Adding coop to Invasion Powered board (IPB) 2.1.6

I had an opportunity to work for a client who wanted to me to put coop ads on his IPB Powered board.
After doing a research I found a article but that was for an older version, but it gave me an idea how to add coop to it hence i did this and got success with it.

On IPB 2.1.6:
In your IPB directory.
>>Look for ForumDIR/sources/classes/class_display.php.
>>Download, backup and open class_display.


Find:

$this->ipsclass->skin['_wrapper'] = str_replace( "<% CHARSET %>"        , $this->ipsclass->vars['gb_char_set'], $this->ipsclass->skin['_wrapper']);

Code (markup):

Add below:

ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../');
include ('ad_network_428.php');
$ad_network = substr_replace($ad_network," ,strpos(substr($ad_network,strpos($ad_network,"|")+1),"|") + strpos($ad_network,"|")+1,1);
$this->ipsclass->skin['_wrapper'] = str_replace( "<% COOP.AD.NETWORK %>" , $ad_network, $this->ipsclass->skin['_wrapper']);

Code (markup):

--------------------------------------------


If your ad file is called something other than ad_network_488.php, change the include to your file name.

Upload class_display.php

3. Log into AdminCP and go to your Skin Manager and edit the Board Wrapper for your skin(s)

Place <% COOP.AD.NETWORK %> wherever you want the ads to show (I have them under the Copyright section at the bottom)

Save and you are done
Rest as .Here

 

Anyone had any joy getting this to work on IPB 2.2?

 

I didnt upgraded to 2.2 yet

 

This works for 2.2 also

 

Can anyone sort this out for v2.3.x?
