Laravel 9 by default provides many validation rules to validate user inputs either for string value, integer value along with their validation error messages as well. But in several cases we need show custom messages for rules. This article will help you for this.
Let’s get started.
Laravel Installation
Open terminal and run this command to create a laravel project.
composer create-project laravel/laravel myblogIt will create a project folder with name myblog inside your local system.
To start the development server of laravel –
php artisan serveURL: http://127.0.0.1:8000
Assuming laravel already installed inside your system.
Create Database & Connect
To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.
CREATE DATABASE laravel_app;
To connect database with application, Open .env file from application root. Search for DB_ and update your details.
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=laravel_app DB_USERNAME=root DB_PASSWORD=root
Create Controller
Open project into terminal and run this command to create controller file.
$ php artisan make:controller CustomControllerIt will create a file CustomController.php inside /app/Http/Controllers folder.

Open this controller file and write this code into it.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
class CustomController extends Controller
{
public function index()
{
return view('form');
}
public function store(Request $request)
{
$request->validate(
[
'name' => 'required',
'password' => 'required',
'email' => 'required'
],
[
'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 Template File
Next,
Create a fie form.blade.php inside /resources/views folder.
Open form.blade.php and write this code into it.

Add Route
Open web.php from /routes folder. Add these routes into it.
//...
use App\Http\Controllers\CustomController;
Route::get('form', [CustomController::class, 'index'])->name('form');
Route::post('store', [CustomController::class, 'store'])->name('store');
//...
Application Testing
Run this command into project terminal to start development server,
php artisan serveURL: http://127.0.0.1:8000/form
Above route will open a form with these input fields – Name, Email, & Password. If you submit this form without any value, then form validations will work and gives you the custom messages what you set from controller.
Once, you submit form with all input data then form will be submitted with success message.
