Yii 1.1：跨控制器变量（甚至是交叉控制变量）

Question

For each request I have to load or, at least, create instance of a MyUser, which contains username, some internal permissions info, link to avatar and so on.

The thing is that I need this info for each and every controller and, for most of the views (to render or not to render some controls depending on user status and permissions).

It sounds like the need for a global variable, created at the time request being handled. What is the best way to solve this problem?

Override CWebUser (which is what you call when you issue Yii::app()->user) with your custom class WebUser (placed in the components or other folder that has it's classes autoincluded), and define some getters like it is done with getRole() example below:

<?php
class WebUser extends CWebUser {
    private $_model = null;
    function getRole() {
        if($user = $this->getModel()){
          return $user->userRole->name;
        }
    }
    private function getModel(){
        if (!$this->isGuest && $this->_model === null){
          $this->_model = User::model()->findByPk($this->id);
        }
        return $this->_model;
    }   
}

If you user the custom class instead of CWebUser, you have to explicitly tell which class to use in application's config:

'user'=>array(
    'class' => 'WebUser',
    // …
),
