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


Assuming laravel already installed inside your system.

Register Custom Validation Rule

In this step, we will construct a new “BirthYearRule” validation rule that will validate the user’s birth year. So, use the following command to update the rule validation file.

$ php artisan make:rule BirthYearRule

It will create a file titled BirthYearRule.php inside /app/Rules folder. Open file and write this complete code into it.

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').'.');

Create Application Controller

Open project into terminal and run this command.

$ php artisan make:controller CustomValidation

It will create a CustomValidation.php file inside /app/Http/Controllers folder.

    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' => [
                    new BirthYearRule()
        return back()->with('success', 'User created successfully.');
