Laravel , sessions just work for 1 online user - php

I'm new in laravel
I coded a script that many users may work with
but the problem that I have is this :
when a user like "Helen" signs in she can see her profile
but if next another user like "Maria" logs on , Marias panel will be shown for both of them
I think it means just one session can be active at the same time and the value of session will be for the latest user
and the older users session doesn't expire just the value in the session will be changed , thus she identifies as another user and can see that users profile, and also when a user logs out , because of close of the session , all users will be signed out.
here is my simple code :
public function Login(){
$this->Token();
$pack=Input::all();
try {
$result=DB::table('user')->where('Email','=',$pack['email'])->get();
if (Hash::check($pack['password'], $result[0]->Password)){
session(['there' => $result['0']->Email]);
return redirect('dashboard');
}
return redirect('dashboard')->with('does','wrong password');
}catch(Exception $e){
return redirect('dashboard')->with('does',.$e);
}
}
public function UserType() {
if(!session('there'))
return "Not Logged";
else {
$result = DB::table('user')->where('Email', '=', session('there'))->get();
if($result!=null)
return "User";
}
public function ShowDashboard(){
if($this->UserType()=="Not Logged")
else
return view('pages/dashboard');
}

I am not sure why you are session() to manage user logins... Also, they depend a lot on situations where users are login from the same computer, same browser... cookies... etc etc... and maybe that's why you might be getting 2 different session values at the same time...
In any case.. please try and prefer using Laravel's predefined functions of Auth to handle your login/logout procedures.
public function Login()
{
// What does this do? Check for a CSRF token? If yes, then
// please understand then Laravel automatically checks
// for the CSRF token on POST/PUT requests and therefore
// there is no special need to use the below function...
$this->Token();
$pack = request()->only(['email', 'password']);
// I don't really feel try catch is required here... but completely your choice...
try {
if(auth()->attempt($pack)) {
return redirect('dashboard')
}
return redirect->back()->with('does', 'wrong password');
} catch(Exception $e) {
return redirect->back()->with('does', $e);
}
}
public function ShowDashboard()
{
// You can remove this if/else by adding the 'auth' middleware
// to this route
if(!auth()->check())
return view('pages.dashboard');
else
return redirect(route('login'));
}
I found a lot of problems in your above code...
Please use camelCase for naming functions... (I haven't changed the naming in my code above because I don't really know what rules you are following at your workplace or idk...)
Please don't return strings for a simple true/false situation.
Please try and use Models whenever possible. The raw DB commands are required for very complex and extensive queries

Add Admin role in laravel 5.4

I have a database that in this: Admin has True isAdmin property, but other users have false isAdmin property.
I want to check if the user who logged in is an Admin or not by redirecting them to different pages in my app. My code in Controller is:
public function store(User $user)
{
if (auth()->attempt(request(['email', 'password']))) {
if ($user->isAdmin == 1) {
return redirect('/ShowUser');
}
{
return redirect('/lo');
}
}
return back()->withErrors(
[
'message' => 'Error'
]
);
}
But this code doesn't work; it sends the users to '/lo' all the time. How can I fix it?
You're missing an else keyword.
Right here:
if ($user->isAdmin == 1) {
return redirect('/ShowUser');
}
{ // <-- right here
return redirect('/lo');
}
add the else keyword.
if ($user->isAdmin == 1) {
return redirect('/ShowUser');
}
else { // <-- right here
return redirect('/lo');
}
anyway, your code will still run fine even after the edit above. But I have questions for you:
Is the user assumed to be in the database already?
What is the default value of isAdmin in the database?
Are you passing the isAdmin attribute as an input from a form or something?
And why is it a store request when you're just trying to log a user in?
It's a bit confusing. I can tell from your code that you're trying to log a user in, but you're doing it in a store method (nothing wrong with that, just convention), the store method is usually used in storing data (how coincidental!)

