HI,
Im trying to adapt a shopping cart script for an alternative use, on my local host XXMP scrip code works fine, but when i upload to my host I have problems,
Im making a Role-play page to assist with npc encounters, where you can add npc's to the encounter (Shopping Cart) see http://rptoolkit.com/encounter/ which is active and working
The issue is when I go to remove 1 of the 4 people from the encounter (Cart) it will remove all and duplicate the first entry on 2 lines, where this doesn't happen on my localhost.
Hope you can help shed some light as I'm confused why it will work on 1 but not the other maybe has to do with my PHP Versions.
Thanks.
----------------------------------------------------
Script code is below for the remove link button on the index page
echo '<td><span> <a href="include/encounter_update.php?removep='.$cart_itm["code"].'&return_url='.$current_url.'"><img src="images/icon_delete.gif" alt="Delete"></a> </span></td>';
Script below is the encounter update script (encounter_update.php)
<?php
session_start();
include_once("config.php");
//empty cart by distroying current session
if(isset($_GET["emptycart"]) && $_GET["emptycart"]==1)

session_destroy();
header('Location:'.$return_url);
}
//add item in encounter
if(isset($_POST["type"]) && $_POST["type"]=='add')
{
$id = filter_var($_POST["id"], FILTER_SANITIZE_STRING); //product code
$product_qty = filter_var($_POST["product_qty"], FILTER_SANITIZE_NUMBER_INT); //product code
$return_url = base64_decode($_POST["return_url"]); //return url
//limit quantity for single product
if($product_qty > 10){
die('<div align="center">This demo does not allowed more than 10 quantity!<br /><a href="http://sanwebe.com/assets/paypal-shopping-cart-integration/">Back To Products</a>.</div>');
