CodeIgniter Third party class not loading - php

Question

I am trying to implement Dashboard widget class (found here: http://harpanet.com/programming/php/codeigniter/dashboard/index#installation) but it is giving me error Unable to load the requested class
I have tried to add this class in autoload as well as menually to my controller $this->load->library('dash') but this also giving the same error.
I have checked dash.php and found below method private function __example__() but can't understand what the developer is saying in comment.
class Dash
{
private function __example__()
{
/*
* This function is purely to show an example of a dashboard method to place
* within your own controller.
*/
// load third_party hArpanet dashboard library
$this->load->add_package_path(APPPATH.'third_party/hArpanet/hDash/');
$dash =& $this->load->library('dash');
$this->load->remove_package_path(APPPATH.'third_party/hArpanet/hDash/');
// configure dashboard widgets - format: type, src, title, cols, alt (for images)
$dash->widgets = array(
array('type'=>'oop', 'src'=>'test_dash', 'title'=>'Test OOP Widget', 'cols'=>3),
// if 'title' is set to FALSE, the title block is omitted entirely
// note: this is an 'html' widget but is being fed content from a local method
array('type'=>'html', 'src'=>self::test_method(), 'title'=>false, 'cols'=>3),
array('type'=>'file', 'src'=>'saf_inv.htm', 'title'=>'Safety Investigation'),
// multi-content widget - set widget title in outer array (also note use of CI anchor to create a link)
array('title'=>anchor('tz', 'TARGET ZERO'),
// sub-content follows same array format as single content widget
// 'img' content can also have an 'alt' text
array('type'=>'img', 'src'=>'saf_tzout.gif', 'alt'=>'Action Completed'),
array('type'=>'file', 'src'=>'saf_tz.htm'),
array('type'=>'file', 'src'=>'ave_close.htm', 'title'=>'Average Time to Close')
),
array('type'=>'file', 'src'=>'saf_meet.htm', 'title'=>'Safety Meeting'),
array('type'=>'file', 'src'=>'saf_acc.htm', 'title'=>'Accident Investigation'),
array('type'=>'file', 'src'=>'saf_hazmat.htm', 'title'=>anchor('hazmat', 'HAZMAT')),
array('type'=>'file', 'src'=>'saf_cont.htm', 'title'=>'Loss of Containment'),
array('type'=>'file', 'src'=>'saf_worksinfo.htm', 'title'=>'Works Information'),
// an action widget - 'clear' will generate a blank widget with a style of clear:both
array('type'=>'clear'),
// multi-content widget - width can be set using the 'cols' param in outer array
array('title'=>'RAG Report', 'cols' => 2,
array('type'=>'file', 'src'=>'saf_rag.htm'),
array('type'=>'img', 'src'=>'ProcSaf.gif')),
array('type'=>'file', 'src'=>'saf_chrom.htm', 'title'=>'Chrome checks'),
);
// populate the view variable
$widgets = $dash->build('safety');
// render the dashboard
$this->load->view('layout_default', $widgets);
}
...................
} // end of Dash class
Installation path is root/application/third_party/hArpanet/hDash/libraries/dash.php
How can I load this class to my system and use widgets?

Answer 1

You have to create a library that initialize the third party class:
for Eg:
--in library create a file named mydash.php --
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MyDash
{
public function __construct()
{
require_once APPPATH.'third_party/hArpanet/hDash/libraries/dash.php';
}
}
load the library using:
$this->load->library('mydash');
then you are able to use the Dash class. Also able to load library in autoload.
Thank you...

Sorry to hear you were having problems, (I've only just noticed this SO entry). Thanks to ReNiSh for his workaround, much appreciated.
You do not however need to use the library approach to implement the 'require_once' of hDash. I have now written a walkthrough for getting hDash installed and running, which you can find here: http://harpanet.com/programming/php/codeigniter/dashboard/walkthrough
Also, note that as of yesterday, 3rd Feb 2014, hDash has been updated to version 1.2.

I am using PDF Parser from http://pdfparser.org/
I create files application/libraries/pdf.php
class Pdf
{
public function __construct()
{
require_once APPPATH."/third_party/pdfparser.php";
}
}
Then I create file application\third_party\pdfparser.php
if (!defined('pdfparser')) {
define('pdfparser', dirname(__FILE__) . '/');
require(pdfparser . 'pdfparser/autoload.php');
}
Last, I include PDF Parser Library in Directory => application\third_party\pdfparser
