TbbcMoneyBundle

Build Status PHP Symfony Downloads Latest Stable Version license

SensioLabsInsight

This bundle is used to integrate the Money library from mathiasverraes into a Symfony project.

This library is based on Fowler's Money pattern

  • This bundle is tested and is stable with Symfony 2.8 and Symfony 3.1

Quick Start

use Money\Money;
use Tbbc\MoneyBundle\Form\Type\MoneyType;

// the money library
$fiveEur = Money::EUR(500);
$tenEur = $fiveEur->add($fiveEur);
list($part1, $part2, $part3) = $tenEur->allocate(array(1, 1, 1));
assert($part1->equals(Money::EUR(334)));
assert($part2->equals(Money::EUR(333)));
assert($part3->equals(Money::EUR(333)));

// a service that stores conversion ratios
$pairManager = $this->get('tbbc_money.pair_manager');
$usd = $pairManager->convert($tenEur, 'USD');

// a form integration
$formBuilder->add('price', MoneyType::class);

Features

  • Integrates money library from mathiasverraes
  • Twig filters and PHP helpers for helping with money and currencies in templates
  • A storage system for currency ratios
  • A ratioProvider system for fetching ratio from externals api
  • Symfony form integration
  • Console commands for different operations
  • A configuration parser for specifying website used currencies
  • Access to the history of currency ratio fetched
  • Money formatter i18n

Table of contents

Installation

Use Composer and install with
$ composer require tbbc/money-bundle

Then add the bundle in AppKernel :

    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Tbbc\MoneyBundle\TbbcMoneyBundle(),
        );
    }

In your config.yml, add the currencies you want to use and the reference currency.

tbbc_money:
    currencies: ["USD", "EUR"]
    reference_currency: "EUR"
    decimals: 2

In your config.yml, add the form fields presentations

twig:
    form_themes:
        - 'TbbcMoneyBundle:Form:fields.html.twig'

You should also register custom Doctrine Money type:

doctrine:
    dbal:
        types:
            money: Tbbc\MoneyBundle\Type\MoneyType

Usage

Money Library integration

use Money\Money;

$fiveEur = Money::EUR(500);
$tenEur = $fiveEur->add($fiveEur);
list($part1, $part2, $part3) = $tenEur->allocate(array(1, 1, 1));
assert($part1->equals(Money::EUR(334)));
assert($part2->equals(Money::EUR(333)));
assert($part3->equals(Money::EUR(333)));

$pair = new CurrencyPair(new Currency('EUR'), new Currency('USD'), 1.2500);
$usd = $pair->convert($tenEur);
$this->assertEquals(Money::USD(1250), $usd);

Form integration

You have 3 new form types (under Tbbc\MoneyBundle\Form\Type namespace):

  • CurrencyType : asks for a currency among currencies defined in config.yml
  • MoneyType : asks for an amount and a currency
  • SimpleMoneyType : asks for an amount and sets the currency to the reference currency set in config.yml

Example :

use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;

// I create my form
$form = $this->createFormBuilder()
    ->add('name', TextType::class)
    ->add('price', MoneyType::class, [
        'data' => Money::EUR(1000), //EUR 10
    ])
    ->add('save', SubmitType::class)
    ->getForm();

Saving Money with Doctrine

Solution 1 : two fields in the database

Note that there are 2 columns in the DB table : $priceAmount and $priceCurrency and only one getter/setter : getPrice and setPrice.

The get/setPrice methods are dealing with these two columns transparently.

  • Advantage : your DB is clean and you can do sql sum, group by, sort,... with the amount and the currency in two different columns in your db
  • Disadvantage : it is ugly in the entity.
<?php
namespace App\AdministratorBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Money\Currency;
use Money\Money;

/**
 * TestMoney
 *
 * @ORM\Table("test_money")
 * @ORM\Entity
 */
class TestMoney
{
    /**
     * @var integer
     *
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var integer
     *
     * @ORM\Column(name="price_amount", type="integer")
     */
    private $priceAmount;

    /**
     * @var string
     *
     * @ORM\Column(name="price_currency", type="string", length=64)
     */
    private $priceCurrency;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * get Money
     *
     * @return Money
     */
    public function getPrice()
    {
        if (!$this->priceCurrency) {
            return null;
        }
        if (!$this->priceAmount) {
            return new Money(0, new Currency($this->priceCurrency));
        }
        return new Money($this->priceAmount, new Currency($this->priceCurrency));
    }

    /**
     * Set price
     *
     * @param Money $price
     * @return TestMoney
     */
    public function setPrice(Money $price)
    {
        $this->priceAmount = $price->getAmount();
        $this->priceCurrency = $price->getCurrency()->getCode();

        return $this;
    }
}

Solution 2 : use Doctrine type

There is only one string column in your DB table. The money object is manually serialized by the new Doctrine type.

