Hi Guys,
Today, I will learn you to create validation required in laravel.we will show example of laravel validation required. The field under validation must be present in the input data and not empty. A field is considered "empty" if one of the following conditions are true
- The value is null.
- The value is an empty string.
- The value is an empty array or empty Countable object.
- The value is an uploaded file with no path.
Here, I will give you full example for simply required validation in laravel bellow.
solution$request->validate([ 'rank' => 'required', ]);Route : routes/web.php
Route::get('form/create','FromController@index');
Route::post('form/store','FromController@store')->name('form.store');
Controller : app/Http/Controllers/BlogController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Blade;
use App\Models\User;
use App\Models\Post;
class FromController extends Controller
{
/**
* Write code on Method
*
* @return response()
*/
public function create()
{
return view('form');
}
/**
* Write code on Method
*
* @return response()
*/
public function store(Request $request)
{
$request->validate([
'rank' => 'required',
]);
dd('done');
}
}
