在调度事件上访问 ViewModel 变量 [英] Access ViewModel variables on dispatch event

问题描述

这是一个 ZF2 问题.

This is a ZF2 question.

我正在尝试更改我的模板，具体取决于我的控制器上设置的变量(因为我将决定使用哪个模板).在我的 onBooststrap 模块中，我有:

I'm trying to change my template, depending on a variable setted on my controller (since is there that im going to decide which template use). In my module onBooststrap i have:

$this->eventManager->attach('dispatch', function($e)
    {
        if (0 === strpos($e->getRouteMatch()->getParam('controller'), __NAMESPACE__, 0))
        {
            $e->getViewModel()->setTemplate('layout');
        }

    }, -100);

在我的控制器中:

class IndexController extends AbstractActionController
{
    public function indexAction ()
    {
        $view = new \Zend\View\Model\ViewModel();
        $view->setVariable("layout", "layout");
        return $view;
    }
}

但是，我如何访问该视图变量布局"，以便我可以在 setTemplate 的调度事件中更改它?

but, how do i get access to that view variable "layout", so i can change it in the dispatch event on setTemplate?

推荐答案

查看 onDispatch 方法和 MvcEvent 类似乎有一个 getResult() 方法，这可能包含控制器操作的结果.

Looking at the onDispatch method and the MvcEvent class it seems there is a getResult() method, this may contain the result from the controller action.

否则你有没有看过布局控制器插件?此插件将允许您更改模板:

Otherwise have you looked at the layout controller plugin? This plugin would allow you to change the template:

$this->layout('new layout');

当然，这需要在控制器内部，而且很可能需要将模板添加到模板映射中.

Of course this would need to be inside the controller and most likely require adding the template into the template map.
