Laravel Email Validation letting "user@hotmail" through

Question

I am using Laravel's Validation through FormRequest. An extract of the code is here. It seems laravel's validation is letting email addresses like "user@hotmail" through.

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class DirectorForm extends FormRequest
{
    public function rules()
    {
        return [
            'email' => 'required|email',
        ];
    }
}

it seems the above validation allows "username@hotmail", which isn't a valid email address.

Did i set it up wrongly

that is a valid email address format. a regex can only do so much — Daniel A. White, Apr 17 '19 at 15:02

Actually user@hotmail is a valid email, as user@localhost can also be a valid email address.
If you want to check that if the email address also contains a TLD, you can try:

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class DirectorForm extends FormRequest
{
    public function rules()
    {
        return [
            'email' => 'required|regex:.+@.+\..+',
        ];
    }
}

For more regex email validation rules take a look at this answer.

Use the regex from: https://emailregex.com/

And combine with Laravel regex rule: https://laravel.com/docs/5.8/validation#rule-regex

You can write custom validation for an email in AppServiceProvider like

Boot method

Validator::extend('email_address', function ($attribute, $value, $parameters, $validator) {
            return (!preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix", $value)) ? FALSE : TRUE;
        });

Rules

public function rules()
    {
        return [
            'email' => 'required|email_address',
        ];
    }
