We wil define custom error messages in laravel 7/6 form validation. You can display error message with each field. I will use has() for checking is error message in laravel 7/6.

here i Will explain simple example of form validation.you can simply use in your laravel 7/6 project.

Step: 1 Create Route

Here we are easy example of validation in laravel 7/6 so just add following both route in your web.php file.we need to create route for Form Validation layout file

following path:/routes/web.php

 
Route::get('client/create', '[email protected]'); 
Route::post('client/store', '[email protected]')->name('client.store');

Step: 2 Create Controller

php artisan make:controller ClientController

now this step, this controller will manage form validation layout bellow content in controller file.following fille path

following path:/app/Http/Controllers/ClientController.php

 
<?php 
 
namespace App\Http\Controllers; 
 
use Illuminate\Http\Request; 
use App\Client; 
 
class ClientController extends Controller 
{  /** 
  * Show the application dashboard. 
  * 
  * @return \Illuminate\Http\Response 
  */ 
  public function create() 
  { 
  	return view('createClient'); 
  } 
  /** 
  * Show the application dashboard. 
  * 
  * @return \Illuminate\Http\Response 
  */ 
  public function store(Request $request) 
  { 
  	  $request->validate([ 
	        'name' => 'required', 
	        'password' => 'required|min:5', 
	        'email' => 'required|email|unique:users' 
	    ], [ 
	        'name.required' => 'Name is required', 
	        'password.required' => 'Password is required' 
	    ]); 
 
  	  $input = $request->all(); 
  	  $input['password'] = bcrypt($input['password']); 
  	  Client::create($input); 
 
  	  return back()->with('success', 'User created successfully.'); 
  } 
}
