扩展CI的控制器

发布时间：2020-01-23 12:19:08编辑：雪饮阅读（）

在application/core中建立My_Controller.php

<?php
 class My_Controller extends CI_Controller{
     public function __construct()
     {
         parent::__construct();
         echo "dmj";
     }
 }

然后随便找一个控制器就可以继承上面的控制器了

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 
 class Welcome extends My_Controller {
 
    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *        http://example.com/index.php/welcome
     * - or -  
     *        http://example.com/index.php/welcome/index
     * - or -
     * Since this controller is set as the default controller in 
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $res=$this->db->where("name","dmj")->get("blog_user");
         $res=$this->db->where(["name"=>"dmj"])->get("blog_user");
         $res=$this->db->where(["name"=>"dmj","id >"=>2])->get("blog_user");
       var_dump($res->result());
    }
 }
 
 /* End of file welcome.php */
 /* Location: ./application/controllers/welcome.php */

 

这就是ci扩展控制器的方法，当然控制器前缀可以不固定为“My”默认为“My”，在配置文件application/config/config.php中：

$config['subclass_prefix'] = 'MY_';
