php - 多个模型未加载到 codeigniter 中的同一 Controller 中

Question

我想在同一个 Controller 中运行多个模型，但它显示以下错误

Severity: Notice

Message: Undefined property: Home::$Company

Filename: controllers/Home.php

Line Number: 23

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

class Home extends CI_Controller {

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

        $this->load->model('Product');
        $this->load->model('Company');
        //$this->load->model(array('Product','Company'));


    }
    public function index()
    {

        $Product = $this->Product->getProduct(10);
        if($Product)
        {
            $data['Product'] = $Product;
        }
        $Company = $this->Company->getCompany(10);
        if($Company)
        {
            $data['Company'] = $Company;

        }
        $this->load->view('Home',$data);

    }
}

//公司模型

class Company extends CI_Controller {


    function getCompany($limit=null,$start=0)
    {
        $data = array();
        $query = $this->db->query('SELECT * FROM user as u,category as c,sub_category as sc WHERE c.Category_Id=u._Category_Id and u._Sub_Category_Id=sc.Sub_Category_Id ORDER by rand() limit '.$start.','.$limit);
        $res   = $query->result();        
        return $res;
    }
    function getOneCompany($id)
    {
        $this->db->where('User_Id',$id);
        $query = $this->db->get('user');
        $res = $query->result();
        return $res;
    }
}

//产品型号

class Product extends CI_Controller {


    function getProduct($limit=null,$start=0)
    {
        $data = array();
        $query = $this->db->query('SELECT * FROM product as p,user as u,category as c,sub_category as sc WHERE p._User_Id = u.User_Id and  c.Category_Id=u._Category_Id and u._Sub_Category_Id=sc.Sub_Category_Id ORDER by rand() limit '.$start.','.$limit);
        $res   = $query->result();        
        return $res;
    }
    function getOneProduct($id)
    {
        $this->db->where('User_Id',$id);
        $query = $this->db->get('user');
        $res = $query->result();
        return $res;
    }
}

Answer 1

您的模型开头为

class Company extends CI_Controller {

他们应该是

class Company extends CI_Model {

---

<罢工> 尝试改变

$this->load->model('Product');
$this->load->model('Company');

至

$this->load->model('product');
$this->load->model('company');

注意小写的型号名称。刚刚在这里尝试了一下，得到了和你一样的错误。
