Hi, I've got a form that calculates checkbox values and puts them in a total field called txtTotal. When the user clicks send, I need to pass the total to a payment page. The form page has PHP
session_start();
$_SESSION['sessTotal'] = $_POST['txtTotal'];
and the payment page has
session_start(); at the top of the page and <?php echo $_SESSION['sessTotal']; ?> where I want the total to display. The total does not carry over to the payment page and I can't work out why.
Here is all the PHP from the form page as I'm pretty new to PHP and not sure if there's a conflict (should session_start appear more than once?) Thanks guys
<?php require_once('Connections/df.php'); ?> <?php //initialize the session if (!isset($_SESSION)) { session_start(); $_SESSION['sessTotal'] = $_POST['txtTotal']; } // ** Logout the current user. ** $logoutAction = $_SERVER['PHP_SELF']."?doLogout=true"; if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){ $logoutAction .="&". htmlentities($_SERVER['QUERY_STRING']); } if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")){ //to fully log out a visitor we need to clear the session varialbles $_SESSION['MM_Username'] = NULL; $_SESSION['MM_UserGroup'] = NULL; $_SESSION['PrevUrl'] = NULL; unset($_SESSION['MM_Username']); unset($_SESSION['MM_UserGroup']); unset($_SESSION['PrevUrl']); $logoutGoTo = "index.php"; if ($logoutGoTo) { header("Location: $logoutGoTo"); exit; } } ?> <?php if (!isset($_SESSION)) { session_start(); } $MM_authorizedUsers = ""; $MM_donotCheckaccess = "true"; // *** Restrict Access To Page: Grant or deny access to this page function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) { // For security, start by assuming the visitor is NOT authorized. $isValid = False; // When a visitor has logged into this site, the Session variable MM_Username set equal to their username. // Therefore, we know that a user is NOT logged in if that Session variable is blank. if (!empty($UserName)) { // Besides being logged in, you may restrict access to only certain users based on an ID established when they login. // Parse the strings into arrays. $arrUsers = Explode(",", $strUsers); $arrGroups = Explode(",", $strGroups); if (in_array($UserName, $arrUsers)) { $isValid = true; } // Or, you may restrict access to only certain users based on their username. if (in_array($UserGroup, $arrGroups)) { $isValid = true; } if (($strUsers == "") && true) { $isValid = true; } } return $isValid; } $MM_restrictGoTo = "index.php"; if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) { $MM_qsChar = "?"; $MM_referrer = $_SERVER['PHP_SELF']; if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&"; if (isset($_SERVER['QUERY_STRING']) && strlen($_SERVER['QUERY_STRING']) > 0) $MM_referrer .= "?" . $_SERVER['QUERY_STRING']; $MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer); header("Location: ". $MM_restrictGoTo); exit; } ?> <?php if (!function_exists("GetSQLValueString")) { function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") { if (PHP_VERSION < 6) { $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; } $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue); switch ($theType) { case "text": $theValue = ($theValue != "") ?

OK I got it. I needed
session_start();
$_SESSION['sessTotal'] = $_POST['txtTotal'];
on the payments page as well, not just session_start();
