VATIN bundle

A Symfony bundle for the VATIN library.

Installation

This library is available on Packagist:

$ composer require ddeboer/vatin-bundle

Then add the bundle to your application:

// app/AppKernel.php
public function registerBundles()
{
    return [
        ...
        new Ddeboer\VatinBundle\DdeboerVatinBundle(),
        ...
    ];
}

Usage

Validate number format

Use the validator to validate a property on your models. For instance using annotations:

use Ddeboer\VatinBundle\Validator\Constraints\Vatin;

class Company
{
    /**
     * @Vatin
     */
    protected $vatNumber;

Symfony’s validator will now check whether $vatNumber has a valid VAT number format. For more information, see Symfony’s documentation.

Validate number existence

Additionally, you can check whether the VAT number is in use:

    /**
     * @Vatin(checkExistence=true)
     */
    protected $vatNumber;

The validator will now check the VAT number against the VAT Information Exchange System (VIES) SOAP web service. This service’s availability is rather unreliable, so it’s a good idea to catch the case where it’s unreachable:

use Symfony\Component\Validator\Exception\ValidatorException;

try {
    if ($validator->isValid()) {
        // Happy flow
    }
} catch (ValidatorException $e) {
    // VAT could not be validated because VIES service is unreachable
}

Using the services directly

You can also use this bundle’s services directly. Validate a VAT number’s format:

$validator = $container->get('ddeboer_vatin.vatin_validator');
$bool = $validator->isValid('NL123456789B01');

Additionally check whether the VAT number is in use:

$bool = $validator->isValid('NL123456789B01', true);

To interact with the VIES webservice:

$vies = $container->get('ddeboer_vatin.vies.client');
$checkVatResponse = $vies->checkVat('NL', '123456789B01');
