Sessions and Objects in Php 4.0.6

[alexaugot]

Hi,

I'm trying to write a little shopping cart for a client, and I've decided to use sessions to store the item data. I've created an simple objects class with a constructor and a few accessors, just to hold the data in.

I wrote a script to test the sessions, but it doesn't seem to be working right. Everytime I test the session data (I just fill a dummy Item object), it just seems to overwrite itself. I've got --enable-track-vars on, so I dont think that's what's causing the problem.

Anyone have any idea what I'm doing wrong? Here's some of my code -

<?php

// Cart Checkout, View, Modify and Review Script
// Written by Alex Augot - [e-mail]
// -------------------------------------------------
// Ok, so this is the big chunk of code. It allows
// the user to view and modify their shopping cart

require("cart_class_include.php");
require("cart_session_include.php");

switch($action){

case "add_to_cart":
add_to_cart($prev_page, $cust_id, $item_name, $item_description, $item_price, $item_quanity);
break;

default:
break;

}

function add_to_cart($prev_page, $cust_id, $item_name, $item_description, $item_price, $item_quanity){

if($s_cust_id != $cust_id){
	print("1 $s_cust_id<br>");
	print("2 $cust_id<br><br>");
	print("There has been an error in the shopping cart system.  Please go <a href=\"$prev_page\">back
	and try again");
exit();
}

if($HTTP_SESSION_VARS[count($HTTP_SESSION_VARS)] = new Item($item_name, $item_description, $item_price, $item_quanity, $prev_page)){
	print("Item added correctly<br><br>");
}

for($temp1=0; $temp1 < count($HTTP_SESSION_VARS); $temp1++){
	$temp_obj = $HTTP_SESSION_VARS[$temp1];
	if(is_object($temp_obj)){
		$temp_obj->printReport();
	}else{print("$temp-obj");}
}

}

?>
<?php include("cart_add_include.php"); ?>

<?php
session_start();
/*
// Cart Session Include Script. Must be included on EVERY page
// Written by Alex Augot - [e-mail]

// Variable Declerations
// s_cust_id - The unique ID of the customer
*/
if(!(session_is_registered('s_cust_id'))){
$s_cust_id = session_id();
$s_remote_ip = $REMOTE_ADDR;
session_register('s_cust_id');
session_register('s_remote_ip');
}else{
print("Printing session id - $s_cust_id<br><br>");
}

print("<!-- BEGINNING CART CODE -->");

print("<!-- ENDING CART CODE -->");
?>

I think session_start() has to be the first thing called on a page. You are calling the cart_include.php first.

maybe try changing the order