Laravel allow route to be accessible only from another route

I have /signup/select-plan which lets the user select a plan, and /signup/tos which displays the terms of services. I want /signup/tos to be only accessible from /signup/select-plan. So if I try to go directly to /signup/tos without selecting a plan, I want it to not allow it. How do I go about this?
In the constructor, or the route (if you are not using contructors), you can check for the previous URL using the global helper url().
public function tos() {
if ( !request()->is('signup/tos') && url()->previous() != url('signup/select-plan') ) {
return redirect()->to('/'); //Send them somewhere else
}
}
In the controller of /signup/tos which returns the tos view just add the following code:
$referer = Request::referer();
// or
// $referer = Request::server('HTTP_REFERER');
if (strpos($referer,'signup/select-plan') !== false) {
//SHOW THE PAGE
}
else
{
dd("YOU ARE NOT ALLOWED")
}
What we are doing here is checking the HTTP referrer and allowing the page access only if user comes from select-plan
You are need of sessions in laravel. You can see the following docs to get more info: Laravel Sessions
First of all you need to configure till how much time you want to have the session variable so you can go to your directory config/sessions.php and you can edit the fields 'lifetime' => 120, also you can set expire_on_close by default it is being set to false.
Now you can have following routes:
Route::get('signup/select-plan', 'SignupController#selectPlan');
Route::post('signup/select-token', 'SignupController#selectToken');
Route::get('signup/tos', 'SignupController#tos');
Route::get('registered', 'SignupController#registered');
Now in your Signupcontroller you can have something like this:
public function selectPlan()
{
// return your views/form...
}
public function selectToken(Request $request)
{
$request->session()->put('select_plan_token', 'value');
return redirect('/signup/tos');
}
Now in signupController tos function you can always check the session value and manipulate the data accordingly
public function tos()
{
$value = $request->session()->get('select_plan_token');
// to your manipulation or show the view.
}
Now if the user is registered and you don't need the session value you can delete by following:
public function registered()
{
$request->session()->forget('select_plan_token');
// Return welcome screen or dashboard..
}
This method will delete the data from session. You can manipulate this. You won't be able to use in tos function as you are refreshing the page and you want data to persist. So its better to have it removed when the final step or the nextstep is carried out. Hope this helps.
Note: This is just the reference please go through the docs for more information and implement accordingly.

How to determine if a session with same variable is already there in laravel

I am using Laravel framework. There is a function in controller that creates session with name store_id
StoreController.php
function initiate($id)
{
//Some queries
session['store_id' => 'some value'];
}
Now if I run this function on one tab then session::get('store_id') is going on. But if I open another tab in the same browser then again run the function that means session('store_id') will be again set. How do I handle this situation that if there is already a session then it should redirect to it's perspective url.
Okay first of all, Bruuuhhhh been there and done that
Alright, lets begin. you want that if there is already a session with store_id going on then you want user to redirect or send back.
In your controller add this
public function initiate()
{
if(session()->has('store_id'))
{
//What ever your logic
}
else
{
redirect()->to('/store')->withErrors(['check' => "You have session activated for here!."]);
}
}
Most probably you would be wondering that user can just go to other url after /store/other-urls Yess he can.
To avoid this. Add a custom middleware
php artisan make:middleware SessionOfStore //You can name it anything.
In that middleware
public function handle($request, Closure $next)
{
if($request->session()->has('store_id'))
{
return $next($request);
}
else
{
return redirect()->back()->withErrors(['privilege_check' => "You are not privileged to go there!."]);
}
return '/home';
}
in your main store page. Add an anchor tag Stop Service
Now in your web.php
Route::group(['middleware' => 'SessionOfStore'], function()
{
//Add your routes here.
Route::get('/stop', 'StoreController#flushSession');
});
Now you have restrict access to urls and has checked the sessions.
Now in
public function flushSession()
{
//empty out the session and
return redirect()->to('/home');
}
The Laravel session helper has the function has to check this.
if (session()->has('store_id'))
{
// Redirect to the store
}
else
{
// Set the store id
}
The documentation contains all of the possible functions that can be used with the session helper.

