如何使非codeigniter文件夹/文件中的加载codeigniter数据库库？

Question

i have a folder named superfunctions

that folder is in same level with the controller, model and views folder

is it possible to call the the database library inside the php files of that said folder.

I want to use this->db->query("") etc...

on or inside

application/superfunctions/function1.php

function1.php is just pure function / not a class

Answer 1

The proper way to achieve your goal is to make it a helper file.

/application/helpers/function1.php

function1.php

<?php
if(!function_exists('function1'))
{
    function function1()
    {
        // Get the CodeIgniter instance by reference
        // Basically, $this from the controller is now $CI within this function
        $CI = &get_instance();

        $CI->db->query("");
        // do whatever

        return 'hi';
    }
}

So whenever you need it in your controller then just do:

class Welcome extends CI_controller {

    public function __construct()
    {
        $this->load->helper('function1');
    }

    public function index()
    {
        echo function1();
    }
}

Answer 2

why not create a library with those functions, and autoload that library On the other hand, you can create a class in you sub folder like

<?php
class My_super_class{

    protected $CI;

    public function __construct(){
        parent::__construct();

        $this->CI =& get_instance();
    }

    public function do_somthing( $param1 = NULL ){
        //param1 as array
        $this->CI->db->insert('table', $param1);
    }

    public function check_login(){
        $this->CI->load->library('session');

        return ( ! empty($this->CI->session->userdata('id'))) ? TRUE : FALSE;
    }
}
?>
