Funky49 所说的那样退出程序。
