how to create site-independent session variables ?

Hey, i can't be sure but i think you need this:

https://docs.phalcon.io/en/latest/reference/session.html#isolating-session-data-between-applications

so how to reference a session variable with this setting ?

you dont need ot change your code. Refencing to your variables is all the same. ( i think :-) )

I wrote this in the public index.php file :

$di->set('session', function () {
    $t = time();
    $session = new Session(
        array('uniqueId' => $t)
    );
    $session->start();
    return $session;
});

Now after loging in then there is a test in a controller :

public function indexAction()
{

    //menu et navigation
    if ( ! $this->session->has('user_code') ) {
        $this->response->redirect('index');
    } else {
        ...
    }
}

The problem is that now the test always goes to the $this->response->redirect('index'); part although it went to the else part before !

So what is wrong ?

do it like this :

$di->set('session', function () {
    $session = new Session(
        array('uniqueId' => 'myapp-1')
    );
    $session->start();
    return $session;
});

then you print_r($_SESSION); you should see entries for this app only.

you can check this one also : https://us3.php.net/manual/en/function.session-name.php

and this: https://stackoverflow.com/questions/5479626/same-domain-different-folder-php-session

i think you might be miss matching sessions and cookie paths

which version of Phalcon does the isolation session setting work ?

https://github.com/phalcon/cphalcon/blob/2.0.0/phalcon/session/adapter.zep

session adapter doesnt exists in 1.x branches so my guess would be after phalcon 2

The version I am using is 2.0.8 , and its build date is Sep 26 2015.

well based on the source code of the adapter setting it up like i mentioned above, and using $this->session->get('my-stored-value'); should be working perfectly.

well .... I didnt find how to work with the session isolation setting , so I created customized functions to create unique session variables according to the site name :

function sessionExists($name) { $di = \Phalcon\DI::getDefault(); $session = $di->getSession(); $tab_script_name = explode("/", $_SERVER['SCRIPT_NAME']); return $session->has($tab_scriptname[1].''.$name); }

function setSession($name, $value) { $di = \Phalcon\DI::getDefault(); $session = $di->getSession(); $tab_script_name = explode("/", $_SERVER['SCRIPT_NAME']); $session->set($tab_scriptname[1].''.$name, $value); }

function getSession($name) { $di = \Phalcon\DI::getDefault(); $session = $di->getSession(); $tab_script_name = explode("/", $_SERVER['SCRIPT_NAME']); return $session->get($tab_scriptname[1].''.$name); }
