Check if session has expired in Laravel 5.4 - laravel

How do I check if the session has expired in laravel 5.4.
If the session has expired I want to show a message.

You can use the following
if(Auth::check()) {
}

Laravel will Create Session For every user no matter the User is Logged in or not. It will create Token for Specific Session. You can check if the Token Exist or not.
You can check if the token is there or not by the function Session::get('_token');.
But if you are asking if You want to check if User's Session is Expired, You can use Auth::check(). It will return if the Session is Expired or not for the specific user.
For example, If the user is Logged in, It will return True or False. But you can't check if overall Session is Expired or not Because Laravel will create and Store Session For every Single Visit No Matter if the user is Authenticated or not.

laravel 8 jetstream logout

I m using Laravel 8 - Jetstream for Authentification and i set a session variable : session(['isAdmin'=>'true']) on login :
//app\Providers\JetstreamServiceProvider.php
...
public function boot()
{
...
Fortify::authenticateUsing(function(LoginRequest $request){
...
//verifications
session(['isAdmin'=>'true'])
...
}
If The user Logs out in Jetstream (using POST request to /logout) the session('isAdmin') is null.
The problem is what if the user didn't Log out but the session expired , because then the session('isAdmin') will be null but the user is still logged in (he didn't use the POST request to /logout ) .
I can't test this because i don't know if the session variables expire or no in Laravel maybe it's using database for sessions …
Any informations on how does the Laravel session works with the Authentification system in Jetstream ?
on /logout the user gets logged out from the Application and user session reset and hence all session data destroy. like in your case session('isAdmin') is set to null.
In case of session expire and user is not logged out using post request to /logout, then the session will also reset on next request(post session expire). In this case user will be logged out(as session expired) and session data will be destroyed. This works in same way for file and database driver for session.

Check if a specific user is connected | Laravel Auth

I would like to know if there is any way to know if a user is currently active (with the session started) on my page.
I know that Auth::check() exists but it only returns if the Local user is authenticated, I can't use it to ask for any user.
I have modified the LoginController so that, in the login method and in the logout method, the database modifies me and thus know if it has started or has been disconnected.
But this solution becomes useless if the user logs out in another way, for example by closing the browser.
It occurred to me that I could create a kind of setTimeOut event that checks Auth::check() every 10 minutes and if it returns false, modify the database of that user understanding that he is no longer connected. But I do not know how to do it.
Please help me.
You can use the session database so you can check all the logged in users within your platform and its last activity.
here is the session database schema
Schema::create('sessions', function ($table) {
$table->string('id')->unique();
$table->unsignedInteger('user_id')->nullable();
$table->string('ip_address', 45)->nullable();
$table->text('user_agent')->nullable();
$table->text('payload');
$table->integer('last_activity');
});
then adjust your SESSION_DRIVER=database then you'll see all the active/inactive session within your session database.

Using session to reach previous page after login in laravel

I am using Laravel 5.7. For security reasons, I set my laravel application to automatically logout after one hour inactivity. But I want the user log back in the same page before they got kicked out by the system. I try to use Session, but it only store previous url which is the login page url. How can I retrieve that URL before user got automatically logout?
All you need to do is put this in your logout function.
session(['returnUrl' => url()->previous()]);
And then on login function, redirect user to session('returnUrl') and delete session data with session()->forget('returnUrl')
Use this in your login controller
url()->previous()

Nancy & forms authentication: How to invalidate all sessions of a logged in authenticated user?

I am using Nancy Web Framework and forms authentication.
How do I programmatically invalidate all sessions of a logged in authenticated user?
Logging out the
Context.CurrentUser
with
MyNancyModule.Logout()
just invalidates one session,
if the user is logged in from (e.g.) another browser,
this session is still valid.
That is a good thing, but I want to invalidate all sessions after the user changed her/his password.
Thanks in advance!
The easiest way to do this is change the GUID identifier on the user record that your UserMapper maps to from the session cookie - that will automatically invalidate every single session out there for that user, forcing them to log back in and get a new cookie.

Logging out user at session expiry with tank auth & Codeigniter

I use tank_auth to authenticate and log users in to my application developed using Codeigniter. I noticed that when the session expires after the default period, the user remains logged in. In tank_auth's login() function,
if ($this->tank_auth->is_logged_in())
check at the very beginning always returns true.
I'd like to log the user out when the session expires. Please could you point me in the right direction to implement this?
Thanks!
