Question

我想问一下，如果在codeigniter中扩展控制器的正确方法是什么。因为我现在遇到Fatal error: Class 'ApiController' not found in两个文件都驻留在同一目录api文件夹中。这是我的代码：

<?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

在扩展之前，您需要包含基类文件。

<?php
//EchelonApiController.php

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

class EchelonApiController extends ApiController {

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

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

如果 ApiController.php 和 EchelonApiController.php 都在同一个文件中，可以直接使用

require "ApiController.php";

否则只需在 APPPATH 常量的帮助下添加正确的路径。

Answer 2

也许这可能对你有所帮助。 Extending The Controller Class in CodeIgniter

这似乎是类似的情况，也许文件放置是您问题的一部分。

Answer 3

将您的ApiController放在application / core目录中。

类欢迎扩展CI_Controller {

function __construct()
{
    parent::__construct();
    $this->load->database();
    $this->load->model("User_model");
    $this->load->helper("form");
    $this->load->helper("url");
}
/**
 * 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 https://codeigniter.com/user_guide/general/urls.html
