Cakephp redirect对null上的成员函数header（）进行错误调用

//获奖者控制者

在permissioncontroller中，echo正在打印，但url的重拨会产生致命错误：调用null上的成员函数header（）。任何建议

我想出了窍门。 //获奖者控制者

App::import('Controller', 'Permissions');
        class AwardsController extends AppController {
        public function add($id=NULL) {
            if (!$id) {
                throw new NotFoundException(__('Invalid User'));
            }
            if(!$this->Session->check('Auth.User')){
                $this->redirect(array('controller'=>'users','action' => 'login'));      
            }else{
                $Permission= new PermissionsController;
                if($Permission->isAuth($id)){
                    if ($this->request->is('post')) {
                        $this->Award->create();
                        $this->request->data['Award'][0]['basicprofile_id']=10;
                        var_dump($this->data);
                        if ($this->Award->saveAll($this->request->data['Award'])) {
                            $this->Session->setFlash(__('Award has been added '));
                            //$Permission= new PermissionsController;
                            //$this->redirect(array('controller'=>'users','action' => 'login'));
                            $this->redirect($Permission->redirectProfile($id));
                        } else {
                            $this->set('error',sizeof($this->request->data['Award']));
                            $this->Session->setFlash(__('The award has not added. Please, try again.'));
                        }   
                    }
                }else{
                    $this->Session->setFlash(__('You are not authorized to access it'));
                    $this->redirect(array('controller'=>'users','action' => 'login'));
                }
            }
        }
    }

只需返回url地址进行重定向，并从awardscontroller本身重定向它。

它是否打印“正在工作”？是的，如果$this->redirect（数组（'controller'=>'users'，'action'=>'index'），它的打印工作正常；请告诉我们，如果您将

if（AuthComponent:：user（'role'）=='Admin'）{echo“正在工作”；$this->redirect（数组（'controller'=>'users'，'action'=>'index'））；}放入其他if（AuthComponent:：user（'role'）=='Teacher'）{/$this->redirect（数组（'controller'=>'profiles'，'action'=>'Teacher'，$id））会发生什么；}

code而不是

$Permission->redirectProfile（$id）？我的意思是在当前控制器函数本身中替换它。简言之，您必须调用函数，而不是再次编写相同的代码。简单和简短：）正确吗？我想这是cakephp的问题。因此，只需返回要重定向的url地址，并从awardscontroller本身重定向它即可。：）。
