Hii @kartik,

Follow are the steps to create custome validation rules in Laravel:

Run this 

"php artisan make:rule OlympicYear"

After that command it generates a file app/Rules/OlympicYear.php

We can write rule in the passes() in OlympicYear.php generated file. It will return true or false depending on condition, which is this in our case

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';
}

Finally, we use this class in controller's store() method we have this code:

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

Thank you!!
