CodeIgniter全局变量 [英] CodeIgniter global variable

问题描述

我在所有视图中使用 $ data $ this-> load-> view（'my_view'，$ data）;

I am using $data in all my views $this->load->view('my_view', $data);

我也按照本指南自动加载控制器扩展核心控制器

I have also autoload a Controller following this guide Extending Core Controller

但我想让$ data全局，因为在 views 有一个边栏，它是整个项目的常量，并显示通过自动加载控制器中的db获取的信息

But I want to make $data global because in views there is a sidebar which is constant for whole project and displays info fetched through db in autoloaded controller

目前我必须手动写$ data ['

Currently I have to manually write $data['todo'] for each and fetch info from autoloaded model.

谢谢。

推荐答案

1：使用以下命令在应用程序/ libraries 中创建 MY_Controller / p>

1: Create MY_Controller in application/libraries with following:

class MY_Controller extends Controller {  
  var $data;      
  //constructor function              
}

2：将所有控制器文件中的控制器更改为 MY_Controller ，并使用 $ this- > data

2: Replace Controller to MY_Controller in all your controller files and load views with $this->data

class Contact extends Controller { //to.. } 

class Contact extends MY_Controller { 
 $this->load->view('contact_view', $this->data);
}

适用于整个网站 MY_Controller 喜欢加载设置。

this way you can perform default functions that are applicable for whole site in MY_Controller like loading settings.
