4、inc/login.php 登陆用的处理文件
复制代码 代码如下:
<?php
define ('XAJAX_DEFAULT_CHAR_ENCODING', 'gb2312' );
require_once("xajax.inc.php");
require_once("function.php");
$xajax = new xajax();
$xajax->registerFunction("processForm");
function processForm($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";
}
$sql="select * from zl_usr where zl_usr='$usr' and zl_pwd='$pw'";
$result=mysql_query($sql,$db);
if(!$myrow=mysql_fetch_array($result)){
$errmsg.="用户名不存在,或密码错误!\n";
}
if ($errmsg=="")
{
$sForm = "登陆成功";
$objResponse->addAssign("formDiv","innerHTML",$sForm);
}
else
{
$objResponse->addAlert($errmsg);
$objResponse->addAssign("submitButton","value","继续");
$objResponse->addAssign("submitButton","disabled",false);
}
return $objResponse;
}
$xajax->processRequests();
?>
登陆于注册原理差不多，就不废话了：）
另外下面是两个用到的文件代码 conn.php function.php
conn.php
复制代码 代码如下:
