Question

我正在开发一款应用。但是登录系统有问题。我想将用户重定向到（http://localhost/Media/Index.php#Home），如果他们正确登录的话。但它现在似乎不起作用。当我输入登录信息时，它只是重新加载，没有任何反应。请帮忙！

<?php include ("inc/scripts/mysql_connect.inc.php"); ?>
<?php
session_start(); //Start session
//Check if user is logged in or not
if (isset($_SESSION['user_login'])) {
$user = $_SESSION["user_login"];
 }
else {
$user = ""; //Do nothing
//echo"Sorry but your are not logged in!!!!!!!!!!!!!!"; 
}
?>
<?php
//Login Script
//user Login code
//Check user info when user inputs login information
if (isset($_POST['user_login']) && isset($_POST['password_login']) )
{
//filters input info
$user_login = preg_replace('#[^A-Za-z0-9)]#i','', $_POST['user_login']);//filters everything but numbers and letters
$password_login = preg_replace('#[^A-Za-z0-9)]#i','', $_POST['password_login']);//filters everything but numbers and letters
$password_login_md5 = md5($password_login); // encrypt password input because password in database is already encrypted in md5
//use Binary for case sensitive option
$sql = mysqli_query($con, "SELECT * FROM users WHERE BINARY username= BINARY'$user_login' AND password='$password_login_md5' AND closed='no' LIMIT 1"); //query
//check for existence if user exists
$userCount = mysqli_num_rows($sql); //Count the number of rows returned
//if username exists start session
if($userCount==1)
{
while($row = mysqli_fetch_array($sql)) //fecthing the row to display information
{
$id = $row["id"]; // store user id into variable called $id
}
$_SESSION["id"] = $id;  
$_SESSION['user_login'] = $user_login;
$_SESSION["password_login"] = $password_login;
header("Location: Index.php#Home");//WE WANT USER TO ACCESS THE #HOME PAGE IF THEY ONLY LOGGED IN SUCCESSFULLY
//exit("<meta http-equiv=\"refresh\" content=\"0\">");              
}
else{
    //echo"That information is incorrect, Please try again!";
}
exit(); 
}
?>

正如我在上面的评论中所提到的，我不认为你可以在这里使用重定向，因为重定向是在加载页面上的HTML之前执行的，因此当你试图重定向时，id不存在它。但是，您可以使用javascript和.scrollTop来执行此操作。

将此代码放在页面底部：

<?php
    if (isset($_SESSION['user_login']))
    {
        echo '<script>
                 var x = document.getElementById('Home').scrollTop;
                 document.body.scrollTop = x;
              </script>';
    }
?>

Php #home页面没有重定向
