如何在cakePHP中显示会话变量

Question

我有一个控制器类，在其下面添加一个学生进入会话。

class StudentsController extends AppController var $ name =“Student”;

function addstudent() 
    { 
     //$id=$_REQUEST['id']; 
     //$this->Session->write('id', $id); 
     static $count=0; 
     if (!empty($this->data)) { 

     $students = $this->Session->read('Student'); 
     if (!$students) { 
      $students = array(); 


     } 
     $students[] = $this->data['Student'];/* data */ 
     $this->Session->write('Student', $students); 
     $this->Session->write('student_count',$count); 
      $this->redirect(array('controller'=>'students','action' => 'addstudent')); 
     }  

    } 
} 

我的问题是如何显示的所有视图page.please增加的学生给我解释一下语法

Answer 1

会话助手添加到您的视图。代码访问STUDENT_COUNT变量将

$session->read('student_count'); 

一般语法

$session->read('var_name'); 

Answer 2

$student_list = $this->Session->write('Student', $students); 
$student_count = $this->Session->write('student_count',$count); 

$this->set('$student_list',student_list); 
$this->set('$student_count',student_count); 

使用student_list和STUDENT_COUNT在视图页面。
