Get All Connected Users (Laravel 5) - authentication

Question

How to display all connected users in my home?

Answer 1

This is a very basic, but hopefully an efective way to detect both Guest and Registered users on your Laravel5 application.
Step 1
Open the file config/session.php and change the driver to database.
Step 2
We need to create the sessions table, so use the following artisan command php artisan session:table to generate the migration file.
Step 3
On this newly generated migration, you need to add a new user_id column, this is so we can relate the session to a user, if that user is logged in of course.
Open the file migrations/xxxx_xx_xx_xxxxxx_create_session_table.php and add the following inside the Schema::create:
$t->integer('user_id')->nullable();
Here is how the full migration should look:
<?php
use Illuminate\Database\Migrations\Migration;
class CreateSessionTable extends Migration {
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('sessions', function($t)
{
$t->string('id')->unique();
$t->text('payload');
$t->integer('last_activity');
$t->integer('user_id')->nullable();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::drop('sessions');
}
}
Step 4
Run composer dump-autoload and php artisan migrate.
Note: If you don't have Composer installed globally, just use php composer.phar dump-autoload.
Step 5
Save the Eloquent Model somewhere on your application as Session.php.
Note: The recommended place to save this is on the app directory.
Step 6
Now you just need to know how to use it.

Usage
Place the following Session::updateCurrent(); somewhere on your code, as this will make sure that the session entry for the current user get's updated, just an example, you can place it on your app/routes.php file.
Get all users (Guests + Registered)
$all = Session::all();
If you need to check all users online for a certain period, like 10 minutes, you need to call the activity(:limit) method, like so:
$all = Session::activity(10)->get();
Note: This method can be used in combination with the guests() and/or registered() methods.
Guest Users
Grab all
$guests = Session::guests()->get();
Get the # of Guest users
$total = Session::guests()->count();
Registered Users
Grab all
$registered = Session::registered()->get();
foreach ($registered as $online) {
// You can retrieve the user information using something like:
var_dump($online->user->email);
}
Get the # of Registered users
$total = Session::registered()->count();
Eloquent model:
use Carbon\Carbon;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Session;
use Illuminate\Database\Eloquent\Builder;
use Cartalyst\Sentinel\Laravel\Facades\Sentinel;
class Session extends Model
{
/**
* {#inheritdoc}
*/
public $table = 'sessions';
/**
* {#inheritdoc}
*/
public $timestamps = false;
/**
* Returns the user that belongs to this entry.
*
* #return \Cartalyst\Sentinel\Users\EloquentUser
*/
public function user()
{
return $this->belongsTo('Cartalyst\Sentinel\Users\EloquentUser');
}
/**
* Returns all the users within the given activity.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #param int $limit
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeActivity($query, $limit = 10)
{
$lastActivity = strtotime(Carbon::now()->subMinutes($limit));
return $query->where('last_activity', '>=', $lastActivity);
}
/**
* Returns all the guest users.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeGuests(Builder $query)
{
return $query->whereNull('user_id');
}
/**
* Returns all the registered users.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeRegistered(Builder $query)
{
return $query->whereNotNull('user_id')->with('user');
}
/**
* Updates the session of the current user.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeUpdateCurrent(Builder $query)
{
$user = Sentinel::check();
return $query->where('id', Session::getId())->update([
'user_id' => $user ? $user->id : null
]);
}
}
Alternatively you can try this.
