re-directing a page?

[biscuitboy]

Hiya,

The following script I am using as a login screen and it seems to work fine apart from where the user is meant to be sent to the surname.php page. Have I written this incorrectly?

Any advice would be great

Best regards

Code:

<?php # Scrtipt 6.6 - viewresidents.php
if (isset($_GET['submit'])) {
require_once ('connect.php');

$message = NULL;
if (empty($_GET['username'])) {
$u = FALSE;
$message .= '<p>You forgot to enter your username!</p>';
} else {
$u = $_GET['username'];
}
if (empty($_GET['password'])) {
$p = FALSE;
$message .= '<p>You forgot to enter your password!</p>';
} else {
$p = $_GET['password'];
}

if ($u && $p) { //if everythings ok
$query = "SELECT first_name, user_id FROM users WHERE username='$u' AND password='$p'";
$result = mysql_query ($query);
$row = mysql_fetch_array ($result, MYSQL_NUM);
if ($row) {
//start session, register the values and redirect
session_start();
$_SESSION['first_name'] = $row[1];
$_SESSION['user_id'] = $row[0];
header ("location:

http://"

. $_SERVER['HTTP_HOST'] .
dirname($_SERVER['PHP_SELF']) . "/surname.php");

exit();

} else {
$message = '<p>The username and password entered do not match those on the file.</p>';
}
mysql_close();
} else {
$message .= '<p>Please try again.</p>';
}
}
$page_title = 'Login';
if (isset($message)) {
echo '<font color="red">',$message, '</font>';
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="GET">
<fieldset><legend>Enter your information in the form below:</legend>
<p><b>User Name:</b><input type="text" name="username" size="10" maxlength="20" value="<?php if (isset($_POST['username'])) echo $_POST['username']; ?>" /></p>
<p><b>Password:</b><input type="password" name="password" size="20" maxlength="20" /></p>
<div align="centre"><input type="submit" name="submit" value="Login" /></div>
</form><!-- end of form -->

looks ok. try debugging by creating the redirect href in a string and instead of redirecting echo the string to the screen. this is the most likely point of error.
