Session variables in codeigniter - php

I am starting a session in controller but i am unable to call that session variable in view.
When i am working on localhost its working perfectly but on server there is nothing in that session variable. I am writting my code:=
Controller
if($_REQUEST['username'] == $result['users'][$i]->username && $_REQUEST['pass'] == $result['users'][$i]->password)
{
session_start();
$_SESSION['username'] = $result['users'][$i]->username;
$_SESSION['profilename'] = $result['users'][$i]->profilename;
die;
$_SESSION['password'] = $result['users'][$i]->password;
$_SESSION['id'] = $result['users'][$i]->ID;
echo $_SESSION['id'];
die;
print_r($result['users']);
$url=strtok($_SERVER["REQUEST_URI"],'?');
redirect("$referal?user=profile");
echo "<script>location.href='$referal?user=profile'</script>";
return true;
die;
}
View :
if(isset($_SESSION['username']) && $_GET['action']!='logout'){
?>
<script>alert("hii");</script>
}

First use the built in SESSIOn library for codeigniter. But I had an issue where the session variable didn't get saved/read. Turned out to be a small issue with itself (some session fixation issue). https://github.com/EllisLab/CodeIgniter/wiki/Native-session sorts it out for you

How to check session on page in php?

I have created the session on the login page and stored in a variable.
on the Login page
$_SESSION['user_id'] = $id;
Now I want to check session that exists or not?
On other pages
<?php
if (session_status() == PHP_SESSION_ACTIVE) {
echo 'Session is active';
}
You need to call
session_start();
on top of file to start the session.
To set a value,
$_SESSION['user_id'] = 1;
To check if session exists and not empty
if(!empty($_SESSION))
{
// write code here
}
To check for a particular value is set
if(isset($_SESSION['user_id']))
{
// write code here
}
You can use isset
if (isset($_SESSION['user_id'])) {
echo 'Session is active';
}

Session data lost after page redirect

I'm having problems getting simple session data values to persist after a page redirection. A function checks user data sent via Post and if it matches values in a database it sets session data to the values and redirects to another page:
if ($login_ok) {
//set session data
$_SESSION ['online'] = 1;
$_SESSION ['userid'] = $id;
$_SESSION ['username'] = $name;
//redirect to new page
redirect('start.php');
}
In the new page code the session data is not set. Simple testing returns null values as if the session data wasn't set:
echo 'Session Login Status: ' . $_SESSION ['online'];
echo 'Session UserID: ' . $_SESSION ['userid'];
echo 'Session Username: ' . $_SESSION ['username'];
Replacing the redirect with the above echo statements works correctly. Is the fact that the session data is set and the redirect activated before any page data has loaded mean that the session variables are not assigned?
To ensure an active session is always available, an include file contains this code:
if (session_status() == PHP_SESSION_NONE) {
session_start();
}
Any idea what the issue is here?
Many thanks,
Kw
Check if the session is set before progress with
if isset($_SESSION ['online']) and
isset($_SESSION ['userid']) and
isset($_SESSION ['username'])
{
echo 'Session Login Status: ' . $_SESSION ['online'];
echo 'Session UserID: ' . $_SESSION ['userid'];
echo 'Session Username: ' . $_SESSION ['username'];
} else {
echo 'Redirect to login or Session expired';
}
Instead of redirect try this
$uid = $_SESSION['USERID'];
if (isset($uid) || $uid != NULL)
{
if (!headers_sent()) {
header('Location:main.php');
exit;
}
else {
?>
<script>window.location = 'main.php';</script>
<?php
}
}
This seems to be a server rather than a code issue. Running the code on a localhost server works correctly. Hope this is helpful to people experiencing similar issues.
Saying that, I have no idea how to set the remote server to allow session data. The server has browser based web administration software called cPanel, any suggestions?

sessions value still showing on some pages after deleting the session

My sessions still shows values of sessions that are deleted on some pages. My header has the session start on every page.
<?php session_start(); ?>
I unset my session with:
$key_to_remove = $_POST['key'];
if (count($_SESSION["Carray"]) <= 1) {
unset($_SESSION["Carray"]);
} else {
unset($_SESSION["Carray"]["$key_to_remove"]);
sort($_SESSION["Carray"]);
}
Try This I use this kind of code for destroy session and it's working.
<?php
session_start();
$_SESSION = array();
session_destroy();
if(isset($_SESSION['key']))
{
unset($_SESSION['carry']);
}?>