1.25€ is serialized in your DB by 'EUR 125'. This format is stable. It won't change in future releases..

The new Doctrine type name is "money".

  • Advantage : The entity is easy to create and use
  • Disadvantage : it is more difficult to directly request the db in SQL.
<?php
namespace App\AdministratorBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Money\Money;

/**
 * TestMoney
 *
 * @ORM\Table("test_money")
 * @ORM\Entity
 */
class TestMoney
{
    /**
     * @var integer
     *
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var Money
     *
     * @ORM\Column(name="price", type="money")
     */
    private $price;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * get Money
     *
     * @return Money
     */
    public function getPrice()
    {
        return $this->price;
    }

    /**
     * Set price
     *
     * @param Money $price
     * @return TestMoney
     */
    public function setPrice(Money $price)
    {
        $this->price = $price;
        return $this;
    }
}

Conversion manager

Convert an amount into another currency

$pairManager = $this->get("tbbc_money.pair_manager");
$usd = $pairManager->convert($amount, 'USD');

Save a conversion value in a DB

use Money\Money;

$pairManager = $this->get("tbbc_money.pair_manager");
$pairManager->saveRatio('USD', 1.25); // save in ratio file in CSV
$eur = Money::EUR(100);
$usd = $pairManager->convert($amount, 'USD');
$this->assertEquals(Money::USD(125), $usd);

Money formatter

<?php

namespace My\Controller\IndexController;

use Money\Money;
use Money\Currency;

class IndexController extends Controller
{
    public function myAction()
    {
        $moneyFormatter = $this->get('tbbc_money.formatter.money_formatter');
        $price = new Money(123456789, new Currency('EUR'));

        // best method (added in 2.2+ version)
        \Locale::setDefault('fr_FR');
        $formatedPrice = $moneyFormatter->localizedFormatMoney($price);
        // 1 234 567,89 €
        $formatedPrice = $moneyFormatter->localizedFormatMoney($price, 'en');
        // €1,234,567.89

        // old method (before v2.2)
        $formattedPrice = $moneyFormatter->formatMoney($price);
        // 1 234 567,89

        $formattedCurrency = $moneyFormatter->formatCurrency($price);
        //
    }
}

Twig integration

{{ $amount | money_localized_format('fr') }} => 1 234 567,89 €
{{ $amount | money_localized_format('en_US') }} => €1,234,567.89
{{ $amount | money_localized_format }} => depends on your default locale
{{ $amount | money_format }}
{{ $amount | money_as_float }}
{{ $amount | money_get_currency | currency_symbol }}
{{ $amount | money_get_currency | currency_name }}
{{ $amount | money_convert("USD") | money_format }}
{{ $amount | money_format_currency }}

PHP templating integration

<span class="price"><?php echo $view['tbbc_money']->format($price) ?></span>
<span class="money"><?php echo $view['tbbc_money_currency']->formatCurrencyAsSymbol($price->getCurrency()) ?></span>

Fetching ratio values from remote provider

# save a ratio in the storage
./bin/console tbbc:money:ratio-save USD 1.25

# display ratio list
./bin/console tbbc:money:ratio-list

# fetch all the ratio for all defined currencies from an external API
./bin/console tbbc:money:ratio-fetch

Change the ratio provider

The ratio provider by default is base on the service 'tbbc_money.ratio_provider.ecb'

This bundles contains three ratio providers :

You can change the service to use in the config.yml file :

tbbc_money:
    [...]
    ratio_provider: tbbc_money.ratio_provider.google

Additional rate providers from Exchanger

This project integrates https://github.com/florianv/exchanger library to work with currency exchange rates from various services.

Installation:

composer require "florianv/exchanger" "php-http/message" "php-http/guzzle6-adapter"

Configuration:

First, you need to add services you would like to use into your services.yml file, e.g:

ratio_provider.service.ecb:
  class: Exchanger\Service\EuropeanCentralBank

Second, you need to update ratio provider used by MoneyBundle on your config.yml file:

tbbc_money:
    [...]
    ratio_provider: ratio_provider.service.ecb

Recommended:

Some providers focus on a limited set of currencies, but give better data. You can use several rate providers seamlessly on your project by bundling them into the chain. If some provider does not support certain currency, next provider in the chain would be attempted.

