Question

我有功能，它可以提高教师的平均费率，并保存变量$result的平均值我希望将变量传递给get_teacher_average_rating并打印平均值，但我尝试这样做我有错误

注意（8）：未定义的变量：结果 [APP / Controller / RatingSchoolsController.php，第30行]警告（2）：无法修改标头信息 - 已经发送的标头（输出开始于 /Applications/MAMP/htdocs/classera-core-code/lib/Cake/Utility/Debugger.php:795） [APP / Controller / AppController.php，第67行]

如何在get_teacher_average_rating

中修复此问题并打印平均值

public function set_teacher_average_rating($result)
    {
        $this->autoRender = false;
        if($this->request->is('get'))
        {
            $author_id = $this->request->query('author_id');//
            $rate = $this->Rating->find('all',array('conditions'=>array('author_id'=> $author_id), 'fields'=> array('AVG(Rating.value) as averageRating'), 'recursive' =>-1));

            $average = $rate[0][0]['averageRating'];
            $result = array('success'=>'1' , 'average' => $average );
        }
        else{
            $result = array('success'=>'0','message'=>'request type is not GET');
        }
        echo json_encode($result);
    }


public function get_teacher_average_rating()
    {
        $this->autoRender = false;
                $average = $this->set_teacher_average_rating($result);
                $rate = $this->Rating->find('all',array('conditions'=>array('author_id'=> $author_id)));

                     //get rate teacher
                                echo json_encode($average);



        }

如果任何其他函数没有调用函数set_teacher_average_rating（），请尝试此操作：

public function set_teacher_average_rating()
    {
        $this->autoRender = false;
        if($this->request->is('get'))
        {
            $author_id = $this->request->query('author_id');//
            $rate = $this->Rating->find('all',array('conditions'=>array('author_id'=> $author_id), 'fields'=> array('AVG(Rating.value) as averageRating'), 'recursive' =>-1));

            $average = $rate[0][0]['averageRating'];
            $result = array('success'=>'1' , 'average' => $average );
        }
        else{
            $result = array('success'=>'0','message'=>'request type is not GET');
        }
        return $result;
    }


public function get_teacher_average_rating()
    {
        $this->autoRender = false;
                $average = $this->set_teacher_average_rating();
                $rate = $this->Rating->find('all',array('conditions'=>array('author_id'=> $author_id)));

                     //get rate teacher
                                echo json_encode($average);



        }