PHP Session Unsets Itself

my session keeps getting unset, whenever I refresh a page, but when I made a control test it seemed to work fine.
Control(Held data):
<?php
session_start();
echo(var_dump($_SESSION));
$_SESSION['name'] = 'john doe';
?>
Top of index.php
<?php
session_start();
echo(var_dump($_SESSION));
include('utils/utils.php');
?>
Login page:
<?php
session_start();
include('utils.php');
if(isset($_POST['email']) && isset($_POST['password'])){
$email = filter($_POST['email']);
$password = getPwd(filter($_POST['password']));
if(!isset($_SESSION['email']) && !isset($_SESSION['password'])){
if(isAccount($email, $password)){
$key = genAuthKey();
$_SESSION['email'] = $email;
$_SESSION['auth_key'] = $key;
mysql_query("update `users` set `auth-key`= '$key' where `email`='$email'") or die(mysql_error());
print("ok");
}else {
print('error');
}
}else {
print('error');
logOut();
}
}else {
print('error');
}
?>
The code is getting fired, because it updated the auth-key in the table. I honestly have no idea what the issue is.
Also, the session is unset when I reload the index page.
I've got some more information. The pages can hold session data, and retain it, but once another page using session is loaded, it will unset all data.
Check if you use Unicode encoded PHP files with BOM.
PHP is not aware of the BOM. The BOM results in an output before your first <?php so PHP fails to set the related HTTP header for the session cookie.
From the docs:
To use cookie-based sessions, session_start() must be called before
outputing anything to the browser.

php session doesn't work

How it should work:
Index.php is the secured page. It includes check.php, which checks if you have a session = good. If it hasn't, you're not logged in -> log off, remove session. But it doesn't work, it always logs off, like I didn't log in...
index.php
include ‘check.php’;
echo "logged in";
check.php
session_start();
if($_SESSION[‘login’] != ‘good’) {
unset($_SESSION[‘login’]);
unset($_SESSION[‘name’]);
header(‘Location: login.php?logoff’);
exit();
}
Login.php
if(isset($_POST[‘login’])) {
$gb = array();
$gb[‘user1’] = ‘pass1’;
$gb[‘user2’] = ‘pass2’;
if(isset($gb[$_POST[‘username’]]) && $gb[$_POST[‘username’]] == $_POST[‘password’])
{
$_SESSION[‘login’] = ‘good’;
$_SESSION[‘name’] = $_POST[‘name’];
header("Location: index.php");
} else {
header("Location: login.php?wrongpass");
}
} else { ?>
Login Form
<?php } ?>
I hope someone can help me!
You should verify you started the session in login.php.
Put session_start(); in all the pages
You need to have session_start() at the top of all the pages, you havent shown the session start for your login page.
(Thanks to Danny for proving I cant type)
Check that you have register_globals is On in your php.ini
First check on the pages you want to use session variables session is start or not and if session is not stat then start it.
and this is the very first line in the php file.
Code for the session checking is :
if(!session_id())
{
session_start();
}
if($count==1){
session_start();
$_SESSION['Username'] = $UserName;
$_SESSION['Password'] = $password;
UpdateOnlineChecker($Session);
header( "Location: http://". strip_tags( $_SERVER ['HTTP_HOST'] ) ."/newHolo/" );
exit;
}
else {
echo "Wrong Username or Password";
}
Look at my code. It checks if the statement is true (for me, if there is one row with a query statement i execute). Then i start a session and basically Ill define global session variables, sned out a query to my database to update the session and then refer through.
you are missing a session_start(); in your if true block.
Use one for action document such as index.php there is code:
session_start();
if(isset($_POST['login']) && isset($_POST['password'])){
// login
header('Location: (here is some page)');
}
if(!isset($_SESSION['user']){
// #todo some action
} else {
require_once('login.php');
}
if(isset($_GET['logout'])){
unset($_SESSION['user']);
header('Location: (here is some page)');
}
I think problem is header:
('location:------.php);
Your hosting server doesn't run this.
You can use this:
echo "<script>window.location.href='-----.php'</script>";
