Passing Session Variables - Help?

Passing Session Variables - Help?

Hi all,

I'm having trouble trying to pass a variable from one page/form to another and hope you can help.

I have two tables - prop_details and prop_images - I created a relationship using prop_id in both tables.

My first insert form posts data to prop_details and then redirects to my second page/form where I want to display two session variables (prop_id and prop_ref from prop_details) and then pass those to prop_images to create the relationship.

I have created a recordset in my 2nd page/form but cannot display the two session variable to post to prop_images

SELECT prop_id, prop_ref
FROM prop_details
WHERE prop_id = colname

what am I doing wrong?

With thanks

Phil

Add code to the top of your page:

<?php
if (!session_id()) session_start();
?>

Still no joy

Hi Ray

Thanks for your help.

I have added that the the top of my second page and still can't get the 2 session variables to display. I've spent 3 days on this now and I'm sure I'm doing something simple wrong, but can't see the wood for the trees.

My code now looks like this

<?php
if (!session_id()) session_start();
?>
<?php require_once("../Connections/prop.php"); ?>
<?php require_once("../WA_DataAssist/WA_AppBuilder_PHP.php"); ?>
<?php require_once('../Connections/prop.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

$colname_Recordset1 = "-1";
if (isset($_SESSION['prop_id'])) {
$colname_Recordset1 = (get_magic_quotes_gpc()) ? $_SESSION['prop_id'] : addslashes($_SESSION['prop_id']);
}
mysql_select_db($database_prop, $prop);
$query_Recordset1 = sprintf("SELECT prop_id, prop_ref FROM prop_details WHERE prop_id = %s", GetSQLValueString($colname_Recordset1, "int"));
$Recordset1 = mysql_query($query_Recordset1, $prop) or die(mysql_error());

The problem must be where they are set, since they are referenced correctly here.

have i set them wrong?

Here's my first page. Does dataassist set them automatically or do I need to manually set them somehow?

Update

Hi Ray

I figured it out and added

$_SESSION['WADA_Insert_prop_details'] into my recordset for my second form, WADA_Insert_prop_details being the session variable from my first form and that seems to work fine.

Thanks for your help.

Regards

Phil
