Custom Validation Error Messages In Laravel
In this step by step guide I will demonstrate you how to use custom validation error messages on laravel forms. Please follow the instruction given below:
- Step 1 – Install Laravel 8 App
- Step 2 – Connecting App to Database
- Step 3 – Run Migration Command
- Step 4 – Add Routes
- Step 5 – Generate Controller By Command
- Step 6 – Create the blade view
- Step 7 – Run Development Server.
Step 1 – Install Laravel 8 App
First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command
|
1 |
composer create-project --prefer-dist laravel/laravel Blog |
Step 2 – 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 |
Step 3 – Run Migration Command
Now, in this step we will create model and migration file. Please run the following command:
|
1 |
php artisan migrate |
Step 4 – 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']); |
Step 5 – 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.'); } } |
Step 6 – 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 |

Step 7: 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 |
