<?whats wrong with this picture?>

Aviezero

i want to enter my info in on the entry screen and proceed to the shop.php and have it show the info.
everything works fine except the session id ( i think )
im fairly new with php so im sure its an simple problem im missing.
[i want it to check the cookie to see if ive already got a previous entry. if i do have a previous cookie entry i want to use that info, if i dont have a previous cookie entry i want to create one. (dont really care about the other stuff) maybe this will be a challenge to somebody else too. would appreciate any positive response.

entry.php

<?
session_start();
session_register("sessionver");

if(!$HTTP_COOKIE_VARS["sessionid"])
{
$sessionver = 2;
}
else
{
$sessionver = 3;
}
echo "sessionver = ".$sessionver."<br>";

<form action="shop.php" method=post>

shop.php

<?
session_start();
//session_register("session", "scid");

echo $sessionver; / this shows fine /

if ($sessionver = 2)
{
$session = md5(uniqid(rand()));

setcookie("sessionid", $session, time() + 35); / says headers already sent /
}
if ($sessionver = 3)
{
$session = $HTTP_COOKIE_VARS["sessionid"];
}

$table = "inventory"; / for sql implementation later /

echo "session: ".$session."<br>"; / doesn't show $session /
echo "table: ".$table."<br>"; / shows fine /
echo "product: ".$product."<br>"; / shows fine /
echo "quantity: ".$quantity."<br>"; / shows fine /

When using a file field, I don't think PHP handles it as a post variable. For instance, $filefield_name returns the filename as it was sent, and $filefield_type returns the file type as it is known to the server.

not really sure i know if that helps me ... could you explain more about how that gives me my "header already sent error"

this is what is shown after sent to php engine

2
Warning: Cannot add header information - headers already sent by (output started at d:\shoppingcart\shop.php:5) in d:\shoppingcart\shop.php on line 10

Warning: Undefined index: sessionid in d:\shoppingcart\shop.php on line 14
session:
table: inventory
product: mouse
quantity: 3

stolzyboy

correct mordecai

Aviezero

that fixes why my $session wasnt showing up but i still cant make the cookie because it says
"Warning: Cannot add header information - headers already sent by (output started at d:\shoppingcart\shop.php:4) in d:\shoppingcart\shop.php on line 9"
so it will always be a new session id number
any ideas?

stolzyboy

try using

ob_start();

at the beginning of the page, like after the

session_start();

that turns output buffering on allowing the script to internally buffer allowing you to use headers and things like setcookie not just at the beginning of scripts
