调用非对象上的成员函数setFlash（） [英] Call to a member function setFlash() on a non-object

问题描述

我目前正在学习如何使用CakePHP，我在测试删除功能时遇到了一个错误。以下是错误讯息：

I'm currently learning how to use CakePHP and I encountered a bug while testing the Delete function. Here's the error message:

错误：在非对象

Error: Call to a member function setFlash() on a non-object

File:C:\xampp\htdocs\Forum4Alliances\app\Controller\PostsController.php

行：57

Line: 57

以下代码：

<?php
class PostsController extends AppController{
    public $helpers = array('Html','Form', 'Session');
    public $components = array('Session');

 //Part is omitted...

public function delete($id){
        if($this->request->is('get')){
            throw new MethodNotAllowedException();
        }
        if($this->Post->delete($id)){
            $this->Sessions->setFlash(__('The post with the id: %s has been deleted.', h($id)));
            return $this->redirect(array('action' => 'index'));
        }
    }
}
?>

如你所见，我包含了$ helpers和$ components。

As you see, I included the $helpers and $components. I couldn't find any answers past this point.

推荐答案

您定义：

public $components = array('Session');

但使用比例：

$this->Sessions->setFlash(.. //**SessionS**

更正为：

$this->Session->setFlash
