Hi,
in a discussion an issue came up regarding good or bad practice for ZF2
view helpers.
Is it good or bad practice to inject other objects, especially model
services, into a view helper to call methods to get some data fetched?
For example within the __invoke() method I could get the data from a
service like this:
------------------------------------------------------------------------
namespace Pizza\View\Helper;
use Zend\Form\View\Helper\AbstractHelper;
use Pizza\Service\PizzaService;
class RandomPizza extends AbstractHelper
{
protected $service = null;
public function __construct(PizzaService $service)
{
$this->setPizzaService($service);
}
public function setPizzaService(PizzaService $service)
{
$this->service = $service;
}
public function getPizzaService()
{
return $this->service;
}
public function __invoke()
{
$random = $this->getPizzaService()->fetchSingleByRandom();
$html = '<div class="hero-unit">';
$html.= '<h1>' . current($random) . '</h1>';
$html.= '</div>';
return $html;
}
}
------------------------------------------------------------------------
Would you say this view helper is an example for good or for bad practice?
Thanks for your comments.
Regards,
Ralf
