laravel-codicefiscale

laravel-codicefiscale is a package for the management of the Italian CodiceFiscale (i.e. tax code). The package allows easy validation and parsing of the CodiceFiscale. It is also suited for Laravel since it provides a convenient custom validator for request validation.

Important update: now you can dynamically load city codes from ISTAT using the non-default IstatRemoteCSVList city decoder.

• Installation
• Configuration
• Validation
• Utility CodiceFiscale class
• Codice fiscale Generation
• City code parsing
• Integrate your own cities

Installation

Run the following command to install the latest applicable version of the package:

composer require robertogallea/laravel-codicefiscale

Laravel

In your app config, add the Service Provider to the $providers array (only for Laravel 5.4 or below):

'providers' => [
   ...
   robertogallea\LaravelCodiceFiscale\CodiceFiscaleServiceProvider::class,
],

The validation error messages are translated in it and en languages, if you want to add new language please send me a PR.

Lumen

In bootstrap/app.php, register the Service Provider

$app->register(robertogallea\LaravelCodiceFiscale\CodiceFiscaleServiceProvider::class);

Configuration

To customize the package configuration, you must export the configuration file into config/codicefiscale.php.

This can be achieved by launching the following command:

php artisan vendor:publish --provider="robertogallea\LaravelCodiceFiscale\CodiceFiscaleServiceProvider" --tag="config"

You can configure the following parameters:

• city-decoder: the class used for decoding city codes (see City code parsing), default to InternationalCitiesStaticList.
• date-format: the date format used for parsing birthdates, default to 'Y-m-d'.
• labels: the labels used for male and female persons, defaults to 'M' and 'F'.

Language Files

You can customize the validation messages publishing the validation translations with this command:

php artisan vendor:publish --provider="robertogallea\LaravelCodiceFiscale\CodiceFiscaleServiceProvider" --tag="lang"

Validation

To validate a codice fiscale, use the codice_fiscale keyword in your validation rules array

    public function rules()
    {
        return [
            'codicefiscale' => 'codice_fiscale',
            
            //...
        ];
    }

From version 1.9.0 you can validate your codice fiscale against other form fields to check whether there is a match or not.

You must specify all of the required fields:

• first_name
• last_name
• birthdate
• place
• gender

giving parameters to the codice_fiscale rule.

For example:

    public function rules()
    {
        return [
            'codicefiscale' => 'codice_fiscale:first_name=first_name_field,last_name=last_name_field,birthdate=birthdate_field,place=place_field,gender=gender_field',
            'first_name_field' => 'required|string',
            'last_name_field' => 'required|string',
            'birthdate_field' => 'required|date',
            'place_field' => 'required|string',
            'gender_field' => 'required|string|max:1',
            
            //...
        ];
    }

Validation fails if the provided codicefiscale and the one generated from the input fields do not match.

Utility CodiceFiscale class

A codice fiscale can be wrapped in the robertogallea\LaravelCodiceFiscale\CodiceFiscale class to enhance it with useful utility methods.

use robertogallea\LaravelCodiceFiscale\CodiceFiscale;

...
try {
    $cf = new CodiceFiscale();
    $result = $cf->parse('RSSMRA95E05F205Z');
    var_dump($result);
} catch (Exception $exception) {
    echo $exception;
}

In case of a valid codicefiscale it produces the following result:

[
  "gender" => "M"
  "birth_place" => "F205"
  "birth_place_complete" => "Milano",
  "day" => "05"
  "month" => "05"
  "year" => "1995"
  "birthdate" => Carbon @799632000 {
    date: 1995-05-05 00:00:00.0 UTC (+00:00)
  }
]

in case of an error, CodiceFiscale::parse() throws an CodiceFiscaleValidationException, which returns one of the defined constants with $exception->getCode():

• CodiceFiscaleException::NO_ERROR
• CodiceFiscaleException::NO_CODE
• CodiceFiscaleException::WRONG_SIZE
• CodiceFiscaleException::BAD_CHARACTERS
• CodiceFiscaleException::BAD_OMOCODIA_CHAR
• CodiceFiscaleException::WRONG_CODE
• CodiceFiscaleException::MISSING_CITY_CODE

If you rather not want to catch exceptions, you can use CodiceFiscale::tryParse():

use robertogallea\LaravelCodiceFiscale\CodiceFiscale;

...
$cf = new CodiceFiscale();
$result = $cf->tryParse('RSSMRA95E05F205Z');
if ($result) {
    var_dump($cf->asArray());
} else {
    echo $cf->getError();
}

which returns the same values as above, you can use $cf->isValid() to check if the codicefiscale is valid and $cf->getError() to get the error. This is especially useful in a blade template:

@php($cf = new robertogallea\LaravelCodiceFiscale\CodiceFiscale())
@if($cf->tryParse($codicefiscale))
    <p><i class="fa fa-check" style="color:green"></i>{{$cf->getCodiceFiscale()}}</p>
@else
    <p><i class="fa fa-check" style="color:red"></i>{{$cf->getError()->getMessage()}}</p>
@endif

Codice fiscale Generation

Class CodiceFiscale could be used to generate codice fiscale strings from input values:

$first_name = 'Mario';
$last_name = 'Rossi';
$birth_date = '1995-05-05'; // or Carbon::parse('1995-05-05')
$birth_place = 'F205';      // or 'Milano'
$gender = 'M';

$cf_string = CodiceFiscale::generate($first_name, $last_name, $birth_date, $birth_place, $gender);

City code parsing

There are three strategies for decoding the city code:

• InternationalCitiesStaticList: a static list of Italian cities;
• ItalianCitiesStaticList: a static list of International cities;
• IstatRemoteCSVList: a dynamic (loaded from web) list of Italian cities loaded from official ISTAT csv file. Please note that the list is cached (one day by default, see config to change).
• CompositeCitiesList: merge the results from two CityDecoderInterface classes (for example IstatRemoteCSVList and InternationalCitiesStaticList) using the base CityDecoderInterface in the config key codicefiscale.cities-decoder-list.

By default, the package uses the class InternationalCitiesStaticList to lookup the city from the code and viceversa. However you could use your own class to change the strategy used.

You just need to implement the CityDecoderInterface and its getList() method. Then, to use it, just pass an istance to the CodiceFiscale class.

For example:

class MyCityList implements CityDecoderInterface
{
  public function getList()
  {
    // Implementation
  }
}

...
$cf = new CodiceFiscale(new MyCityList)
...

Integrate your own cities

Note: if you find missing cities, please make a PR!

If you want to integrate the cities list, you can use the CompositeCitiesList by merging the results of one of the decoders provided and a custom decoder.

For example:

// conf/codicefiscale.php

return [
  'city-decoder' => '\robertogallea\LaravelCodiceFiscale\CityCodeDecoders\CompositeCitiesList',

  ...
  
  'cities-decoder-list' => [
        '\robertogallea\LaravelCodiceFiscale\CityCodeDecoders\InternationalCitiesStaticList',
        'YourNamespace\MyCustomList',
    ]

where MyCustomList is defined as:

...

class MyCustomList implements CityDecoderInterface
{
  public function getList()
  {
    return [
      'XYZ1' => 'My city 1',
      'XYZ2' => 'My city 2',
    ]
  }
}
