How to use Presenters

The Presenters are used to display the data for the end user according to their locale. For example, a metric value will be displayed “0.15 Meter” in English and “0,15 Mètre” in French. In this page you will learn how to create your own Presenters or modify predefined formats of default Presenters.

How to register a new Presenter

Several presenters are already defined for prices, metrics, numbers, etc. You can implement your own Presenter to display your custom values.

To create your new Presenter, first create a class implementing Akeneo\Component\Localization\Presenter\PresenterInterface. Next, declare it as a service:

pim_catalog.localization.presenter.my_own_presenter:
    class: '%my_own_presenter_class%'
    tags:
        - { name: pim_catalog.localization.presenter, type: 'product_value' }

You have to tag your service with one of the following types:

• product_value: used to present the ProductValue (e.g. prices, metrics, numbers, etc),
• attribute_option: used to present the attribute options (e.g. the option max_number of the number attributes).

Actually, the Presenter interface displays data according to the user locale, but you can create a Presenter using custom options.

How to modify the predefined formats of default Presenters

You can define your own formats to present dates, datetimes and prices depending on the user’s locale. The formats of date, datetimes and currencies are predefined for a set of languages. When the requested format is not predefined, the fallback is defined by IntlDateFormatter and NumberFormatter.

To add or modify the default formats, you have to add or modify the pim_catalog.localization.factory tags (date.formats, datetime.formats and currency.formats).

For example:

pim_catalog.localization.factory.currency.formats:
    en_US: '¤#,##0.00'
    fr_FR: '#,##0.00 ¤'
