Question

我在Module.php的引导程序中创建了一个全局变量

public function setCashServiceToView($event) {

    $app = $event->getParam('application');
    $cashService = $app->getServiceManager()->get('Calculator/Service/CashServiceInterface');
    $viewModel = $event->getViewModel();
    $viewModel->setVariables(array(
        'cashService' => $cashService,
    ));
}
public function onBootstrap($e) {

    $app = $e->getParam('application');
    $app->getEventManager()->attach(\Zend\Mvc\MvcEvent::EVENT_RENDER, array($this, 'setCashServiceToView'), 100);
}

我可以在layout.phtml中使用它作为

$this->cashService;

但是我需要在我的部分导航菜单脚本中使用这个变量，我在layout.phtml中调用它：

      echo $this->navigation('navigation')
          ->menu()->setPartial('partial/menu')
          ->render();
  ?>

如何在partial / menu.phtml中使用它？也许有更好的方法，而不是在onBootstrap函数中声明它？

感谢您的回答。我决定制作一个扩展类的\ Zend \ View \ Helper \ Navigation \ Menu来提供cashService的属性。但是我收到一个错误：'Zend \ View \ Helper \ Navigation \ PluginManager :: get无法获取或创建Calculator \ Service \ CashServiceInterface的实例'。我需要这项服务才能显示导航菜单。看起来很奇怪，但那是真的。我使用从服务中获得的数据在其中显示一些图表。那我为什么会有这个错误呢？我添加到module.config.php

    'navigation_helpers' => array(
    'factories' => array(
        'mainMenu' => 'Calculator\View\Helper\Factory\MainMenuFactory'
    ),

MainMenuFactory：

namespace Calculator\View\Helper\Factory;

use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Calculator\View\Helper\Model\MainMenu;

Class MainMenuFactory implements FactoryInterface {

    /**
    * Create service
    *
    * @param ServiceLocatorInterface $serviceLocator
    * @return mixed
    */
    public function createService(ServiceLocatorInterface $serviceLocator) {

        return new MainMenu(
            $serviceLocator->get('Calculator\Service\CashServiceInterface')
        );
    }

P.S：CashServiceInterface是CashServiceFactory的别名

You could remove the event listener and use a custom view helper to access the service in the view.

namespace Calculator\View\Helper;

use Zend\View\Helper\AbstractHelper;

class CashService extends AbstractHelper
{
    protected $cashService;

    public function __construct(CashServiceInterface $cashService)
    {
        $this->cashService = $cashService;
    }

    public function __invoke()
    {
        return $this->cashService;
    }
}

Create a factory.

namespace Calculator\View\Helper; 

class CashServiceFactory
{
    public function __invoke($viewPluginManager)
    {
        $serviceManager = $viewPluginManager->getServiceLocator();
        $cashService    = $serviceManager->get('Calculator\\Service\\CashServiceInterface');

        return new CashService($cashService);
    }
}

Register the new helper in moudle.config.php.

'view_helpers' => [
    'factories' => [
        'CashService' => 'Calculator\View\Helper\CashServiceFactory',
    ],
],

Then you can use the plugin in all view scripts.

$cashService = $this->cashService();

如何将变量传递给zf2中的部分导航脚本？
