在Codeigniter 2.0中扩展控制器

Question

I would like to ask, if what is the proper way of extending a controller in codeigniter. Because right now I am encountering a Fatal error: Class 'ApiController' not found in both files resides on the same directory api folder. Here's my code:

<?php
//EchelonApiController.php
class EchelonApiController extends ApiController {

    public function __construct() {
       parent::__construct();
    }

    public function index(){
        echo 'asd';
    }
}


<?php
// ApiController.php
class ApiController extends CI_Controller {

    public $table;

    public function __construct(){

        parent::__construct();

        $this->load->models("api/".$table);
    }

    public function index(){

    }
}

Answer 1

You need to include the Base Class file before extending it .

<?php
//EchelonApiController.php

require "path/to/file/ApiController.php";

class EchelonApiController extends ApiController {

    public function __construct() {
       parent::__construct();
    }

    public function index(){
       echo 'asd';
    }
}

if ApiController.php and EchelonApiController.php both are in same file , you can directly use

require "ApiController.php";

otherwise just add correct path with the help of APPPATH constant.
