<?php

復(fù)制代碼代碼如下:

<?php 
//該函數(shù)用于將一般字符串轉(zhuǎn)換成SQL語句所需要的格式 
function GetSQLValueString($theValue, $theType) 
{ 
$theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue; 

switch ($theType) { 
case "text": 
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL"; 
break; 
case "int": 
$theValue = ($theValue != "") ? intval($theValue) : "NULL"; 
break; 
} 
return $theValue; 
} 
?> 

復(fù)制代碼代碼如下:

<?php 
session_start(); 

//如果Session不存在，則跳轉(zhuǎn)到Admin.php 
if (!(isset($_SESSION['MM_Username']))) { 
header("Location: admin.php"); 
exit; 
} 
?> 

復(fù)制代碼代碼如下:

<?php require_once('Connections/conn.php'); ?>

session_start(); 

$loginFormAction = $_SERVER['PHP_SELF']; 
if (isset($accesscheck)) {

$LoginRS = mysql_query($LoginRS__query, $conn) or die(mysql_error()); 
$loginFoundUser = mysql_num_rows($LoginRS); 
if ($loginFoundUser) { 
$loginStrGroup = ""; 

//declare two session variables and assign them
