实例说明制作一个php+mysql留言本

复制代码代码如下:

<?php require_once('Connections/conn.php'); 
require_once('inc/accesscheck.php'); 
require_once('inc/GetSQLValueString.php');?> 
<?php 
if ((isset($_GET['postid'])) && ($_GET['postid'] != "")) { 
$updateSQL = sprintf("UPDATE posts SET checked=1-checked WHERE postid=%s", 
GetSQLValueString($_GET['postid'], "int")); 
mysql_select_db($database_conn, $conn); 
$Result1 = mysql_query($updateSQL, $conn) or die(mysql_error()); 
$deleteGoTo = "adminmain.php"; 
if (isset($_SERVER['QUERY_STRING'])) { 
$deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?"; 
$deleteGoTo .= $_SERVER['QUERY_STRING']; 
} 
header(sprintf("Location: %s", $deleteGoTo)); 
} 
?>

复制代码代码如下:
