One way to write custom validation rule in Laravel is by calling Artisan method make:rule:
php artisan make:rule EmptyIf
Then I don't know how to handle parameters. "Parameters" means something like require_if:foo,bar. The \Illuminate\Contracts\Validation\Rule interface has only two arguments for passes function:
public function passes($attribute, $value);
So I can't understand where I should add parameters. I know I can extends the validator via a Service provider, just like this:
Validator::extend('foo', function ($attribute, $value, $parameters, $validator) {
//
});
But it seems it's an old way, and in my point of view a bit more messy. Is there a way to handle parameter in passes function of a Rule?
