私のウェブサイトで$ _SESSION変数に問題があります。何らかの理由で、私はページをリロードするたびに、または私がウェブサイトの別のセクションを参照すると、自分自身をリセットするように見えます。
私はいくつかの異なるファイルを持っています。
サイトのセッションは、「config.php」ファイルで開始されます。
config.phpの
<?php
// Start Session
session_start();
// Turn on all error reporting
ERROR_REPORTING(E_ALL);
ini_set('display_errors', 1);
require_once('classes/database.php');
$link = new DATABASE;
// Include User info
require_once('classes/user.php');
// Create instance for user class
$activeUser = new USER($link);
?>
のindex.phpは、最初のログイン画面を持っています。また、USERSクラスの関数を呼び出して誰かがすでにログインしているかどうかを確認します。
のindex.php
<?php
require('config.php');
// Check if user is already logged in
if($activeUser->isLoggedIn()) {
$activeUser->redirect('home.php');
}
// Logging user into system
if(isset($_POST['login'])) {
$username = $_POST['user'];
$password = $_POST['pass'];
if($activeUser->login($username, $password)) {
$activeUser->redirect('home.php');
}
else {
$activeUser->error = "true";
$activeUser->errorMessage = "Username or password is incorrect";
}
}
print_r($_SESSION);
?>

私がしますprint_rで（$ _ SESSION）を入れたので、私はセッションがログイン時に再起動されたことを確認できました。とにかく

私は、問題は、リダイレクト機能やログアウト機能自体のどこかから茎が、私は私の人生のために、なぜを把握することはできませんと信じています。セッションはコンフィグレーションファイルでのみ開始され、必要な場所に含まれています。セッションを破棄するようにサイトに指示する唯一の時間は、ログアウト機能です。ログアウト機能を使用しています。ホームページに
私は本当に人々が提供することができるこの上の任意のヘルプに感謝したいと思います。私はこれを理解しようとするよりもはるかに長い時間を過ごしました。
多くの感謝！
更新：私は新しいPHPファイルを作成し、セッションの更新をテストしました。セッションは私のテストファイルで完全に更新されます。いくつかのより詳細な調査の後
sessionTest.php
<?php
include('config.php');
echo "This is testing " . $_SESSION['test'] . "sessions";
$_SESSION['test'] = "updating ";
//session_destroy();
?>
あなたは3つの他のPHPファイルを別のディレクトリを作成し、中を見てみてくださいそれら。セッションを転送しますか？はい？問題はあなたのPHPにあります。いいえ？たぶん、PHPを再インストールしようとしました... –
申し訳ありませんが、私はフォローしません。 phpファイルを含む新しいフォルダを作成し、セッション変数がそこで動作するかどうかを確認することを意味しますか？ –
はい、まさに実際に –
