Question

I remember in symfony 1.x there was a "currency" field type, which was a select with all currencies in the world. Is there something like this in symfony2?

Answer 1

I couldn’t find one, so I created one myself. I got the list from here

This is a class for containing all the currencies

namespace Gilden\Bundle\InvoiceBundle\Form\Extension\ChoiceList;

use Symfony\Component\Form\Extension\Core\ChoiceList\ChoiceListInterface;

/**
 * Choice list for ISO currencies found on http://www.xe.com/iso4217.php
 */
class CurrencyChoiceList implements ChoiceListInterface
{
    public function getChoices()
    {
        return array(
            'AED' => 'AED',    'AFN' => 'AFN',    'ALL' => 'ALL',

            'ZMK' => 'ZMK',    'ZWD' => 'ZWD',
        );
    }
}

This is the actual form type

namespace Gilden\Bundle\InvoiceBundle\Form\Extension\Type;

use Gilden\Bundle\InvoiceBundle\Form\Extension\ChoiceList\CurrencyChoiceList;
use Symfony\Component\Form\AbstractType;

class CurrencyType extends AbstractType
{
    /**
     * {@inheritDoc}
     */
    public function getDefaultOptions(array $options)
    {
        return array(
            'choice_list'       => new CurrencyChoiceList(),
            'preferred_choices' => array('EUR', 'USD', 'RUB', 'LVL', 'LTL')
        );
    }

    /**
     * {@inheritDoc}
     */
    public function getParent(array $options)
    {
        return 'choice';
    }

    /**
     * {@inheritDoc}
     */
    public function getName()
    {
        return 'currency';
    }
}

I hope this helps.
