Cakephp致命错误：在非对象上调用成员函数format（）

问题描述

我正在开发Cakephp 2.3 ..这是我的代码

i am working on a Cakephp 2.3 .. here is my code

  class MessagesController extends AppController{
     public $helpers = array('Time');

    public function messages(){

    $datetime=  $this->Message->getDatetime($userid); //$datetime = 2013-06-14 10:28:00



    $time = $this->Userinfo->getTimeZone($userid);   //$time = 5.00

   $finaltime =   $this->Time->format('Y-m-d H:i:s', $dateTime, NULL, $time);

exit（）;

}

它给了我

Fatal error: Call to a member function format() on a non-object

$上调用成员函数format（） b
$ b

有人知道我在做什么错吗？

anybody know what i am doing wrong?

推荐答案

问题是，仅仅因为您在控制器中使用$ helper并不意味着它可以访问。它实际上正在传递给视图或.ctp文件。

The problem is that just because you are using the $helper in the controller doesn't mean it is accessible. It is actually geting passed to the view or .ctp file.

// called as CakeTime
App::uses('CakeTime', 'Utility');
echo CakeTime::format('2011-08-22', '%d-%m-%Y');
