Session Not Recongised

[IlaminiAyebatonyeDagogo]

I have a script that is not own Originally this written in PHP5 and a little in getting the session value am going to write paste all

login.php

<?php
	session_start();
	
	$error_page = "index.php?error=";
	$success_page = "../main/log.php";

	
	define("PPDIA_APP", 1);
	require_once "../models/db.php";
	require_once "../models/loginModel.php";
	require_once "../models/sessionModel.php";
	
	//Create a new instance of the loginHandler
	$login = new loginModel();
	$login->setDebug();
	
	$login->setCredentials($_POST['username'], $_POST['card_pin']);

	//Authenticate user
	$logged_in = $login->authenticateUser();

	if( $logged_in ) {
		sessionModel::init();
		sessionModel::setParam("user", $login->getDetails());
		
		$location = $success_page;
	}
	else {
		$error_page .= "Your username and pin combination is invalid";
		$location = $error_page;
	}
	
	exit();

	header("Location: {$location}#!/page_jamb utme");
?>

Next is sessionModel.php

<?php
	class sessionModel {
		public static $session_id = "9jsschoo_php_app";
		
		public static function init() {
			session_start();
			$_SESSION[sessionModel::$session_id] = new stdClass();
		}
		
		public static function setParam($param, $data) {
			$_SESSION[sessionModel::$session_id]->$param = $data;
		}
		
		public static function resetParam($param) {
			unset( $_SESSION[sessionModel::$session_id]->$param );
		}
		
		public static function getParam($param) {
			return $_SESSION[sessionModel::$session_id]->$param;
		}
	}

Next is loginModel.php

<?php
	class loginModel extends db
	{
		private $credentials;
		private $enc_pass;
		private $details;
		
		function loginModel() {
			parent::__construct();
			$credentials = new stdClass();
		}
		
		function setCredentials($username, $password) {
			$this->credentials->username = $username;
			$this->credentials->password = $password;
			$this->enc_pass = $this->encryptPass($password);
		}
		
		function authenticateUser() {
			$check = $this->fetchData("", "#__users", "username", $this->credentials->username, "password", $this->enc_pass);
			
			if( !empty($check) ) {
				$this->details = (object) $check[0];
				
				return true;
			}
			else {
				return false;
			}
		}
		
		function getDetails() {
			return $this->details;
		}
	}

Thanks I Just want the session to use on another file that need session to work may be

the file that need the session is below

<?php
// PHP Script Chat - coursesweb.net

define('MAXROWS', 30);             // Maximum number of rows registered for chat
define('CHATLINK', 1);             // allows links in texts (1), not allow (0)

// Here create the rooms for chat
// For more rooms, add lines with this syntax  $chatrooms[] = 'room_name';
$chatrooms = array();
$chatrooms[] = 'English';
$chatrooms[] = 'Government';
$chatrooms[] = 'Economics';
$chatrooms[] = 'Commerce';
$chatrooms[] = 'C.R.K';


// password used to empty chat rooms after this page is accessed with ?mod=admin
define('CADMPASS', 'adminpass');

/* For example, access in your browser
    http://domain/chatfiles/setchat.php?mod=admin
*/


// If you want than only the logged users to can add texts in chat, sets CHATADD to 0
// And sets $_SESSION['username'] with the session that your script uses to keep logged users
define('CHATADD', 0);
if(CHATADD !== 1) {
  if(isset($_SESSION["9jsschoo_php_app"])) define('CHATUSER', $_SESSION["9jsschoo_php_app"]);;
}

// Name of the directory in which are stored the TXT files for chat rooms
define('CHATDIR', 'chattxt');

include('texts.php');             // file with the texts for different languages
$lsite = $en_site;                // Gets the language for site

if(!headers_sent()) header('Content-type: text/html; charset=utf-8');         // header for utf-8

// include the class ChatSimple, and create objet from it
include('class.ChatSimple.php');
$chatS = new ChatSimple($chatrooms);

// if this page is accessed with mod=admin in URL, calls emptyChatRooms() method
if(isset($_GET['mod']) && $_GET['mod'] == 'admin') $chatS->emptyChatRooms();

this is the part where i have to put the session

 if(isset($_SESSION[""])) define('CHATUSER', $_SESSION[""]);;

files that i suppose to contain the session

I guess the question is you want to set the CHATUSER constant to the user's username?

 

If thats the case. Looking at your code when the user logs in successfully you are saving the users data stored in the database into the $_SESSION["9jsschoo_php_app"] variable.

 

Try using

if(isset($_SESSION["9jsschoo_php_app"])) define('CHATUSER', $_SESSION["9jsschoo_php_app"]['username']);

if that doesn't work then what is the output of

printf('<pre>%s</pre>', print_r($_SESSION["9jsschoo_php_app"], 1));
