I have upgraded my codeigniter 2.x to 3.0 and I am facing session issue. My site has multi language support so I want to keep language session even when user logout from account. I have implemented logout functionality as mentioned below.
$lang = $this->session->userdata('language');
$this->session->sess_destroy();
$this->session->sess_create();
$this->session->set_userdata(array('language' => $lang));
As CI 3.x sess_create() has been removed so I'm unable to create language session after destroying session. I know we can use cookies helper instead of session but I need to make many changes if I have to use cookies instead of session.
Try below code. Note that here sesssion_var is a variable name in which you are storing your session
$session = $this->session->userdata('sesssion_var');
$language_session = $session['language'];
$this->session->set_userdata('sesssion_var',$language_session);
Use unset_userdata('sessionnamewhichhastobedestroy') rather than sess_destroy().
Or if you use sess_destroy() then set default value in $lang

Here I go what am doing is I am using
Yii::app()->SESSION['userid']
with no
Yii::app()->session->open();
at login
Yii::app()->session->destroy();
at logout
I wanna know if dont do the open and destroy session is it worthy . Does Yii do it internally.
One more strange thing I dont know whats happening. In the same browser for a session I can login for multiple users .. this should not happen so.Is it that i am not using the open and destroy session methods .
public function actionLogout()
{
Yii::app()->user->logout();
Yii::app()->session->clear();
$this->redirect(Yii::app()->controller->module->returnLogoutUrl);
}
Please let me know how do i figure this out
For creating yii session
Yii::app()->session['userid'] = "value";
You can get value like this
$sleep = Yii::app()->session['userid'];
And unset session like
unset(Yii::app()->session['userid']); # Remove the session
In case of user signs out , you have to remove all the session.
Yii::app()->session->clear();
After this, you need to remove actual data from server
Yii::app()->session->destroy();
Don't clear session, only logout:
Yii::app()->user->logout(false);
In YII, the session is handled by 'CHttpSession' class - http://www.yiiframework.com/doc/api/1.1/CHttpSession
Should you use the method 'open()' Yii::app()->session->open(); depends on your configuration. If in the main.php, you have set the
'session' => array (
'autoStart' => true,
), then the Session will be started automatically by YII itself.
You can refer the source code for the method 'init()' here - https://github.com/yiisoft/yii/blob/1.1.16/framework/web/CHttpSession.php#L83
Regarding your question about using the methods 'close()' or 'destroy()', the method 'close()' only unsets the keys of Session but 'destroy' removes the whole session data
Once you craeted session it will allow you in same browser multiple time, i mean for same url it will allow you to login, you can just do it rename your session variable with different name and check that particuller variable to login with that.
Session is a Web application component that can be accessed via Yii::$app->session.
To start the session, call open(); To complete and send out session data, call close(); To destroy the session, call destroy().
Session can be used like an array to set and get session data. For example,
$session = new Session;
$session->open();
$value1 = $session['name1']; // get session variable 'name1'
$value2 = $session['name2']; // get session variable 'name2'
foreach ($session as $name => $value) // traverse all session variables
$session['name3'] = $value3; // set session variable 'name3'
How can I handle user session in symfony? because I'm reading the book of symfony 2 and it says:
Storing and retrieving information from the session can be easily achieved from any controller:
$session = $this->getRequest()->getSession();
// store an attribute for reuse during a later user request
$session->set('foo', 'bar');
// in another controller for another request
$foo = $session->get('foo');
// use a default value if the key doesn't exist
$filters = $session->get('filters', array());
I wonder how to destroy the session. I'm a newbie in symfony so please explain. I'm confused because I found a thread that says its not the way to handle user sessions in symfony2 http://forum.symfony-project.org/viewtopic.php?f=23&t=42766
The link you pointed to is how it used to be until Symfony 2.2 (I think) - that is, it is outdated. Which exact version do you have installed?
You create session by:
$session = new Session();
If you want to invalidate whole session:
$session->invalidate();
of just single value:
$session->remove('some_key');
You can find complete API of Session here.
