yii2 - how to set currency decimal value

Question

I want my currency to ignore decimal value, so far I have this:

main.php:

'formatter' => [
   'class' => 'yii\i18n\Formatter',
   'thousandSeparator' => '.',
   'decimalSeparator' => ',',
   'currencyCode' => '€',

],

view:

[
   'attribute' => 'Score',
   'format' => 'currency',
],

Any idea on how to move forward?

Answer 1

The manual on currencyCode:

The 3-letter ISO 4217 currency code indicating the default currency to use

Try setting currencyCode to 'EUR' (though that doesn't seem to be that important) and put the formatter in an array

[
   'attribute' => 'Score',
   'format' => [
       'currency',
       'EUR',
       [
           \NumberFormatter::MIN_FRACTION_DIGITS => 0,
           \NumberFormatter::MAX_FRACTION_DIGITS => 0,
       ]
    ],
],

This requires the PHP intl extension to be installed. Status of the extension can be tested by calling extension_loaded('intl'). In absence of the extension, your best bet is probably to write a custom formatter.

<?php
namespace app\components;

class Formatter extends \yii\i18n\Formatter
{
    public function asRoundedCurrency($value, $currency)
    {
        return $this->asInteger(round($value)) . ' ' . $currency;
    }
}

Use it instead of the default formatter an then call it like this:

[
    'attribute' => 'Score',
    'format' => ['roundedCurrency', 'EUR'],
]

This also allows you to freely set the currency symbol.
