CRUD - The Create doesn't works - php

Question

I am trying to use the Create button to add an element but the recovery doesn't work. I don't have an error message... However my Delete button works well.
In my AdminController I have this:
class AdminController extends Controller
{
public function getHome(){
$devis = Devis::all()->sortByDesc("created_at");
return view('admin.devis.home', compact('devis'));
}
public function destroy(Devis $devis)
{
$devis->delete();
return redirect('/admin');
}
public function create()
{
return view('admin.devis.create');
}
public function store(Request $request)
{
$request->validate([
'firstname' => 'required',
'lastename' => 'required'
]);
Devis::create($request->all());
return redirect()->route('admin.devis.home')
->with('success', 'un étudiant a été crée');
}
}
I think the Controller is correct.
In my folder View => Admin => Devis I have 2 files:
Home.blade.php
#section('content')
<div class="px-content">
<div class="page-header">
<div class="row">
<div class="col-md-4 text-xs-center text-md-left text-nowrap">
<h1><i class="px-nav-icon ion-android-apps"></i>Listing </h1>
</div>
<hr class="page-wide-block visible-xs visible-sm">
<!-- Spacer -->
<div class="m-b-2 visible-xs visible-sm clearfix"></div>
</div>
</div>
<div class="row">
<div class="panel">
<div class="panel-body">
<div class="table-responsive">
<table class="table">
<thead>
<tr>
<th>Firstname</th>
<th>Lastename</th>
<a class="btn btn-sm btn-success" href="{{ route('devis.create') }}">Create</a>
</tr>
</thead>
#foreach($devis as $item)
<tr>
<td> {{$item->firstname}} </td>
<td> {{$item->lastname}} </td>
<td> <span class="left ion-close"></span></td>
</tr>
#endforeach
</table>
</div>
</div>
</div>
</div>
</div>
#endsection
And create.blade.php
#section('content')
<div class="px-content">
<div class="page-header">
<div class="row">
<div class="col-md-4 text-xs-center text-md-left text-nowrap">
<h1><i class="px-nav-icon ion-android-apps"></i>Devis</h1>
</div>
<hr class="page-wide-block visible-xs visible-sm">
<!-- Spacer -->
<div class="m-b-2 visible-xs visible-sm clearfix"></div>
</div>
</div>
<div class="row">
<div class="panel">
<div class="panel-body">
<div class="table-responsive">
<form class="panel-body" action="/devis" method="POST">
#csrf
<fieldset class="form-group">
<label for="form-group-input-1">FirstName</label>
<input type="text" name="firstname" class="form-control" id="form-group-input-1">
</fieldset>
<fieldset class="form-group">
<label for="form-group-input-1">Lastname</label>
<input type="text" name="lastname" class="form-control" id="form-group-input-1" >
</fieldset>
<button type="submit" class="btn btn-primary pull-right">Create</button>
</form>
</div>
</div>
</div>
</div>
</div>
#endsection
In the routes folder I have this
route::resource('devis','AdminController');
Route::post('/devis', 'AdminController#store');
Route::get('/devis/delete/{devis}', 'AdminController#destroy');
I thank you for your help.

Answer 1

Ok, First, sometimes you use lastname, sometimes you use lastename and validator doesn't recognize because they are different names.
Second, you don't see any errors because you haven't implemented a flash_message to see the errors inside the session.
$request->validate([
'firstname' => 'required',
'lastename' => 'required'
]);
<input type="text" name="lastname" class="form-control" id="form-group-input-1" >

Answer 2

Actually you have issue in the naming when you are validating it through the validate function like below:
it should be
$request->validate([
'firstname' => 'required',
'lastname' => 'required'
]);
instead of:
$request->validate([
'firstname' => 'required',
'lastename' => 'required'
]);
you are using lastename instead of lastname.
Validator method actually should have correct indexes otherwise it will not stored in database.
hope it will help.
