在我的 CakePHP 应用程序中,当我使用另一个控制器的类时,我得到 Session read function 错误。
example.com/app/getList
运作良好
example.com/seconds/parseList
运作良好
但example.com/first/index
给出了这个错误:
Fatal error: Call to a member function read() on a non-object in
/example.com/app/Controller/AppController.php on line 468
第 468 行是这样的:$list=$this->Session->read('myList');
我怎样才能解决这个问题 ?
class FirstController extends AppController {
public function index () {
$Seconds = new SecondsController();
$Seconds->parseList();
}
}
class SecondsController extends AppController {
public $helpers = array('Html', 'Session');
public function parseList () {
$output = $this->getList();
return output;
}
}
class AppController extends Controller {
public $uses = array('App', 'Mydata');
var $components = array('Session');
public $helpers = array('Session','Html','Cache');
public function getList () {
$list=$this->Session->read('myList');
return $list;
}
}
编辑:我应该提到example.com/app/getList
效果很好。当我独立运行此操作时,它不会给出会话错误。
