How to pass value from input textbox to another page in Laravel - php

Question

The indexcontroller is shown below
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class IndexController extends Controller
{
public function index()
{
return view('welcome');
}
public function about()
{
return view('about');
}
public function contact()
{
return view('contact');
}
public function thanks(Request $request)
{
$request->validate(['firstname' => ['required', 'alpha_num']]);
return view('thanks');
}
}
contact.blade.php is below
#extends('welcome')
#section('content')
<div>
<h2>Contact Page</h2>
<form method="post" action="{{route("thanks")}}">
#csrf<input type="text" name="firstname"/>
<input type="submit"/>
</form>
#if ($errors->any())
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
</div>
#endsection
Thanks.blade.php
#extends('welcome')
#section('content')
<div>
<h2>Thanks</h2>Thank you {{ $firstname }}
</div>
#endsection
welcome.blade.php
<div class="flex-center position-ref full-height">
<div class="content">
<div class="title m-b-md">
app
</div>
<div class="links">
About
contact
</div>
<h1>{{$firstname}}</h1>
<div>
#yield('content')
</div>
</div>
</div>
web.php
<?php
Route::get('/', 'IndexController#index');
Route::get('/about', 'IndexController#about')->name('about');
Route::get('/contact','IndexController#contact')->name('contact');
Route::post('/contact','IndexController#thanks')->name('thanks');
When I click on contact in welcome.blade.php it takes me to contact page where the textbox is pressent . The value entered should appear in thankyou.blade.php.
I need the value entered in the textbox to be shown in thanks.blade.php when I click on submit.
Thanks in Advance

Data needs to be passed to a view explicitly. For hopefully obvious reasons, it isn't globally accessible as a variable.
E.g.
return view('thanks', ['firstname' => 'Your First Name']);
