Hi, Dev
In this guide, we'll delve into crafting personalized validation regulations within your Laravel 11 setup.
Laravel comes with a set of default validation rules like email, required, unique, and date. However, if you require a custom validation rule in Laravel, I can walk you through the process.
Let's take an example where we'll craft a custom validation rule named BirthYearRule. We'll integrate an input text box for birth_year and ensure that the user inputs a year between 1980 and the present year, employing our custom validation.
Step for Laravel 11 Make a Custom Validation Rule Example
Step 1: Install Laravel 11
Step 2: Create Route
Step 3: Create Validation Rule
Step 4: Create Controller
Step 5: Create View File
Run Laravel App
Step 1: Install Laravel 11
First of all, we need to get a fresh Laravel 11 version application using the command below because we are starting from scratch. So, open your terminal or command prompt and run the command below:
composer create-project laravel/laravel example-app
Step 2: Create Routes
In this step, we will create two routes: GET and POST for a custom validation rule example. So let's add it.
routes/web.php
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\CustomValidationController;
Route::get('custom-validation', [CustomValidationController::class, 'create']);
Route::post('custom-validation', [CustomValidationController::class, 'store'])->name('custom.validation.post');
Step 3: Create Validation Rule
In this step, we will create a new "BirthYearRule" validation rule that will check if the user enters a valid year. So let's run the command below and update the rule validation file.
php artisan make:rule BirthYearRule
app/Rules/BirthYearRule.php
<?php
namespace App\Rules;
use Closure;
use Illuminate\Contracts\Validation\ValidationRule;
class BirthYearRule implements ValidationRule
{
/**
* Run the validation rule.
*
* @param \Closure(string): \Illuminate\Translation\PotentiallyTranslatedString $fail
*/
public function validate(string $attribute, mixed $value, Closure $fail): void
{
if(!($value > 1980 & $value < date('Y'))){
$fail('The :attribute must be between 1980 to '.date('Y').'.');
}
}
}
Step 4: Create Controller
In this step, we have to create a new controller named CustomValidationController, and we also need to add two methods: create() and store() to that controller. We will use the BirthYearRule validation on the store method, so let's update the following code:
app/Http/Controllers/CustomValidationController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
use App\Rules\BirthYearRule;
class CustomValidationController extends Controller
{
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function create(): View
{
return view('forms');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function store(Request $request): RedirectResponse
{
$validatedData = $request->validate([
'name' => 'required',
'birth_year' => [
'required',
new BirthYearRule()
]
]);
/*
$validatedData['password'] = bcrypt($validatedData['password']);
$user = User::create($validatedData);
*/
return back()->with('success', 'User created successfully.');
}
}
Step 5: Create View File
In the last step, let's create forms.blade.php (resources/views/forms.blade.php) for the creation form and put the following code:
resources/views/forms.blade.php

placeholder="Birth Year">
@error('birth_year')
<span class="text-danger">{{ $message }}</span>
@endif
</div>
<div class="mb-3">

</div>
