  • Run this “php artisan make:rule OlympicYear
  • After that command it generates a file app/Rules/OlympicYear.php

    public function passes($attribute, $value)
    return $value >= 1896 && $value <= date('Y') && $value % 4 == 0;
  • Next, we can update error message to be this:
    public function message()
    return ':attribute should be a year of Olympic Games';

    public function store(Request $request)
    $this->validate($request, ['year' => new OlympicYear]);
