重定向提交按钮(登录页面)


Redirect submit button (Login page)

我有一个小问题。我有一个登录框与提交按钮,但我不能重定向到另一个页面。我插入电子邮件和密码,但它不工作,它只是停留在第一页。我能做什么?

我用这个:

header("Location: home.php");
下面是我的代码:
<?php session_start();
    include_once 'dbconnect.php';
    if(isset($_SESSION['user'])!="") {
        header("Location: home.php");
    }
    if(isset($_POST['btn-login'])) {
    $email = mysql_real_escape_string($_POST['email']);
    $upass = mysql_real_escape_string($_POST['pass']);
    $res=mysql_query("SELECT * FROM users WHERE email='$email'");
    $row=mysql_fetch_array($res);
    if($row['password']==md5($upass)) {
        $_SESSION['user'] = $row['user_id'];
        header("Location: home.php");
    } else {
?>
<script>alert('wrong details');</script>
<?php } } ?> 

首先isset($_SESSION['user'])返回布尔值:truefalse而不是",因此必须使用if(isset($_SESSION['user']) && $_SESSION['user']!="")

第二,你所有的mysql_*功能都被弃用了。

<?php session_start();
include_once 'dbconnect.php';
if(isset($_SESSION['user']) && $_SESSION['user']!='') {
    header("Location: home.php");
}
if(isset($_POST['btn-login'])) {
  $email = mysql_real_escape_string($_POST['email']);
  $upass = mysql_real_escape_string($_POST['pass']);
  $res=mysql_query("SELECT * FROM users WHERE email='$email'");
  $row=mysql_fetch_array($res);
  $_SESSION['user']='we have pw';
  if( $row['password']==md5($upass) ) {
      $_SESSION['user'] = $row['user_id'];
      header("Location: home.php");
} else {?>
      <script>alert('wrong details');</script>

你的密码是否被转换为md5 ??这一行应该是问题所在。注意:如果这是你的home.php,那么它会重定向一整天

修改

header("Location: home.php");

echo "<script>window.location.assign("home.php")</script>";

试试这个:

<?php session_start();
include_once 'dbconnect.php';
if(isset($_SESSION['user'])!="") {
    header("Location: home.php");
}
if(isset($_POST['btn-login'])) {
$email = mysql_real_escape_string($_POST['email']);
$upass = mysql_real_escape_string($_POST['pass']);
$res=mysql_query("SELECT * FROM users WHERE email='$email' AND password= 'md5($upass)' ");
$row=mysql_fetch_array($res);
if($row) {
    $_SESSION['user'] = $row['user_id'];
    header("Location: home.php");
} else {
?>
 <script>alert('wrong details');</script>

<?php }} ?>
