Question

我希望将用户重定向到特定用户页面。我有一张桌子用户名密码重定向

我似乎无法编写重定向代码，以便windows.location重定向到数据库中为登录的特定用户的链接。

dataconnect.php

 <?PHP
    @mysql_connect("localhost","root","")
    or die("could not connect to mysql");
    @mysql_select_db("login")or die("no database");
    ?>

的index.php

$(function() {

   }, 5000, function(){

$(".sign_b_btn").live("click",function() {
var u=$("#u").val();
var p=$("#p").val();
if(u==""){
$("#u").css("border-color","red");

$(".error").show().html("Please enter your password.");
$("#p").css("border-color","red");

connect.php

<?PHP

//Get posted values from form
$u=$_POST['u'];
$p=$_POST['p'];

//Strip slashes
$u = stripslashes($u);
$p = stripslashes($p);

//Strip tags 
$u = strip_tags($u);
$p = strip_tags($p);

$p=md5($p);
$check = mysql_query("SELECT * FROM user WHERE user ='$u' 
AND pass='$p'")or die(mysql_error());
$check = mysql_num_rows($check);
if($check !== "0"){
$results = mysql_query("SELECT * FROM user WHERE user ='$u'") or die(mysql_error());
while ($row = mysql_fetch_assoc($results)) {
    $user=$row['user'];
    session_register('user'); 
    $_SESSION['user'] = $user;
echo"1";
} 
}
?>

Answer 1

这里我编辑了我的帖子试试这个............

while ($row = mysql_fetch_assoc($results)) {
$link=$row['redirect'];
} 
header('Location: "$link"');

Answer 2

在你的jQuery中，你发布到login_php.php。您的意思是发布到connect.php吗？

无论哪种方式，您可能想要做的只是返回您想要重定向到的链接而不是1，如果请求为空，您将继续执行您正在做的事情（投掷和错误）如果它不是空的，你将有一个有用的值。

尝试将connect.php更新为：

<?PHP 
include('dataconnect.php');//Your connection to your database

//Get posted values from form
$u=$_POST['u'];
$p=$_POST['p'];

//Strip slashes
$u = stripslashes($u);
$p = stripslashes($p);

//Strip tags 
$u = strip_tags($u);
$p = strip_tags($p);

$p=md5($p);
$check = mysql_query("SELECT * FROM user WHERE user ='$u' 
AND pass='$p'")or die(mysql_error());
$check = mysql_num_rows($check);
if($check !== "0"){
$results = mysql_query("SELECT user, redirect FROM user WHERE user ='$u'") or die(mysql_error());
while ($row = mysql_fetch_assoc($results)) {
    $user=$row['user'];
    session_register('user'); 
    $_SESSION['user'] = $user;
    echo $row['redirect'];
} 
}
?>

这假设您的重定向列位于users表中。如果是这种情况，那么它应该将用户的重定向值返回给jQuery ajax请求者。然后你可以在else if的ajax回调函数的Index.php语句中使用它：

else if(html != ''){
var redirect_url = html;
$(".error").fadeOut(1000);
$("#u").css("border-color","#606060");
$("#un").css("color","#333333");
$("#p").css("border-color","#606060");
$("#up").css("color","#333333");
$(".center").animate({
   opacity: 0.25,
   left: '+=900',
   height: 'toggle'
   }, 5000, function() {
$(".done").slideDown(200).html("Welcome "+u); 
setTimeout(function(){
var u=$("#u").val("");
var p=$("#p").val(""); 

window.location=redirect_url;
}, 5000);
});
}

除了您的问题，我还强烈建议您查看SQL注入。就目前而言，connect.php脚本容易受到SQL注入的影响。基本上，您需要转义$u和$p个变量。使用类似mysql_real_escape_string的内容来执行此操作。
