This article goes in detailed on laravel 8 form validation tutorial. We will look at example of laravel 8 form validation with error message. if you have question about form validation laravel 8 then i will give simple example with solution.

You can also define custom error messages in laravel 8 form validation. we will display error message with each field. we will use has() for checking is error message in laravel 8.

Here, i am going to show you very simple example of form validation so, you can simply use in your laravel 8 project.

Create Routes:

Here we are learning simple and easy example of validation in laravel 8 so just add following both route in your web.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\HomeController;
  
Route::get('user/create', [ HomeController::class, 'create' ]);
Route::post('user/create', [ HomeController::class, 'store' ]);

Create Controller:

Now we will add two controller method, one will just display blade file with get request, and another for post request, i write validation for that, so simply add both following method on it.

app/Http/Controllers/HomeController.php

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

Create Blade File:

now here we will create createUser.blade.php file and here we will create bootstrap simple form with error validation message. So, let's create following file:

resources/views/createUser.blade.php
