我认为您犯了2个错误

1. 忘记将结果提取到数组


2. 忘记将数据传递给视图

更改模型类。

public function get_users(){

    $data = array();
    $query = $this->db->get('users');
    $res   = $query->result();        
    return $res;

 }

更改控制器类

public function index() {

    $this->load->view('template/header');

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

    $this->load->view('template/footer');

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

    $res = $this->manage_accounts_model->get_users();

    if($res){
        $data['result'] = $res;
        $this->load->view('manage_accounts_view', $data);

    } else {

        echo "Fail";

    }

您认为

  print_r($result);
