ErrorException Undefined variable when trying to show data in view - php

Question

So i was trying to display a record from a database with laravel, and i have defined the variable in #foreach statement but when i run it it shows ErrorException Undefined variable , although all variable already inside the foreach statement, am i missing a method function in my controller?
this is the view
welcome.blade.php
<div class="blog-item">
<div class="blog-text text-box text-white">
#foreach ($guestbooks as $guestbook)
<div class="top-meta">{{ Carbon\Carbon::parse($guestbook->created_at)->format('d-m-Y') }} / di Rakitan</div>
<h3>{{ $guestbooks->name }}</h3>
<p>{!! \Illuminate\Support\Str::words($guestbook->message, 50, '...') !!}</p>
Lanjutkan Baca <img src="asset/img/icons/double-arrow.png" alt="#"/>
</div>
</div>
<!-- Blog item -->
<div class="blog-item">
<div class="blog-text text-box text-white">
<div class="top-meta">{{ Carbon\Carbon::parse($guestbook->created_at)->format('d-m-Y') }} / di Rakitan</div>
<h3>{{ $guestbook->name }}</h3>
<p>{!! \Illuminate\Support\Str::words($guestbook->message, 50, '...') !!}</p>

<!-- Blog item -->
<div class="blog-item">
<div class="blog-text text-box text-white">

#endforeach
</div>
</div>
this is the controller
GuestbookController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Guestbook;
class GuestbookController extends Controller
{
public function index()
{
$guestbooks = Guestbook::get();
return view('post.post_textarea',[
'guestbooks' => $guestbooks
]);
}
public function store(Request $request)
{
Guestbook::create([
'name' => $request->name,
'message' => $request->message
]);
return redirect()->back();
}
}
and this is the routes
Route::get('/posting','GuestbookController#index')->name('guestbook');
Route::post('/posting','GuestbookController#store')->name('guestbook.store');

Answer 1

Your GuestbookController function index() is returning a view called post.post_textarea and passing your $guestbook variable to that view, while you are trying to get that variable in your welcome.blade.php.
Change your index function to return welcome view like this:
public function index()
{
$guestbooks = Guestbook::get();
return view('welcome',[
'guestbooks' => $guestbooks
]);
}

Answer 2

i figured the problem was that there are two routes routing into the same url as Route::get('/posting','GuestbookController#index')->name('guestbook'); so i delete the other one and it works thanks about that typo tough #Denis Ćerić
