here is the a modified code for the current comment system for php fusion v7 i was wondering if someone can mod it and make a workin ajax verion. because i have a video site and each time someone posts a comment the page has to reload.

<?php

if (!defined("IN_FUSION")) { die("Access Denied"); }

include LOCALE.LOCALESET."comments.php";

//	|-------------------|	Some Required VSariables		|-----------------------|
$settings2 = dbarray(dbquery("SELECT comments_captcha_enable, comments_order FROM ".DB_SETTINGS));

// 1 = enable captcha, anything else will disable this mod 
$enable_captcha = $settings2['comments_captcha_enable']; 

// based on your preferences, you might want to make it "ASC"
// which is ascending or "DESC" which is decending 
if($settings2['comments_order'] == 0)	
$order		= "DESC";
else
$order		= "ASC";

// leave this blank
$error 			= ""; 		
//	|-------------------|			MOD ends			|-----------------------|