Example of chained providers:

ratio_provider.service.ecb:
  class: Exchanger\Service\EuropeanCentralBank

ratio_provider.service.rcb:
  class: Exchanger\Service\RussianCentralBank

ratio_provider.service.cryptonator:
  class: Exchanger\Service\Cryptonator

ratio_provider.service.array:
  class: Exchanger\Service\PhpArray
  arguments:
    -
      'EUR/USD': 1.157
      'EUR/AUD': 1.628

ratio_provider.service.default:
  class: Exchanger\Service\Chain
  arguments:
    -
      - "@ratio_provider.service.ecb"
      - "@ratio_provider.service.rcb"
      - "@ratio_provider.service.cryptonator"
      - "@ratio_provider.service.array"

As you can see here 4 providers would be attempted one after another until conversion rate is found. Check this page for a fill list of supported services and their configurations: https://github.com/florianv/exchanger/blob/master/doc/readme.md#supported-services

And then you need to assign rate provider on your config.yml file:

tbbc_money:
    [...]
    ratio_provider: ratio_provider.service.default

Create your own ratio provider

A ratio provider is a service that implements the Tbbc\MoneyBundle\Pair\RatioProviderInterface. I recommend that you read the PHP doc of the interface to understand how to implement a new ratio provider.

The new ratio provider has to be registered as a service.

To use the new ratio provider, you should set the service to use in the config.yml by giving the service name.

tbbc_money:
    [...]
    ratio_provider: tbbc_money.ratio_provider.google

automatic currency ratio fetch

Add to your crontab :

1 0 * * * /my_app_dir/bin/console tbbc:money:ratio-fetch > /dev/null

MoneyManager : create a money object from a float

Create a money object from a float can be a bit tricky because of rounding issues.

<?php
$moneyManager = $this->get("tbbc_money.money_manager");
$money = $moneyManager->createMoneyFromFloat('2.5', 'USD');
$this->assertEquals("USD", $money->getCurrency()->getCode());
$this->assertEquals(250, $money->getAmount());

history of currency ratio with the pairHistoryManager

Doctrine is required to use this feature.

In order to get the ratio history, you have to enable it in the configuration and to use Doctrine.

tbbc_money:
    currencies: ["USD", "EUR"]
    reference_currency: "EUR"
    enable_pair_history: true

Then you can use the service :

$pairHistoryManager = $this->get("tbbc_money.pair_history_manager");
$dt = new \DateTime("2012-07-08 11:14:15.638276");

// returns ratio for at a given date
$ratio = $pairHistoryManager->getRatioAtDate('USD',$dt);

// returns the list of USD ratio (relative to the reference value)
$ratioList = $pairHistoryManager->getRatioHistory('USD',$startDate, $endDate);

RatioStorage

Two storages for storing ratios are available : CSV File, or Doctrine By default, TbbcMoneyBundle is configured with CSV File.

If you want to switch to a Doctrine storage, edit your config.yml

tbbc_money:
    storage: doctrine

Update your database schema :

./bin/console doctrine:schema:update --force

With the Doctrine storage, currency ratio will use the default entity manager and will store data inside the tbbc_money_doctrine_storage_ratios

Custom NumberFormatter in MoneyFormatter

The MoneyFormatter::localizedFormatMoney ( service 'tbbc_money.formatter.money_formatter' ) use the php NumberFormatter class ( http://www.php.net/manual/en/numberformatter.formatcurrency.php ) to format money.

You can :

  • give your own \NumberFormatter instance as a parameter of MoneyFormatter::localizedFormatMoney
  • subclass the MoneyFormatter and rewrite the getDefaultNumberFormater method to set a application wide NumberFormatter

Using the TbbcMoneyBundle without Doctrine

You have to disable the pair history service in order to use the TbbcMoneyBundle without Doctrine.

tbbc_money:
    enable_pair_history: true

Note : you can imagine to code your own PairHistoryManager for MongoDB or Propel, it is very easy to do. Don't hesitate to submit a PR with your code and your tests.

Optimizations

In your config.yml, you can :

  • select the templating engine to use. By default, only Twig is loaded.
  • define the decimals count after a unit (ex : 12.25€ : 2 decimals ; 11.5678€ : 4 decimals)
tbbc_money:
    currencies: ["USD", "EUR"]
    reference_currency: "EUR"
    decimals: 2
    enable_pair_history: true
    ratio_provider: tbbc_money.ratio_provider.yahoo_finance

Note about older versions

  • Examples above use Symfony 3 syntax for the console (./bin/console), for version 2.8 you should use ./app/console instead.
  • "class" constant (e.g. MoneyType::class) is only supported since PHP 5.5, if you have an older version, you should use the full class name instead (e.g. Tbbc\MoneyBundle\Type\MoneyType)
