[SOLVED] Login script help

[echocpt]

Hi, basicly i have a login script that i have already used for one of my sites and it worked fine but when i moved it over to a new site it is'nt working. Could someone please point me in the correct direction? Thanks alot.

 

This is the login php code for "login2.php":

<?php 
// login2.php

session_start();
include("connection.php");


if(isset($_POST['submit'])) {
if(empty($_POST['username']) || empty($_POST['password'])) {
	header("Location: login.php");
	exit;
}

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

$password = md5($password);


$query = "SELECT username,password 
		  FROM	 `user`
		  WHERE	 username='$username'";

$result = mysql_query($query);
if(!$result) { 

	echo "The query failed " . mysql_error();
} else {

	$row = mysql_fetch_object($result);

	if($row->password != $password) {
	echo "The password is fucked" . mysql_error();
	}

	$_SESSION['username'] = $username;
	$_SESSION['sid'] = session_id(); 
	$_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];

	header("Location: welcome.php");
	exit;
}
}
?>

 

This is the html form code:

<form id="form6" name="form6" method="post" action="login2.php">
					<table width="638" border="0" cellspacing="0" cellpadding="0">
						<tr>
							<td width="190">Username:</td>
							<td width="449"><label>
							<input name="username" type="text" class="area" id="username" value="" />
							</label></td>
						</tr>
						<tr>
							<td> </td>
							<td> </td>
						</tr>
						<tr>
							<td>Password:</td>
							<td><label>
							<input name="password" type="password" class="area" id="password" value="" />
                                
							</label></td>
						</tr>
						<tr>
							<td> </td>
							<td> </td>
						</tr>
						<tr>
							<td> </td>
							<td><label>
							  <input type="submit" name="submit" id="submit" value="Login" /></form>

 

Thanks for any help.

Sorry for the double post but it seems u can't edit posts for some crazy reason.

 

Completly forgot to post the error message displayed which was:

Warning: Cannot modify header information - headers already sent by (output started at /home/zerosite/public_html/ccf/redo/pages/login2.php:39) in /home/zerosite/public_html/ccf/redo/pages/login2.php on line 49

Thanks

would help to know what was on line 39, and whats in the includes like login.php. Check you are not echoing information out to the browser before you are setting cookies.
