Hello everyone,
I built a sample e-banking application as part of a project from my school. I wrote the statement below to update two tables from fields submitted from a form and also send a mail to the form owner. when i submit the form it redirects to the finale.php page but does not update the database at all…
The UPDATE statement is
$sqlupdate = " UPDATE client, statement SET client.account_balance = $balanceaftertransfer,client.checkcode = 1, statement.account_balance = $balanceaftertransfer, statement.statement_details = Online Transfer, statement.statement_credit = 0, statement.staement_debit = $amt2tra, statement.statement_date = CURDATE(), statement.client_id = $client_id
WHERE client.client_id = statement.client_id AND username = ‘“.$_SESSION[‘MM_Username’].”’";
mysql_query($sqlupdate ) ;
and the full post.php file is as shown below
<?php
if (!isset($_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;
}
$MM_restrictGoTo = “log.php”;
if (!((isset($_SESSION[‘MM_Username’])) && (isAuthorized(“”,$MM_authorizedUsers, $_SESSION[‘MM_Username’], $_SESSION[‘MM_UserGroup’])))) {

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);
