[SOLVED] Replace Laravel's default email validation policy

Replace Laravel's default email validation policy

By default, Laravel's email validation does not fail on invalid email, eg 'example@example'.

$data = ['email' => 'example@example'];
$rules = ['email' => 'email'];
$v = Validator::make($data, $rules); // success

This would be ok, but it should be default:

$data = ['email' => 'example@example'];
$rules = ['email' => 'email:filter'];
$v = Validator::make($data, $rules); // fails

How can I set default e-mail validation policy?

Laravel version is 7.

Solution

I don't think you can override the existing rules, but instead you can try adding new ones in app/providers/AppServiceProvider.php

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        \Validator::extend('email_default', function ($attribute, $value) {
            return filter_var($value, FILTER_VALIDATE_EMAIL) !== false;
        });
    }
}
