I am unable to load my custom class which doesnot extend from any core class. I have placed my custom class in a subfolder inside application/libraries.

So here is my folder structure

application
    |_ libraries
      |_ cgh
          |_ cgh_asset.php
          |_ cgh_article.php
          |_ cgh_asettype.php
    |_ controllers
      |_ welcome.php

Cgh_article is a subclass of Cgh_asset

Cgh_asset.php :

<?php if ( ! defined( BASEPATH )) exit( No direct script access allowed ); 
abstract class Cgh_asset
{
    public $id;
    public $type;
    public $title;
    public $content;
    public $user;

    abstract public function generate_url();
    function __construct()
    {
        $this->generate_url();
    }
}

?> 

Cgh_article.php :

<?php

if ( ! defined( BASEPATH )) exit( No direct script access allowed ); 

class Cgh_article extends Cgh_asset
{
    function __construct()
    {
        parent::__construct();
        $this->type=Cgh_assettype::article;
    }
    function generate_url()
    {
        $this->url="Article_URL";
    }
}


?> 

Cgh_assettype.php:

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

class Cgh_assettype
{
    const type1="type1";
    const type2="type2";
    const article="article";
}

?> 

主计长欢迎.php

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

class Welcome extends CI_Controller {

    public function index()
    {
        $this->load->library( cgh/Cgh_assettype , cgh/Cgh_asset , cgh/Cgh_article );

        $this->load->view( welcome_message );
    }
} 

The error I get is : Unable to load the requested class: Cgh_assettype

我必须尝试所有可能的上下级案件组合,这些类别的名称、档案名称,但错误总是一样的。

After going through some answers, I think probably I should add one basic question here - Is it at all possible to have my own custom object types within codeigniter ... types that should be quite obvious from my question ?

在我看来,这似乎对我来说是可行的。

在我的控制师的构造中,我需要——我的班级......好事是,我可以把我的班子合并为一个单一档案——我的班子最初是一只手脚。 ——这是我经过修改后的控制者,这项工作:

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

class Welcome extends CI_Controller {


    public $cgh_assettype;
    public $cgh_asset;
    public $cgh_article;

    function __construct()
    {
        parent::__construct();
        //$this->load->library(array( cgh/cgh_assettype , cgh/cgh_asset , cgh/cgh_article ));
        echo "Including CGH<br />";
        echo "<p>Apppath is ". APPPATH. "</p>";
        require_once(APPPATH. libraries/cgh/Cgh_assettype.php );
        require_once(APPPATH. libraries/cgh/Cgh_asset.php );
        require_once(APPPATH. libraries/cgh/Cgh_article.php );

    }

    public function index()
    {
        $iCgh_article=new Cgh_article();
        echo "<p>$iCgh_article->url</p>";
        $this->load->view( welcome_message );
    }
}
