Currencies within the view
- Posted by thomasw at 22:12:52 // //
- Announcements, Currency
Today the last missing sheep of my new Zend_Currency implementation has been moved to core.
It’s the view helper for currencies which was missing.
Zend_View_Helper_Currency
Together with the new Zend_Currency implementation it simplifies rendering for all using currencies within their application. Let’s take a short look into an working example…
// Bootstrap
$currency = new Zend_Currency(array('value' => 100, 'locale' => 'fr_FR'));
Zend_Registry::set('Zend_Currency', $currency);
We prepared our currency to be used application wide.
Now the view:
// View $this->currency();
This would output “100,00 €” (or something related).
Really simple, isn’t it ?
Of course this would not work when you have multiple currencies which you are working with.
Then you must work with other registry keys and give the wished instance.
// Model
$instance_1 = new Zend_Currency(array('value' => 100, 'locale' => 'fr_FR'));
$instance_2 = new Zend_Currency(array('value' => 500, 'locale' => 'en_US'));
And in the view:
// View $this->currency($instance_1); $this->currency($instance_2);
Please look into the manual for further informations.
There’s nothing more to say than enjoy my new currency implementation for Zend Framework. ;-)

I’m a bit confused in the usage of this new view helper. For example, it is a common task, that you iterate over a products-array in the view and you want to show the currency values. Is it possible to do the following?
// Zend_Application resource
$currency = new Zend_Currency(array(’locale’ => ‘de_DE’));
Zend_Registry::set(’Zend_Currency’, $currency);
// View
foreach($products as $product)
{
echo $produuct[’name’] . ‘ - ‘ . $this->currency($product[’price’]) . ‘<br />’;
}

Why are you confused?
Take a look into the manual… the following example is given within there:
// our example currency
$currency = new Zend_Currency(’de_AT’);
// initiate the helper
$helper = new Zend_View_Helper_Currency($currency);
echo $helper->currency(1234.56); // this returns ‘€ 1.234,56′
echo $helper->currency(1234.56, array(’precision’ => 1));
// this returns ‘€ 1.234,6′
As you can see it IS possible and even documented.
Still this is no way I would propose to use as it adds logic to the view itself. You should probably take a look into Zend_Layout and the View Partitials to come to a better solution for you regarding code in the view. :-)

I haven’t seen it in the reference guide on the framework website, that’s why I asked for that. This way will help to prevent looping an array twice in controller (or model) for modifying the currency value output and in view for presentation.
This is a great improvement!

When you want to use a component from trunk than you must also look into the manual from trunk.
Website points always to the last official release.

$currency = new Zend_Currency(’pt_BR’);
//$currency = new Zend_Currency(’INR’);
echo $currency->getSymbol();
Indian Currency has got a new symbol i think we need to implement that

Currency signs are part of CLDR. Look to unicode (http://cldr.unicode.org) and open an issue at CLDR when you see problems in their data.
