$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env'); //Your .env file path

Notes: You need to install the MailboxValidator PHP Module in order to use this bundle. You can visit https://github.com/MailboxValidator/mailboxvalidator-php for the source codes.

Usage

Before using the validator, be sure to add the bundle into the config/bundles.php file:

// config/bundles.php
return [
    ...
    MailboxValidatorBundle\MailboxValidatorBundle::class => ['all' => true],
];

The validators available to validate the email are: single, free and disposable. Each validator validate the email by using MailboxValidator API. For more information, you can visit Single Validation API, Disposable Email API and Free Email API.

1. To use any one of three validators or use all of the validators, include the following lines in any form controller that handle the validation:

use MailboxValidatorBundle\Validator\MBVSingle;
use MailboxValidatorBundle\Validator\MBVDisposable;
use MailboxValidatorBundle\Validator\MBVFree;

1. After that, add a new rule to your form field. For example, if you want to validate the disposable email, your rule will be like this:

->add('email', EmailType::class, [
			'constraints' => [
				new MBVDisposable([
					//You can also custom a message yourself. For example,
					//'message' => 'This email is disposable. Please enter another email again.',
					]),
				],
			])
