How to use session - kris - 06-08-2017
Hello
I have the last stable version of codeigniter and try to use session. If someone is not authentified, I display the identification form. Something very classic but...
My session works but only in the same page as soon as I change the page I loose it.
Here is an example
public function __construct()
{
parent::__construct();
$this->load->helper('url');
$this->load->library('session');
$this->load->database();
$this->load->model('user_model');
//session_start();
// on controle ici si une session utilisateur existe
echo "session ok!!!".$this->session->userapp;
$userapp = $this->session->userdata('userapp');
//$userapp = $_SESSION['userapp1'];
echo 'userapp '.$userapp;
/*if($userapp == false || $userapp == NULL || empty($userapp )){
$url = site_url('/login');
echo '<br/><a href='.$url.'>'.$url.'</a>';
quit();
//redirect('login','refresh');
}*/
}
...
it is always empty
and here is my login
function logincheck(){
echo '<br/>session.. '.$this->session->userapp;
$uscode = $this->input->post('identifiant');
$erreur = 0;
if ($data['r'] = $this->user_model->get_1userpercode($uscode)){
if ($data['r']['uspass'] == md5($this->input->post('mdp'))) {
$this->session->set_userdata('userapp', $data['r']['uscode']);
//$_SESSION['userapp1'] = $data['r']['uscode'];
echo "session ok!".$this->session->userdata('userapp');
echo '<br/>session '.$this->session->userapp;
}
else
{
$erreur = 1;
}
}
else
{
$erreur = 1;
}
On this login page, my session is ok I can see the user
What should I do to use session
On the manual I read
Open the application/config/config.php file with a text editor and set your base URL. If you intend to use encryption or sessions, set your encryption key.
what does that means ? I want to use session what shall I do ? shall I set an encryption key ? How ?

I must add information
On local session works well
On my host (dreamhost) it doesn't work. Each time I refresh my screen I have a new session.
I tryed with php session not CI session and it works. I had php7 it didn't work I change to php56 and it is the same. I will use classic php session if I don't find any solution
RE: How to use session - kris - 06-09-2017
No finaly with normal session it does not work. My session is lost. I cannot use session I don't know why. My project is locked. The only solution is to find an other host that keep session. I cannot make authentification ????
Do you have an idea ? I am completely lost

When you change page, do you go from http://www to http://, if so that could be a reason why your session is lost.

if session does not work how to create an authentification system ? With cookies ????

Autoload the session library and read about sessions in the CodeIgniter Users Guide.
RE: How to use session - kris - 06-09-2017
I red the documentation and follow it. It works localhost but as soon as I install on the production serveur. The session does not stay the same each time I refresh I have a new session.
What do you mean my autoload ?
I have this in my code
$this->load->library('session');
RE: How to use session - Krycek - 06-09-2017
InsiteFX means in /config/autoload.php
RE: How to use session - kris - 06-11-2017
how to do it. I want to go forward. 2 weeks now 3 weeks and I cannot use session in my productive server

Looks to me like you reset the session everytime. Best is to set only once using if set checker.
If(!isset($this->session->userdata('auth'))){
Set the session here
}
