Question

我想在同一个控制器中运行多个模型，但它显示在错误

之下

严重性：注意

消息：未定义属性：主页:: $ Company

文件名：controllers / Home.php

行号：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);

    }
}

//公司模式

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

$models = array(
    'menu_model' => 'mmodel',
    'user_model' => 'umodel',
    'admin_model' => 'amodel',
);
foreach ($models as $file => $object_name)
{
    $this->load->model($file, $object_name);
}

Answer 2

您的模型以

开头

class Company extends CI_Controller {

他们应该

class Company extends CI_Model {

<击> 尝试更改

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

到

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

~~注意小写的模型名称。只是在这里试了一下，得到了和你一样的错误。~~

Answer 3

尝试为您的模特命名：

addMibCompiler(mibBuilder, sources=['http://mibs.snmplabs.com/asn1/@mib@'], destination='/home/krish/mibs')

多个模型未在codeigniter
