min:- Validate minimum character length.
max:- Validate maximum character length.
email: It set input must be a valid email address.

Laravel 9 Form Validation Example
In this step by step tutorial I’ll show you how to implement validations in laravel form.
- Download Laravel 9 Application
- Setup Database with App
- Create Model & Migration
- Create Form Routes
- Create Form Controller By Artisan Command
- Create Form Blade File
- 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 larablog |
Configure Database In .env file
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.
|
1 2 3 4 5 6 |
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=larablog DB_USERNAME=root DB_PASSWORD= |
Create Model & Migration
Now, in this step we will create model and migration file for form. Please run the following command:
|
1 |
php artisan make:model Employee -m |
Once above command is executed there will be a migration file created inside database/migrations/ directory, just open create_employees_table.php migration file and update the function up() method as following:
|
1 2 3 4 5 6 7 8 9 10 11 |
public function up() { Schema::create('employees', function (Blueprint $table) { $table->id(); $table->string('name'); $table->string('email'); $table->string('contact_no'); $table->string('age'); $table->timestamps(); }); } |
Now, run the migration to create database table using following artisan command:
|
1 |
php artisan migrate |
Create Form 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 |
use App\Http\Controllers\FormController; Route::get('form', [FormController::class, 'index']); Route::post('store-form', [FormController::class, 'store']); |
Create Form Controller By Artisan Command
Next, we have to create a controller to display form and to handle form validation and submit operations. Lets Create a controller named FormController using command given below –
|
1 |
php artisan make:controller FormController |
Open the FormValidationController.php file and put the following code in it.
app/Http/Controllers//FormController.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 34 35 36 37 38 |
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Models\Employee; class FormController extends Controller { public function index() { return view('form'); } public function store(Request $request) { $validatedData = $request->validate([ 'name' => 'required', 'email' => 'required|unique:employees|max:255', 'age' => 'required', 'contact_no' => 'required|unique:employees|max:255', ]); $emp = new Employee; $emp->name = $request->name; $emp->email = $request->email; $emp->age = $request->age; $emp->contact_no = $request->contact_no; $emp->save(); return redirect('form')->with('status', 'Form Data Has Been validated and insert'); } } |
Create Form Blade File
Now, create form blade view file to display form and submit to database. So, Go to resources/views and create form.blade.php and update the following code into it:
|
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 |

The following below code will display validation error message on blade view file:
|
1 2 3 |
@error('name') <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div> @enderror |
Start 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 –
http://localhost:8000/form
