Codeigniter-在我的库中加载模型

Question

I'm about to write my own library in codeigniter to check if the logged in user is an admin or not. To do that I need to compare a value with the value of the typeAccount in the DB. Because I'm still learning the MVC pattern I had a question about this before starting to write my library. Can I load a model in my library? Or should I communicate directly to my DB in my library? Or is there a better way to approach this?

Answer 1

Yes, you can load your model to into your library, simply add CI.

class Validator
{
    private $CI = null; 
    function __construct()
    {
        $this->CI =& get_instance();
    }

    public function validate_merchantaccount_status($param)
    {
        //Code Here
        $this->CI->load->model('merchantaccount_model');
        $res_merchant = $this->CI->merchantaccount_model->get_list($param);

    }
}

Dont forget to make your model.

Answer 2

Since the library is some kind of logic, you can see it as a piece of the Controller. The Controller usually just loads a Model to use it.

So yes just load the Model from CodeIgniter instead of connecting to the database yourself.

Makes your code more DRY too.

Answer 3

Make you models

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class My_model extends CI_Model
{
/// Here the code
}

And then in controller use

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

Ant i think that is best approach :)
