PHP and XML image gallery variable issue

Posted on 16th Feb 2014 by admin

I'm trying to display the large image on the same page as the thumbnails, to do that I'm passing a variable called $current. I know that the code to display large image works, because it works when no variables are passed along, in which case $current set to 0, but when i click on any other thumbnail, the xml info doesn't seem to be passed along. I check if $current is passed into test_table.php in the top right corner so I know that works. So I'm stuck, please help! Thanks!

The problem page can be found here: http://brooklynthings.com/tibet_carpet_test/test_table.php

Code: [Select]<?php
include 'carpets.php';
$xml = new SimpleXMLElement($xmlstr);
$item_count=-1; //fixes item count
$id=$_GET['id'];
if (isset($id)==false){
$id=0;
}
$page=$_GET['page'];
if (isset($page)==false){
$page=1;
}
$id_count=($page-1)*15;
foreach ($xml->rug as $rugs) {
$item_count++;
}
$current=$_GET['id_current'];
if (isset($current)==false){
$current=0;
}

$pages=round($item_count/15);
if(($item_count/15)-($pages*15)!=0){ // adjusts page number for overflow
$pages++;
}
?>
