在另一个 ViewHelper 中创建 Url View Helper 的实例 [英] Create an instance of Url View Helper in another ViewHelper

问题描述

在我的项目中，我创建了一个 Helper 来显示 a-tags，但如果用户具有 ACL 权限，还需要额外检查.当他可以访问 url 时，我想使用现有的 UrlHelper 创建 Url - 但我无法实例化它:

In my project i created a Helper to display a-tags, but with an additonal check, if the user has ACL rights. When he has access to the url, i want to create the Url with the existing UrlHelper - but i can't instantiate it:

// try 1
$pluginHelper = \Zend\Mvc\Service\ViewHelperManagerFactory::createService($this->getServiceLocator());
$this->_urlHelper = $pluginHelper->get('url');

// try 2
$factory = new \Zend\Mvc\Service\RouterFactory();
$router = $this->_urlHelper = $factory->createService($this->getServiceLocator());

// try 3
$module = new \RDGOnline\Module();
$config = $module->getConfig();
$router = \Zend\Mvc\Router\Http\TreeRouteStack::factory($config['router']);

$this->_urlHelper = new Url();
$this->_urlHelper->setRouter($router);

我尝试了不同的方法，但都失败了.在我最后一次尝试中，创建了 url - 但它忽略了子文件夹.IE./主干/

I attempted different ways, but all failed. In my last try the url was created - but it ignores the subfolder. I.E. /trunk/

感谢您的帮助.

推荐答案

如果你在一个视图助手中这样做，你可以通过注入视图的插件方法访问视图助手(插件)

If you're doing this inside a view helper, you can access view helpers (plugins) through the injected view's plugin method

public function someViewHelperMethod()
{
    $urlHelper = $this->view->plugin('url');
}
