Session not showing on certain pages

ralphonzo · Aug 13, 2012

I've got a cart that displays products when they're added, but not simply viewed. Try it @ [URL unfurl="true"]http://lxyltd.com/products.html[/url]. I don't understand why the count($_SESSION["cart_array"]) displays '0' when there's clearly something in it!

Here's the code that sits inside an iFrame on the page:

Code:

<?php 
session_start(); // Start session first thing in script
// Script Error Reporting
error_reporting(E_ALL);
ini_set('display_errors', '1');
// Connect to the MySQL database  
include "storescripts/connect_to_mysql.php"; 

function money_format($format, $number) { 
    $regex  = '/%((?:[\^!\-]|\+|\(|\=.)*)([0-9]+)?'. 
              '(?:#([0-9]+))?(?:\.([0-9]+))?([in%])/'; 
    if (setlocale(LC_MONETARY, 0) == 'C') { 
        setlocale(LC_MONETARY, ''); 
    } 
    $locale = localeconv(); 
    preg_match_all($regex, $format, $matches, PREG_SET_ORDER); 
    foreach ($matches as $fmatch) { 
        $value = floatval($number); 
        $flags = array( 
            'fillchar'  => preg_match('/\=(.)/', $fmatch[1], $match) ? 
                           $match[1] : ' ', 
            'nogroup'   => preg_match('/\^/', $fmatch[1]) > 0, 
            'usesignal' => preg_match('/\+|\(/', $fmatch[1], $match) ? 
                           $match[0] : '+', 
            'nosimbol'  => preg_match('/\!/', $fmatch[1]) > 0,

Sorry guys, I think it's a case of Adobe Muse being obstructive. I've scripted the entire pages and it all works fine. Perhaps Adobe want everyone to use their own BC system!! Sorry for the hassle!
