"AND password = (PASSWORD('" . $_POST['password'] . "'));";
$result = mysql_query($query)
or die(mysql_error());
if (mysql_num_rows($result) == 1)
{
$_SESSION['user_logged'] = $_POST['username'];
$_SESSION['user_password'] = $_POST['password'];
header ("Refresh: 5; URL=" . $_POST['redirect'] . "");
echo "You are being redirected to your original page request!<br>";
echo "(If your browser doesn't support this, <a href=\"" .
$_POST['redirect']. "\">click here</a>)";

Re: login script problem
How are you storing your passwords? It seems like it uses MySQL's PASSWORD hash scheme to check against the passwords.
Please post an example row from your MySQL table. An example means don't post your everyday password, fyi ;).

Re: login script problem
i would remove you email from your post if i were you. Your inbox will be spammed
Also, i made some changes to you code, mostly organized it. But you might want to try my code and see if it works
PHP Code:
<?php
session_start();
include "conn.inc.php";
if (isset($_POST['submit']))
{
$query = "SELECT username, password FROM users WHERE username='{$_POST['username']}' AND password=PASSWORD('{$_POST['password']}')";
$result = mysql_query($query) or die(mysql_error());
if (mysql_num_rows($result) == 1)
{
$_SESSION['user_logged'] = $_POST['username'];
$_SESSION['user_password'] = $_POST['password'];
header("Refresh: 5; URL='{$_POST['redirect']}'");
echo "You are being redirected to your original page request!<br>";
echo "(If your browser doesn't support this, <a href='{$_POST['redirect']}'>click here</a>)";
}
else
{
?>
<html>
<head>
<title>user Login</title>

<input type="submit" name="submit" value="Login">
</form>
</fieldset>
</body>
</html>
<?php }
}
else
{
if(isset($_GET['redirect']))
{
$redirect = $_GET['redirect'];
}
else
{
$redirect="index.php";
}
?>
<html>
<head>
<title>User Login</title>

<body>
<fieldset>
Login below by supplying your username/password...<br>
Or <a href="register.php">click here</a> to register.<br><br>
<form action="user_login.php" method="post">
<input type="hidden" name="redirect" value="<? echo $redirect; ?>">
Username: <input type="text" name="username" ><br>
Password: <input type="password" name="password" ><br><br>
<input type="submit" name="submit" value="Login">

</html>
<?php
}
?>
Also might want to take a look at mysql_real_escape_string()

Re: login script problem
Not really related to the question, but using $_POST values directly in your query is prone to MySQL injection.
Edit: Nvm, missed what dclam posted.
