模型文件

<?php

     public function __construct() 
     {
           parent::__construct(); 
           $this->load->database();
           $this->load->library('session');

     }

    function get_div(){
        $this->db->select("*");
        $this->db->from('vefm_comp_division');
        $query = $this->db->get();
        $result = $query->result();
        print_r($result);
        return $result;
    }

    function get_customer(){
        $this->db->select("*");
        $this->db->from('vefm_client_details');
        $query = $this->db->get();
        $result = $query->result();

        return $result;
    }


}

在访问模态函数之前初始化模态

public function index()
{
        if (!$this->session->userdata('login_data')) {
            redirect('Login');
        }else{
            $this->load->model("Timesheet_modal");
            $datas['division'] = $this->Timesheet_modal->get_div();
            $datas['customer'] = $this->Timesheet_modal->get_customer();
            print_r($datas);
            $this->load->view('user/timesheet_add', $datas);
        } 
     }
