Session still submitted after redirecting view

Question

I am working on an Online Store project using Laravel 5.8 and in this project I have added a checkbox for checking if user wants to pay the price by his online wallet:

<input class="form-check-input" type="checkbox" name="pay_wallet" value="1" id="defaultCheck2">
<label class="form-check-label small mr-3" for="defaultCheck2">
    Pay with Wallet
</label>

Then at the Controller, I added this for submitting a session, if the user checked the checkbox:

try {
   if ($request->pay_wallet == '1') {
      Session::put('wallet', 'payment');
      return redirect()->back();
   }
}catch (\Exception $e) {
   dd($e);
}

Then at the View, I tried this:

@php
if(session('wallet')){
    $us_id = Auth()->user()->usr_id;
    $user_wallet = App\UserWallet::where('user_id', $us_id)->get();
    foreach($user_wallet as $uw){
        echo "
        <ul>
            <li>$uw->id</li>
            <li>$uw->balance</li>
        </ul>
        ";
    }
}
@endphp

Basically what I need to do here is to check, if the session wallet was submitted, show all the available wallets based on his User Id.

But now the problem is, when I refresh the page, it still shows the wallets. Meaning that the session wallet is still alive!

How can I solve this problem?

Answer 1

First, while we set Session, it will keep value till session is destroyed or you use Session::forget('wallet'). But you need that available for only once you load page.

For that you can use Laravel Flash message available by session. Replace your code with this:

try {
   if ($request->pay_wallet == '1') {
      return redirect()->back()->with(['wallet'=>'payment']);
   }
}catch (\Exception $e) {
   dd($e);
}

After that, when you set wallet flag like that. It will be only available for first time when you set then it will get deleted automatically :)
