在 View 中使用 Zend_Acl 来显示/隐藏部分视图的方法是什么 [英] Whats the way to use Zend_Acl in View to show/hide parts of view

问题描述

我想知道使用 Zend_Acl 显示/隐藏部分视图的方法是什么?我想我会

I am wondering whats the way to use Zend_Acl to show/hide parts of view? I am thinking I will

1. 创建一个Controller Plugin，通过登录用户+ acl查看

1. Create a Controller Plugin that passes the logged in user + acl to view

 $this->view->loggedInUser = Zend_Auth::getIdentity();
 $this->view->acl = Zend_Registry::get('acl');

然后在视图脚本中执行类似

Then in view scripts do something like

$this->acl->isAllowed($this->view->loggedInUser, 'resource', 'privilege');

或者有更好的方法吗?还是应该使用视图助手?返回一个布尔值是否允许登录用户?

Or is there a better way? Or should I use a View Helper? That returns a boolean whether the logged in user is allowed?

推荐答案

你在视图中使用它，所以对我来说 ViewHelper 是正确的地方 - 我已经这样做过一次:

You are using it in the view, so for me ViewHelper is correct place for that - I've done it once that way:

class Zend_View_Helper_HasAccess extends Zend_View_Helper_Abstract
{
    private $_acl;
    public function hasAccess($role, $controller, $action)
    {
        if (!$this->_acl) {
            $this->_acl = Zend_Controller_Front::getInstance()->getPlugin('Acl'); 
            //In yout case registry, but front controller plugin is better way to implement ACL
        }
        return $this->_acl->isAllowed($role, $controller, $action);
    }
}