Laravel Remember Me cookie not being set

I recently built my first web application using laravel and overall it has been great. I have picked up the framework very easily except for this one issue. I am trying to use the framework's built in authentication. I am able to log in my users for a given request but I am trying to implement the remember me functionality by the Auth::attempt() method passing in true as the second parameter as per the documentation.
I have been trying this method for many hours without any luck. I have seen a video at this url (https://www.youtube.com/watch?v=hYUf6u_txhk#aid=P-a-d6RlOC8) which shows which cookie is set when a user is remembered in the application and this cookie is not being set in my browser when I try to remember my user. The cookie is not being set and my users are not being remembered. Here is my code.
if (Auth::attempt(array('email' => Input::get('email'), 'password' => Input::get('password')), true))
{
$userid = DB::table('users')->where('email', '=', $userdata['email'])->pluck('id');
Auth::login(Auth::user());
if (Auth::check())
{
echo "LOGGGEED IN WOOOOOOO";
}
else {
echo "user not logged in";
}
return Redirect::to('/dashboard/' . $userid);
}
Before the redirect happens here is the page I see
Here is the controller that handles the redirect.
class DashboardController extends BaseController
{
public function showDashboard($userid)
{
if (Auth::viaRemember())
{
echo "WOOOOOOOOOOOOOOOO";
}
else {
echo 'booooooo';
}
if (Auth::check())
{
echo 'YAY LOGGED IN';
}
else {
echo 'BOO AGAIN';
}
$user = User::where('id', '=', $userid)->first();
$subscriptions = $user->subscriptions;
$orders = $user->orders;
return View::make('dashboard', compact('user', 'subscriptions', 'orders'));
}
}
But when the redirect happens and /dashboard/{userid} is loaded you can see in the top left hand corner that my echo statements show the user is not being remembered!
I am so frustrated at this point since this is the last step I need to finish my application and I am embarrassed that the laravel documentation says "Laravel aims to make the implementation simple". I have the entire rest of my application working EXCEPT for this part so I would appreciate any and all help with this issue! If you need anymore information please feel free to ask me.Dashboard page
SOLUTION:
In app/config/session.php in the array my 'driver' key had a value of 'file'. After switching this to 'cookie' everything worked as expected.

Logging out with HTTP Basic Auth in Laravel

I have one user class which consists of two types of users and want to allow different users to go to different pages.
I have created a filter as follows
Route::filter('isExpert', function()
{
$userIsExpert = 0;
$userIsLoggedIn = Auth::check();
if ($userIsLoggedIn && Auth::user()->role == 'expert') {
$userIsExpert = 1;
}
Log::info('Logged in: ' . $userIsLoggedIn . ' && Expert: ' . $userIsExpert);
if ($userIsExpert == 0)
{
Log::info('should be logging out now.');
Auth::logout();
return Auth::basic();
}
});
And routing like so
Route::get('/winners', array('before' => 'isExpert', function()
{
$winners = DB::select('select * from winners');
return View::make('winners.index')->with('winners',$winners);
}));
The thought is this: If it's not an expert, it will logout and redirect to login page. If it is, it will simply continue.
However, Auth::logout(); doesn't ever log out the user.
Question
Why is not Auth::logout() working? I've tried placing it anywhere in the app to no avail.
cheers
I had the same problem, I really couldn't logout the current user... And the answer is simple: Laravel doesn't support logout() with Auth::basic().
There are ways to fix it, but it's not very clean; https://www.google.nl/search?q=logout+basic
This is not a limitation to Laravel, HTTP Basic Authorization is not designed to handle logging out. The client will remain logged in until the browser is closed.
HTTP Basic Authorization really shouldn't be used in any public production environment. Here are some reasons why:
No way to give users a "remember me"-option on the login form.
Password managers have no or lacking support for HTTP Basic Auth, as it is not rendered HTML but a native popup.
Terrible user experience. Putting together a proper login form is well worth the little time it takes.
The only valid case I can think of is to protect public development-subdomains like dev.example.com, but there are better ways to solve that as well.
The easiest way that I've found for that is to redirect to invalid username/password on logout route. Example:
Route::get('admin/logout', function() {
return Redirect::to(preg_replace("/:\/\//", "://log-me-out:fake-pwd#", url('admin/logout')));
});
If you implemented these methods in User.php
/**
* Get the e-mail address where password reminders are sent.
*
* #return string
*/
public function getReminderEmail()
{
return $this->email;
}
public function getRememberToken()
{
return $this->remember_token;
}
public function setRememberToken($value)
{
$this->remember_token = $value;
}
public function getRememberTokenName()
{
return 'remember_token';
}
add new column with name 'remember_token' to your table 'users' in mysql database, and then log out, finally it solved successfully.
to alternate you table use this SQL Command:
ALTER TABLE users ADD remember_token TEXT;
and then press 'Go' button.
