Need Help Please

Hi I could do with some advice.

I am trying to pass a variable from one script to another. But cannot seem to get it to work. The code is below:

1. The first script sets the ordeid value to 1

$HTTP_SESSION_VARS['orderid'] = '1';

if (isset($HTTP_SESSION_VARS['orderid']))
{
$order = $HTTP_SESSION_VARS['orderid'];
$db = mysql_connect ('xxxxxxxxxx', 'xxxxxxxxxxxxx', 'xxxxxxxxx');
mysql_select_db ('xxxxxxx');
$query = "Select product, price from productsordered where orderid = ".$order."";
$result = mysql_query ( $query ,$db);

2. On the second page (or Script) I am trying to check if the variable orderid from the previous script is set. I have tested the first page and it sets the variable for that page allowing it to work fine. But when i move over to this script it never retrives the value?

if (isset($HTTP_SESSION_VARS['orderid']))

{

$order = $HTTP_SESSION_VARS['orderid'];

*************more code. I didint think it was needed

Am I Coding it right can someone point me in the right direction.

Thanks All
🆒

Did you call session_start() on the second script?

Warning: Cannot send session cache limiter - headers already sent (output started at /homepages/14/*****/htdocs/carttest.php:7) in /homepages/14/******/htdocs/carttest.php on line 129

This Is The Full Code For The Page

<?php 
session_start();
if (isset($HTTP_SESSION_VARS['orderid']))

{

$order = $HTTP_SESSION_VARS['orderid'];

$db = mysql_connect ('', '', '');

mysql_select_db ('db76275624');

$query = "Select product, price, rewardpoints, productnumber from productsordered where orderid = ".$order."";

$result = mysql_query ( $query ,$db);

$totalrewardpoints = 0;

$totalprice = 0.00;

echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">";
echo "<tr>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "</tr>";
echo "<tr>";
echo "<td width=\"24\">&nbsp;</td>";
echo "<td>&nbsp;</td>";
echo "<td> <p class=\"Text1\"><u><strong>Product ID</strong></u></p></td>";
echo "<td width=\"39%\"> <p class=\"Text1\"><strong><u>Product Name</u></strong></p></td>";
echo "<td width=\"21%\"><p class=\"Text1\"><strong><u>Reward Points</u></strong></p></td>";
echo "<td width=\"19%\"><p class=\"Text1\"><strong><u>Price</u></strong></p></td>";
echo "</tr>";
echo "</table>";

while ($myrow = mysql_fetch_array($result))

{
echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">";
echo "<td width=\"5%\"><img src=\"../PCShop/images/bullet.gif\" width=\"24\" height=\"19\"></td>";
echo "<td width=\"16%\"><p class=\"Text1\">".$myrow["productnumber"]."</p></td>";
echo "<td width=\"39%\"><p class=\"Text1\">".$myrow["product"]."</p></td>";
echo "<td width=\"21%\"><p class=\"Text1\">".$myrow["rewardpoints"]."</p></td>";
echo "<td width=\"19%\"><p class=\"Text1\">&pound;".$myrow["price"]."</p></td>";
echo "</table>";
$totalrewardpoints += $myrow["rewardpoints"]; 
$totalprice+= $myrow["price"]; 
}}

?>

The Error Line Is 129

session_start();

can i suggest you edit that post quick and take out your username and passwords from the db connection string: we're not all as honest as some.

[jpmoriarty]

and how can that be line 129 when it's the first thing you've posted? You cant have HTML above it, it has to be the first thing that you send to the browser (that might not be strictly true, i've seen people refer to an ob_start or something, but it's a good rule of thumb anyway).

You must send that session_start as the first thing to the browser. It can occur quite late in your pHP, but there cant be anything echoed to the browser before it otherwise it wont work

Hey, Mr. Moriarty...I like your sig. Have you thought about making the echo() output dependent upon the value of a variable called by rand() ?? 😃
