        USD: "$ %s"

That's it for setup, jump to the next chapter to learn how to use this bundle.

Usage

The main parts of this bundle are a command to update currency rates and Twig helpers to display price in various currencies.

Before converting prices you need to fetch the latest currency rates:

$ app/console ongr:currency:update

Tip: setup a cron job to update currencies daily in your production environment.

Now you are ready to use currency conversion logic in your templates. Here is a simple example how to convert currency:

<ul>
    <li>Price in default currency: {{ 123.123|ongr_price(2) }}
    <li>Price in US dollars: {{ 123.123|ongr_price(2, 'USD') }}
</ul>

In this example the number 2 represents the number of decimal points. It will print the following information:

Price in default currency: 123.12 €
Price in US dollars: $ 123.12
