README

Validate the tax identification numbers with configurable validation constraint.

Requirements

• Symfony validator >=6.1
• PHP >=8.1

For PHP 7.0 & Symfony 3.4, look at v1.x version.

Installation

To download the bundle, require it using the Composer:

$ composer require kreyu/nip-validator-bundle

Usage

Like with all Symfony validation constraints, you can apply it by using annotations:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip()
     */
    private $nip;
}

or by using attributes:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    #[Assert\Nip]
    private $nip;
}

or by using YAML:

App\Entity\Company:
    properties:
        nip:
            - Kreyu\Bundle\NipValidatorBundle\Validator\Constraints\Nip: ~

or by using XML:

<?xml version="1.0" encoding="UTF-8" ?>
<constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping https://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">

    <class name="App\Entity\Company">
        <property name="nip">
            <constraint name="Kreyu\Bundle\NipValidatorBundle\Validator\Constraints\Nip"/>
        </property>
    </class>
</constraint-mapping>

or by using PHP:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints\Nip;
use Symfony\Component\Validator\Mapping\ClassMetadata;

class Company
{
    private $nip;
    
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('nip', new Nip());
    }
}

Pattern validation

By default, the only accepted format is a string of characters without the prefix nor dashes.

Usage of dashes

If you wish to allow or require the usage of the dashes, use the allowDashes and requireDashes options:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     allowDashes=true,
     *     requireDashes=true
     * )
     */
    private $nip;
}

Both options are set to false by default.
Setting the requireDashes option to true ignores the value of the allowDashes, as the number without dashes is no longer valid.
The allowed formats with dashes are following:

• XX-XXX-XXX-XX, e.g. 34-208-769-99
• XXX-XXX-XX-XX, e.g. 342-087-69-99

Usage of prefix

If you wish to allow or require the usage of the prefix, use the allowPrefix and requirePrefix options.
Additionally, it is possible to modify the length of the prefix, using the prefixLength option.

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     allowPrefix=true,
     *     requirePrefix=true,
     *     prefixLength=2     
     * )
     */
    private $nip;
}

Both allowPrefix and requirePrefix options are set to false by default, and prefixLength defaults to 2.
Prefixes are not followed with the space:

• PPXXXXXXXXXX, e.g. PL3420876999

Customization of the pattern violation message

It is possible to customize the pattern violation message using the patternMessage option:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     patternMessage="This is not a valid NIP number."
     * )
     */
    private $nip;
}

You can use the following parameters in this message:

Usage of a custom regular expression

If the default functionality does not meet your needs, consider using the pattern option:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     pattern="/^(\d{2}.\d{3}.\d{3}.\d{2})$/"
     * )
     */
    private $nip;
}

By default this option is equals null, and setting it to any other value ignores the allowDashes, requireDashes, allowPrefix and requirePrefix options.

Checksum validation

By default, the checksum is being validated. If you wish to disable this feature, set the checksum option to false:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     checksum=false
     * )
     */
    private $nip;
}

Customization of the checksum violation message

It is possible to customize the checksum violation message using the checksumMessage option:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     checksumMessage="This is not a valid NIP number."
     * )
     */
    private $nip;
}

You can use the following parameters in this message:

Usage of a callable normalizer

It is possible to define the PHP callable to apply on the value before the validation, using the normalizer option:

<?php

namespace App\Entity;

use Kreyu\Bundle\NipValidatorBundle\Validator\Constraints as Assert;

class Company
{
    /**
     * @Assert\Nip(
     *     normalizer="trim"
     * )
     */
    private $nip;
}
