Displaying currency symbol in twig

Question

How can I display the currency symbol in twig? I saved the numeric value of the symbol like:

for EURO : &#8364;
for DOLLAR: &#36;

When I render these values, & is converted to & and the currency symbol does not show. Any idea will be greatly appreciated. Thank you.

Have you considered using the utf8 characters instead of the html entities? — Maerlyn, Apr 23 '13 at 16:17
Yes. I've actually considered that. Its just that I've found this easier. Thank you so much for the idea. — Floricel, Apr 24 '13 at 00:06

To do it well, you've to add a function or a filter which is called as a helper to render currency symbols within your twig templates.

To use the following function,

{{ currency('en_US') }}

You've to add a twig extension as follow,

xxx.twig.your_extension:
    class: XXX\YourBundle\Twig\YourExtension
    tags:
        - { name: twig.extension }

You've then to add a currency function,

namespace XXX\YourBundle\Twig;

class YourExtension extends \Twig_Extension
{
    public function getFunctions() {
        return array(
            'currency' => new \Twig_Function_Method($this, 'currencyFunction'),
        );
    }

    public function currencyFunction($locale) {
        $formatter = new \NumberFormatter($locale, \NumberFormatter::CURRENCY);
        $symbol = $formatter->getSymbol(\NumberFormatter::CURRENCY_SYMBOL);

        return $symbol;
    }

    public function getName() {
        return 'your_extension';
    }
}

By the way, I am a little bit confused. What locale should I use for euro symbol? — Floricel, Apr 24 '13 at 00:56
You should then use those related to euro countries (fr-FR / it-IT / ...) — Ahmed Siouani, Apr 29 '13 at 23:44

I figured it out. When rendering, I need to use the raw filter of twig.

Yes, by using raw filter your variable is not escaped. Btw, I added a much cleaner solution that allows you render any currency symbol. – Ahmed Siouani Apr 23 '13 at 14:55

It is an old thread, but for the new people coming here, Twig has now an extension for the currency symbols (with new filters |currency_symbol ) as you can see in the documentation
