错误消息：调用未定义的方法 CI_DB_mysqli_result::results()

Question

我是 CodeIgniter 的新手，在连接 db 后遇到以下错误。如果有人可以帮助我，那真是太好了。我检查了 StackOverflow 中以前的答案，但没有一个对我有帮助。

下面是控制器代码

    <?php

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

class Welcome extends MY_Controller {

    public function index() {

        $this->load->view('home');

    }

    public function adminRegister() {

        //loading teh queries model 

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

        //Calling the getRoles function inside the roles

        $roles = $this->queries->getRoles();

        print_r($roles);

        exit();

        $this->load->view('register');

    }

    public function login() {

        echo 'login';

    }

}

型号代码

    <?php

//Details of queries whicha re used to interact with teh database

class Queries extends CI_Model {

//Created a function with the name getRoles  

    public function getRoles() {

        //Fetch the reocrds from the table

        $roles = $this->db->get('tbl_roles');

        if ($roles->num_rows() > 0) {

            return $roles->results();

        }

    }

}

?>

目前不使用来自控制器的数据。任何帮助将不胜感激。提前致谢。

没有结果应该是结果参考CI 文档class Queries extends CI_Model {&nbsp; &nbsp; //Created a function with the name getRoles&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; public function getRoles() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //Fetch the reocrds from the table&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $roles = $this->db->get('tbl_roles');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if ($roles->num_rows() > 0) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return $roles->result();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }
