How to get page to redirect after login

Reza Ruslan

I'm trying to create a simple login page with php using session. when i want to access the index.php, the page successfully redirect to login page. then I put username and password based on the table in database. the problems arise when I press the submit button, username and pssword is accepted but the page is still in login page (not redirect to defined page in the code.

how this can happen? Is there something wrong in the code that I created? or something wrong with my php.ini settings? ANYONE please help me..

for the detail, the following is the code that I created.

1. login.php - the login form that submit to checklogin.php

Expand|Select|Wrap|Line Numbers

 
<html>

<head>

<title>Login</title>

</head>

<body>

<form name="form1" method="post" action="checklogin.php">

<dl>

    <dt>Username</dt>

        <dd><input type="text" name="username"></dd>

    <dt>Password</dt>

        <dd><input type="password" name="password"></dd>

    <dt></dt>

        <dd><input type="submit" name="Submit" value="Login"</dd>

</dl>

</form>

</body>

</html>

2. checklogin.php - the page for check if username and password is correct or not

Expand|Select|Wrap|Line Numbers

 
<?php

session_start();

$server = "localhost";

$username = "root";

$password = "root";

$db_name = "ecommerce";

$db = mysql_connect($server,$username,$password) or DIE("connection failed !!");

mysql_select_db($db_name) or DIE("no database !!");

$login = mysql_query("select * from login where (username = '".$_POST['username']."') and (password = '".md5($_POST['password'])."')",$db);

$rowcount = mysql_num_rows($login);

if ($rowcount == 1){

    $_SESSION['username'] = $_POST['username'];

header("Location: index.php");

}

else

{

header("Location:login.php");

}

?>

3. index.php - the redirect page or the main page

Expand|Select|Wrap|Line Numbers

 
<?php

session_start();

if (!isset($_SESSION['username'])){

header("Location:login.php");

}

echo"login success, this is index.php page<br>";

echo"welcome, user<br>";

echo"<a href=\"logout.php\">logout</a>";

?>

I hope there is someone who can help provide a solution for me. thanks before.

If the session is working, then it's likely not an issue with the output buffer. The problem is likely in your use of the "Location" header. The "Location" header requires a space after the colon (like all headers) and requires an absolute path, not a relative path. Using a relative path puts you at the risk of your header not working, as the browser isn't required to serve your malformed header "intelligently. "

Session fixation idea

by: Gordon Burditt | last post by:

I had this idea about preventing session fixation, and I'm wondering what anyone else thinks about it. The idea is, essentially, don't allow session ids that YOUR PHP didn't generate (and aren't yet expired) to log in. That way if someone sticks a made-up session ID on a URL, it won't matter, unless it happens to correspond to an active...
