PHP and XML image gallery variable issue


Posted on 16th Feb 2014 07:03 pm 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++;
}
?>
