如何在所有控制器中集中来自我的 init 函数的代码? [英] How do I centralize code from my init functions in all controllers?

问题描述

public function init(){
        $this->view->user = Zend_Auth::getInstance()->getIdentity();
        $this->view->siteName = Zend_Registry::get('config')->site->name;
        $this->view->menu = $this->_helper->generateMenu(Zend_Auth::getInstance()->getIdentity());
        $this->view->slogan = Zend_Registry::get('config')->site->slogan;
    }

这是我所有模块中所有控制器中的 init 文件，有没有地方可以放置此代码，以便它执行每个请求，而不管模块/控制器是否被调用?

This is the init file in all of my controllers across all modules, is there a place I can put this code so it executes every request irregardless of the module/controller being called?

推荐答案

你可以扩展 Zend_Controller_Action:

You can extend Zend_Controller_Action:

public class My_Controller_Action extends Zend_Controller_Action
{
    public function init()
    {
        $this->view->user = Zend_Auth::getInstance()->getIdentity();
        $this->view->siteName = Zend_Registry::get('config')->site->name;
        $this->view->menu = $this->_helper->generateMenu(Zend_Auth::getInstance()->getIdentity());
        $this->view->slogan = Zend_Registry::get('config')->site->slogan;
    }

}

然后您只需更改控制器以扩展 My_Controller_Action 而不是 Zend_Controller_Action.请记住，如果您需要向控制器的 init 方法添加其他代码，则还必须调用 parent::init():

Then you just change your controllers to extend My_Controller_Action rather than Zend_Controller_Action. Just keep in mind that if you need to add additional code to the init method of a controller, you'll have to invoke parent::init() as well:

public class FooController extends My_Controller_Action
{
    public function init()
    {
        parent::init();

        // Do something.
    }

    public function IndexAction()
    {
        // ...
    }
}
