CodeIgniter在同一个控制器中加载多个模型

Question

这些是控制器

class Dashboard extends CI_Controller{
public function __construct(){
    parent::__construct();
    $this->load->model("admin/post_model");
    $this->load->model("admin/comment_model");
}
    public function index(){
    $data['post_res'] = $this->post_model->getPost();
    $data['com_res']  = $this->post_model->getComments();
    }
 }

我无法在同一个控制器中加载2个模型.它给了我一个错误

Fatal error: Call to a member function getComments() on a non-object in C:\xampp\htdocs\blog\application\controllers\ram-admin\dashboard.php on line 13

我怎么可能加载模型？

非常感谢你!

Answer 1

试试这个

class Dashboard extends CI_Controller {
 function __construct() {
      parent::__construct(); 

    $this->load->model("admin/post_model","post_model");
    $this->load->model("admin/comment_model","comment_model");
  }

public function index(){

    $data['post_res'] = $this->post_model->getPost();
    $data['com_res']  = $this->comment_model->getComments();
}

Answer 2

getComments( ) 是comment_model，而不是 post_model ..

您可以通过传递第二个参数来命名模型；

$this->load->model('admin/comment_model', 'comments');
$data['com_res'] = $this->comments->getComments();
