我正在使用应用程序。但是登录系统有问题。如果正确登录，我想将用户重定向到（http：//localhost/media/index.php#home）。但是目前似乎不起作用。当我键入登录信息时，它只是重新加载，什么也不会发生。请帮助！
<?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();
}

如上所述，我认为您无法在此处使用重定向，因为在加载页面上的HTML之前，将重定向执行，因此ID不在当您试图重定向到它时就存在。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>';
}
?>
