[英]ZF2 : How to call a view helper in a service?
我需要在此服务中使用视图助手( myPaginationControl ):
/.../
class TotoDisplayService implements ServiceLocatorAwareInterface
{
public function getReponse ($paginator)
{
$tab = '<table>';
/.../
$tab .= myPaginationControl($paginator, 'sliding','pagination_control_file',array('route' => 'paginator'));
/.../
foreach ($paginator as $t) {
//something to list : THIS WORKS
}
$tab .= '</table>';
return array(
'result' => $tab
);
}
/.../
此服务由以下控制器调用:
public function displayAction()
{
$em = $this->getEntityManager();
// query to database
$q1 = $this->serviceLocator->get('toto_list_service');
$rep1 = $q1->getReponse($em);
$paginator = new PaginatorZF(new DoctrinePaginator(new PaginatorORM($rep1)));
$paginator->setCurrentPageNumber ($this->params()->fromRoute('page', 1))->setItemCountPerPage(25);
// prepares something to display with javascript
$q2 = $this->serviceLocator->get('toto_display_service');
$rep2 = $q2->getReponse($paginator);
// return to javascript
return new JsonModel(
$rep2
);
}
这是MyPaginationControl(与paginationControl相同,我做了测试)
use Zend\View\Helper\AbstractHelper;
class MyPaginationControl extends AbstractHelper
{
public function __invoke($a, $b, $c, $d)
{
$PaginationControl = $this->getView()->plugin('paginationcontrol');
return $PaginationControl($a,$b,$c,$d);
}
}
这是module.config.php
'service_manager' => array(
'invokables' => array (
'toto_list_service' => 'Com\Service\Invokable\TotoListService',
'toto_display_service' => 'Com\Service\Invokable\TotoDisplayService'
)
),
'view_helpers' => array(
'invokables' => array(
'myPaginationControl' => 'Com\View\Helper\MyPaginationControl',
),
),
这是module.php(没什么特别的)
class Module implements AutoloaderProviderInterface
{
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . tr_replace('\\', '/' , __NAMESPACE__),
),
),
);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
}
}
在这里错误消息: 调用未定义的函数Com \\ Service \\ Invokable \\ MyPaginationControl()在D:\\ Zend \\ Apache2 \\ htdocs \\ Gestion \\ module \\ Com \\ src \\ Com \\ Service \\ Invokable \\ TotoDisplayService.php
并且此控制器由javascript(AJAX)调用。 当我注释以下行时,所有工作正常: $ tab。= myPaginationControl(...
我验证了在phtml文件中使用它时,视图助手myPaginationControl可以正常工作。
预先感谢您的帮助。
在您的控制器中执行以下操作:
$this->getServiceLocator()->get('ViewHelperManager')->get("toto_display_service")
请,这不是最好的解决方案。 相反,我建议您通过__constructor(){}将viewhelper与工厂一起传递
namespace Application\Factory\Controller;
use Application\Controller\MyClassNameController;
use Zend\Mvc\Controller\ControllerManager;
class MyCLassNameFactory
{
/**
* @{inheritDoc}
*/
public function __invoke(ControllerManager $controllerManager)
{
$serviceLocator = $controllerManager->getServiceLocator();
$controller = new MyClassNameController(
$serviceLocator->get('ViewHelperManager')->get('toto_display_service');
);
return $controller;
}
}
并在MyClassController中
class MyClassNameController extends ADD_ANOTHER_CONTROLLER
{
private $todoService = null;
public function __construct($todoService = null)
{
$this->todoService = $todoService
}
}
之后,在Module.php或module.config.php中添加配置。 我更喜欢module.config.php文件。
'controllers' => [
'factories' => [
'Application\Controller\MyClassName' => 'Application\Factory\Controller\MyClassNameFactory'
],
],
不要忘记从发票中删除控制器,否则它将无法正常工作,并且会发生碰撞
$tab .= myPaginationControl
应该是$tab .= new myPaginationControl
或$tab .= $this->myPaginationControl
如果上述方法无效,请转储$this->getServiceLocator()->get('ViewHelperManager')
找到myPaginationControl
并像这样调用它$this->getServiceLocator()->get('ViewHelperManager')->get("myPaginationControl");
