Hi There
I need help with my sessions. I'm trying to carry over values in a form when the use selects the next button.
I keep getting these errors
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/special1-2-1.php:7) in /home/special1-2-1.php on line 7
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/special1-2-1.php:7) in /home/special1-2-1.php on line 7
Here is my php code:
<?php session_start();
if ( isset($_POST["item"]) || isset($_POST["price"]) || isset($_POST["FRM_3"]) )
{
$_SESSION["page1"] = $_POST["item"];
$_SESSION["page1"] = $_POST["price"];
$_SESSION["page1"] = $_POST["FRM_3"];
header("location: ./special1-2-2.php");
}
?>
Does anyone have any iedas?:confused:
You'll have to put this code at the very beginning of the PHP document, you can't use any HTML before it, at all.

It is!
The above code is just after the </head> and before the <body> tages
i have javascript after the php code as well
so i have
</head>
<?php
the above php code
?>
<SCRIPT LANGUAGE="JavaScript">
all my javascript stuff
</script>
<body>
all my html stuff
</body>
</html>
:confused:
It should be before anything. Before the <HTML> tag, and even before your DTD. It should first have the PHP code, then have the HTML.

this will just give you an idea of what i'm trying to do
http://www.cityscout.ca/test/special1-2-1.php
:D
It looks like the code works... I don't see what the problem is. :confused:
Maybe you should try using $_SESSION["page1_1"], $_SESSION["page1_2"], and so on, instead of using three $_SESION["page1"] variables?

INSERT INTO ordertemp (item,price,topings,extras,drinks) VALUES ('Single 16 Inch Extra Large W/Pop','13.99','','','')
<?php session_start();
if ( isset($_POST["item"]) || isset($_POST["price"]) || isset($_POST["topings"]) )
{
$_SESSION["item"] = $_POST["item"];
$_SESSION["price"] = $_POST["price"];
$_SESSION["topings"] = $_POST["topings"];
header("location: ./special1-2-2.php");
}
?>
you can see it's grabing item, and price but not topings..
topings is a list box, that the user can select many items
that's where i'm having the problems it not getting the list box items

I have attached a txt file of the code i'm using for the first page you see..
You mean a multiple-select box? In that case, you'd have to name the box name[] but change "name" to whatever you want to name it. Then in PHP, loop through its values. That's the only way to do it.

If you go to the link above you will see you can add as many items as you want to the left list box.. That's the box i want to carry over
An example can be found at http://cmm.sonoracabinets.com/testing/selAry.php
<?PHP
if(!isset($_GET["node"]) || $_GET["node"] != "process" && !isset($_POST["submit"])){
?>

what do you mean by that?
It's a multiple select box. Click One, then hold shift and click Three. It will select the first three options. Then click Submit Query. ;)

Hi There
I have been working with the above example and have had no luck..
I'm still confused on how to carry the values of the third list box over to latter (at end be instered into a database)
The name should have [] after it, so that PHP can treat its values as an array.

But adding [] will that not effect my javascript code?
