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

Your models start with

class Company extends CI_Controller {

They should be

class Company extends CI_Model {

---

Try changing

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

to

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

notice the lower case model names. Just tried it here and got the same error as you.

Answer 3

尝试为您的模型命名：

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