Session put does not seem to be working properly

Question

I'm working with Laravel 5.8 and I wanted to make sure that users can submit a form only every 2 hours (as long as a session is alive).

So I tried this at the Controller:

if(Session::has('request_has_been_sent')){
    return redirect()->back()->with('error', 'You just submitted a request and cannot submit a new one');
}else{
    $withDraw = WithdrawWallet::create([
        'balance_value' => $request->balance_wallet,
        'can_draw' => $request->can_draw,
        'shaba_number' => $request->shaba_number,
        'first_name' => $request->first_name,
        'last_name' => $request->last_name,
        'description' => $request->desc,
        'status' => 'pending',
        'user_id' => auth()->user()->usr_id,
    ]);
    Session::put('request_has_been_sent');
}

return redirect()->back()->with('success','Your request was sent');

So by this, everytime a user submits a new request, session request_has_been_sent must be set.

Therefore at the next time user submits the form, if the session was still alive, the message You just submitted a request and cannot submit a new one appears.

But now the problem is it does not work. In fact user can still submit another request, right after submitting a request.

This means that the session is not set somehow.

So what's going wrong here? How can I properly do this?

@Milad It should expired itself after 2 hours. I want this session to be forgotten automatically. — Pouya, Nov 24 '21 at 11:27
@Milad It is set to `'lifetime' => env('SESSION_LIFETIME', 120),` at config/session.php — Pouya, Nov 24 '21 at 11:33
if you did any change in config file try `php artisan optimize` to reload the cache — Milad, Nov 24 '21 at 11:35
@Milad I didn't change anything, it was in default settings. And the main question here is that the session is not initialized at all! — Pouya, Nov 24 '21 at 11:36
ok, did you try to add session with value as I see you dont have any value Ex: `Session::put('Hi', '1')` and then `Session::has('Hi')` — Milad, Nov 24 '21 at 11:39
@Milad Thanks it showed the message but does not prevent user from creating a new record. A new record was added again to the DB! — Pouya, Nov 24 '21 at 11:43

You can set session using set and put method

Session::put('name','value');

Retrieve it using get

Session::get('name')

So in your case you need to set your session use

Session::put('request_has_been_sent','yes');

And to check if it is set or not use

if(Session::get('request_has_been_sent')){

It is surprisingly that `Session::has()` does not work for checking session in this case !! – Pouya Nov 24 '21 at 11:52
@nagidi Session::has() checks if the session is set before without any value also it will return true if it is set. but using Session::get() will retrieve value of session. so if it doesnt have any value then it will return false. In your case you need to make sure to remove value from session `request_has_been_sent` after 2 hours. – Leena Patel Nov 24 '21 at 11:55

I think your only problem here is not setting the session value to anything you need to set it to something or else laravel will ignore it.

Session::put('request_has_been_sent', true);

// Check if it exists, this will check if it exists without getting it
Session::has('request_has_been_sent')

Once the user is logged out al the user sesion wil be flushd out. Which means user and create and WithdrawWallet and logout and then login again and then user can create another WithdrawWallet so to fix that you can use cache

$cacheKey = WithdrawWallet::class.'.'.auth()->user()->usr_id;

    if (Cache::has($cacheKey)) {
        return redirect()->back()->with('error', 'You just submitted a request and cannot submit a new one');
    } else {
        $withDraw =  Cache::remember($cacheKey, now()->addHours(2), function () use ($request){
            return  WithdrawWallet::create([
                'balance_value' => $request->balance_wallet,
                'can_draw' => $request->can_draw,
                'shaba_number' => $request->shaba_number,
                'first_name' => $request->first_name,
                'last_name' => $request->last_name,
                'description' => $request->desc,
                'status' => 'pending',
                'user_id' => auth()->user()->usr_id,
            ]);
        });
    
    }

    return redirect()->back()->with('success', 'Your request was sent');