On every page I see that new session is generated with null userdata
On model constructor
$this->config->set_item('sess_table_name', 'xx_sessions');
Because I want to store this session in another table because the other session table is being used for another login activity
Login function
function login($username,$password)
{
$this->db->where('login',$username);
$this->db->where('pass',$password);
$q=$this->db->get('prof');
// print $this->db->last_query();
if($this->db->count_all_results())
{
$arr=$q->row();
// creating the session
$this->session->set_userdata('login',$arr->id);
$this->session->set_userdata('prof',$arr->profile_id);
// print_r( $arr);
}
else
return FALSE;
}
This login function is on a model. After login and generating the session the page redirects to another page, on that page I see the session builds without any problem but when I move to another page the session losses along with the userdata.
I use the following function to check session data
function print_session()
{
print_r( $this->session->all_userdata());
}
Where I'm wrong ? Tank_auth library and ion_auth library works fine .. I had already used the
Put the session library name into the autoloader configuration, in application/config/autoload.php:
$autoload['libraries'] = array('session');
Then it's available automatically in each controller and everywhere in your application and you get your session data from anywhere:
$session_id = $this->session->userdata('session_id');
And if you don't want to auto load session library then you have to initialize the Session class manually in your controller constructor, use the $this->load->library function:
$this->load->library('session');
For details have a look here:http://ellislab.com/codeigniter/user-guide/libraries/sessions.html
Edit /application/config/config.php and set cookie domain variable
$config['cookie_domain'] = ".yourdomain.com";
It will work!
.yourdomain.com makes the cookie available throughout the domain and its sub-domains.
I have met same problem, and i have searched lots of pages.
I figured out that changing sess_cookie_name solves the problem(new sessions generating issue)
$config['sess_cookie_name'] = 'somenewname'
I just want to know if I am able to hand over session variables from Laravel to my custom code. What I mean is: I want to handle log-in through Laravel and pass it to my profile section which is not in Laravel. Most of the routes are handled by a .htaccess file. The goal is to just login with Laravel auth and save that to $_SESSION['user'] var and redirect to /profile. Somehow I don't get that. The session name is the same in both, in Laravel's session.php's cookie name and my custom code's constant. Is there any other factor I should consider ?
Okay here's the code:
namespace Services\Session;
class OldSessionAuth
{
protected $auth;
function __construct()
{
$this->auth = \Auth::user();
}
public function setSession()
{
$_SESSION['user'] = $this->auth->toArray();
$_SESSION['auth'] = 'TRUE';
return true;
}
public function destroy()
{
session_destroy();
session_unset();
}
}
So, this is sort of my Session services, which is initialized only if it passes the Auth from the controller, Now I think I don't need to do that. so I skiped it, Basic Stuffs (Auth::Check()) really. So, I'd just do this in my login method.
$old = new Services\Session\OldSessionAuth();
$old->setSession();
return Redirect::to('/');
The home page is controlled by my custom made MVC and I want to grab the session, which in this case I can't. It shows Array(). There is no session manipulation when retrieving the session.
Laravel already has a pretty good session abstraction so I don't think you needed to use session_start(), $_SESSION etc directly. Sharing an session across two applications is a bit tricky. If you are tied to using the cookie approach, then you have to make sure that the session driver in use is the cookie one. You would also need to ensure that the restrictions on the cookie aren't such that your other application isn't being sent them by the user's browser.
By default, PHP will use a file cookie driver. In this case, what you would have to do in your other application is to read the "PHPSESSID" cookie, set the session ID using session_id() to this and only then would you have access to the session data using the $_SESSION variable in the other application.
This is all pretty hacky though. I would recommend that if you need to share sessions that you make use of a database session driver instead. This way, you are able to share arbitrary session data across applications using a standard interface. In this case, you would just read the "laravel_session" cookie instead to be able to look up the session in the database. There would be many hidden pitfalls if you then wanted to also modify this data from the other application as well though.
How to set and destroy a session on the controller side?
Tried in the view side, works just fine. But now need it from inside the controller.
UPDATE:
Destroy a Session in Symfony 2 as follows:
$request->getSession()->invalidate(1);
As invalidate leaves the current session untouched if you are not providing any parameter you have to set the lifetime on 1 (one second)
Symfony 3.4 documentation:
http://api.symfony.com/3.4/Symfony/Component/HttpFoundation/Session/Session.html#method_invalidate
Did you try?
/** #var $session Session */
$session = $request->getSession();
$session->remove('name');
Did you try
$this->getAttributeHolder()->remove('foo');
if it was saved in namespace foobar
$user->getAttributeHolder()->remove('foobar','','foo');
At last I found the solution just here around. Use the "session" service explained here: Old post
