3、inc/singup.php

<?php
define ('XAJAX_DEFAULT_CHAR_ENCODING', 'gb2312' );
//注意这里，必须要设置gb2312，不然中文会乱码
require_once("xajax.inc.php");
require_once("function.php");
$xajax = new xajax();
$xajax->registerFunction("processForm");
//同reg.php文件

function processForm($aFormValues)
{
$objResponse = new xajaxResponse();
require_once("conn.php");
$usr=$aFormValues['usr'];
$email=$aFormValues['email'];
$pwd=$aFormValues['pwd'];
$pw=Md5($pwd);
$errmsg="";
//要过滤的非法字符
$ArrFiltrate=array("'",";","union");

foreach($aFormValues as $key=>$value){
if (FunStringExist($value,$ArrFiltrate)){
$objResponse->addAlert("输入的信息含有非法字符"' ; union!"");
$objResponse->addAssign("submitButton","value","继续");
$objResponse->addAssign("submitButton","disabled",false);
return $objResponse;
}
}

if (trim($usr) == "")
{
$errmsg.="请输入用户名!n";
}
if (trim($pwd) == "")
{
$errmsg.="请输入密码!n";
}
if ($pwd != $aFormValues['pwd2'])
{
$errmsg.="两次输入的密码不一致!n";
}

if (!CheckEmailAddr($email))
{
$errmsg.="邮件地址不正确!n";
}
$sql="select * from zl_usr where zl_usr='$usr'";
$result=mysql_query($sql,$db);
if($myrow=mysql_fetch_array($result)){
$errmsg.="用户名已经存在!n";
}
if ($errmsg=="")
{
$sForm = "注册成功<br>用户名:".$usr."<br>email:".$email."";
$sql="insert into zl_usr(zl_usr,zl_pwd,email) values('$usr','$pw','$email')";
$result=mysql_query($sql,$db);
$objResponse->addAssign("formDiv","innerHTML",$sForm);
}
else
{
$objResponse->addAlert($errmsg);
//弹出错误信息
$objResponse->addAssign("submitButton","value","继续");
//修改submitButton的value为继续
