我有一个代码,它通过AJAX登录,然后将数据传递到.php文件,以检查它与SQL.对于一个测试,用户名和密码是我 - 但是即使这从检查回来它没有登录我,似乎会话没有被设置.
log.php
<script type="text/javascript">
$(document).ready(function()
{
$("#login_form").submit(function()
{
//remove all the class add the messagebox classes and start fading
$("#msgbox").removeClass().addClass('messagebox').text('Validating....').fadeIn(1000);
//check the username exists or not from ajax
$.post("ejaxlog.php",{ username:$('#username').val(),password:$('#password').val(),rand:Math.random() } ,function(data)
{
if($.trim(data)=='yes') //if correct login detail
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Logging in.....').addClass('messageboxok').fadeTo(900,1,
function()
{
//redirect to secure page
document.location='http://www.google.com';
});
});
}
else
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Your login detail sucks...').addClass('messageboxerror').fadeTo(900,1);
});
}
});
return false; //not to post the form physically
});
//now call the ajax also focus move from
$("#password").blur(function()
{
$("#login_form").trigger('submit');
});
});
</script>

然后它通过下一个代码检查MySQL,它是否成功它回应"我"在我的HTTP头中看到的(是的必须是正确的)但它并没有将我重定向到日志中指定的"eindex.php". php文件.
<?php
session_start();
require("../mcfrdb.php");
// Included database once using the require method
?>
<?php
$username = mysql_real_escape_string(stripslashes($_POST['username']));
$pass = mysql_real_escape_string(stripslashes($_POST['password']));
$result = mysql_query("SELECT user, pass FROM mcfruse WHERE user='$username'")or die(mysql_error());
$row=mysql_fetch_array($result);
if(mysql_num_rows($result)>0)
{
if(strcmp($row['pass'],$pass)==0)
{
echo "yes";
$_SESSION['name']=$username;
}
else
echo "no";
}
else
echo "no";

使用firebug时我的HTML说
是
所以yes是echo'ed,这意味着它通过了正确的pwd并且它验证了,但它仍然说"登录详细信息很糟糕"并且没有将我重定向到eindex.php
eindex.php
<?php
session_start();
if(!isset($_SESSION['name']))
header("Location:../index.php");
//if logout then destroy the session and redirect the user
if(isset($_GET['logout']))
{
session_destroy();
header("Location:../index.php");
}
require("../mcfrdb.php");
?>

我已经检查了几次代码,但找不到任何东西.所有回复和任何帮助表示赞赏.非常感谢.
编辑:甚至添加md5 pwd哈希(从此代码中省略)我仍然得到"是",当我回显用户名和哈希,他们是机器人匹配,但会话仍未设置,但不重定向我.on if($ .trim(data)=='yes')
你的ejaxlog.php
回报yes
?你确定吗?尝试添加alert(data)
orconsole.log(data)
看看它返回什么。似乎您的脚本不返回yes
或不仅返回yes
(可能是一些错误?)。显然,您没有被重定向,因为您的 JavaScript 接收到不合适的字符串,因此它不会重定向您。再次尝试记录/警报脚本返回的数据。或者安装 FireBug for FireFox 之类的东西来查看 JavaScript 完成的所有请求。
