README

Money amounts in Symfony forms, validation, Twig templates and Doctrine entities, without floats.

phil/money-bundle brings phil/money into a Symfony application. It keeps the currencies the application accepts, by configuration. It adds a form type that reads an amount in the request's locale without ever going through a float, two validation constraints, a format_money Twig filter with two schema.org functions, and Doctrine mappings that store a currency in one column and an amount in two. It does not convert currencies, fetch exchange rates, round amounts or decide prices: amounts stay in their currency, and an amount finer than its currency is refused rather than rounded.

It is for a Symfony application where an administrator enters prices, a visitor sees them, and entities store them. Code outside Symfony, or a domain layer that only computes, needs phil/money alone.

It is a Symfony bundle. It plugs into the Form and Validator components, into Twig when Twig is installed, and into Doctrine ORM when DoctrineBundle is registered, mapping Money as an embeddable.

The configuration is checked when the container is built, so an unknown currency code stops the kernel with the code named. Every amount crosses the bundle as a Money, from the form field to the database column.

Quick start

composer require phil/money-bundle

# config/packages/phil_money.yaml
phil_money:
    currencies: [CAD, USD]

#[ORM\Embedded(class: Money::class)]

#[MoneyRange(min: '0.01')]
public Money $price;

$builder->add('price', MoneyType::class);

{{ product.price|format_money }}

Requirements
