CodeIgniter无法从控制器中的模型调用函数 [英] CodeIgniter can't call function from model in controller

问题描述

我对Codeigniter相当陌生，正尝试从模型中调用一个函数，但无法使其正常工作。有人能看到我在这里做错了吗？

I am fairly new to Codeigniter and am trying to call in a function from my model but I cannot get it to work. Can anyone see what I am doing wrong here?

控制器（farm.php）：

Controller (farm.php):

<?php defined('BASEPATH') OR exit('No direct script access allowed');

    class Farm extends CI_Controller {

        function __construct()
        {
            parent::__construct();
            $this->load->model('harvest_first');
        }

        function harvest()
        {

            echo $this->harvest_first->harvest();
        }   
    }

模型（harvest_first.php）：

Model (harvest_first.php):

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class Harvest_first extends CI_Model
    {

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

        public function harvest(){
            return "THE FUNCTION";
        }
    }
?>

我正试图呼应功能，但无论如何我都无法理解

I am trying to echo "THE FUNCTION", but no matter what I do I cannot get it to work as expected.

谢谢，
Simon

Thanks, Simon

推荐答案

尝试一下

class Harvest_first extends CI_Model

更改为：

class Harvest_first_model extends CI_Model

，并在控制器调用中像这样：

and in controller call like this:

 $this->load->model('harvest_first_model');

和

 $this->harvest_first_model->harvest();
