If you are looking for a solution i.e How to return custom validation error messages in Laravel then this article will help you a lot for this. Tutorial is super easy to understand and implement it in your code as well.

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 myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: 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 CustomController

It 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.

                        </div>
                    </form>

            </div>

    </div>

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 serve

URL: 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.
