Custom Validation Error Messages In Laravel 9

- Install Laravel 9
- Connecting App to Database
- Run Migration Command
- Add Routes
- Generate Controller By Command
- Create the blade view
- Run Development Server.
Install Laravel 9
First of all we need to create a fresh laravel project, download and install Laravel 9 using the below command
|
1 |
composer create-project --prefer-dist laravel/laravel Blog |
Connecting App to Database,
Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.
|

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=here your database name here DB_USERNAME=here database username here DB_PASSWORD=here database password here |
Run Migration Command
Now, in this step we will create model and migration file. Please run the following command:
|
1 |
php artisan migrate |
Add Routes
After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.
routes/web.php
|
1 2 3 4 5 |
use App\Http\Controllers\CustomErrorController; Route::get('form', [CustomErrorController::class, 'index']); Route::get('store', [CustomErrorController::class, 'store']); |
Generate Controller By Command.
Now, lets create a controller named CustomErrorController using command given below –
|
1 |
php artisan make:controller CustomErrorController |
Once the above command executed, it will create a controller file CustomErrorController.php in app/Http/Controllers/ directory. Open the CustomErrorController.php file and put the following code in it.
app/Http/Controllers/CustomErrorController.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Models\User; class CustomErrorController extends Controller { public function create() { return view('form'); } 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']); $user = User::create($input); return back()->with('success', 'User created successfully.'); } } |
Create Blade View
In this step we will create blade view file. Go to resources/views folder and create a blade view file from.blade.php and update the following code into your file:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 |

Run Development Server.
Now we are ready to run our example so lets start the development server using following artisan command –
|
1 |
php artisan serve |
Now, open the following URL in browser to see the output –
|
1 |
http://localhost:8000/form |
