如何在插件中获取视图对象？

我有一个控制器动作助手,我将用户对象保存到视图中(在init函数中),如下所示:

Zend_Layout::getMvcInstance()->getView()->user = $user;

我想在控制器插件的preDispatch方法中访问该对象,因此我不必在数据库中查找用户.我尝试这样做:

$user = Zend_Layout::getMvcInstance()->getView()->user;

但它返回一个空对象.我希望它,因为我做错了,而不是因为我在我的登录逻辑中编写了一个catch 22.有没有其他方法来访问该对象？

我认为将以下方法放入您的操作助手可能会对您有所帮助.

private $user

public function init()
{
    $this->user = new user();
}

public function preDispatch()
{
    $user = $this->user;
    //Do whatever you wish with the user object.
    // although you probably don't need to do anything.
}

public function direct()
{
    Zend_Layout::getMvcInstance()->getView()->user = $this->user;
    //alternatively just return the user object or whatever you want to do
}
