login - verify password

[FutileSoul]

I put my username and password in the database (password using MD5).  In the DB table (users) i have 3 columns, (id, username, pass) when I try to login using the following login page it says that the password is incorrect.

 

please help

 

i have the following code

 

<?php

// Connects to your Database 
mysql_connect("dbhost", "username", "password") or die(mysql_error()); 
mysql_select_db("dbname") or die(mysql_error()); 


//Checks if there is a login cookie

if(isset($_COOKIE['ID_my_site']))


//if there is, it logs you in and directs you to the members page
{ 
$username = $_COOKIE['ID_my_site']; 
$pass = $_COOKIE['Key_my_site'];

$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());

while($info = mysql_fetch_array( $check )) 	
	{

	if ($pass != $info['pass']) 
		{

		}

	else
		{
		header("Location: members.php");

		}

	}

}


//if the login form is submitted

if (isset($_POST['submit'])) { // if form has been submitted


// makes sure they filled it in

if(!$_POST['username'] | !$_POST['pass']) {
	die('You did not fill in a required field.');
}

// checks it against the database

if (!get_magic_quotes_gpc()) {
	$_POST['email'] = addslashes($_POST['email']);
}

$check = mysql_query("SELECT * FROM users WHERE username = '".$_POST['username']."'")or die(mysql_error());

//Gives error if user dosen't exist

$check2 = mysql_num_rows($check);
if ($check2 == 0) {
	die('That user does not exist in our database. <a href=registration.php>Click Here to Register</a>');
			}


while($info = mysql_fetch_array( $check )) 	
{

$_POST['pass'] = stripslashes($_POST['pass']);
$info['pass'] = stripslashes($info['pass']);
$_POST['pass'] = md5($_POST['pass']);

//gives error if the password is wrong

if ($_POST['pass'] != $info['pass']) {
	die('Incorrect password, please try again.');
}

else
{
// if login is ok then we add a cookie 

$_POST['username'] = stripslashes($_POST['username']);


$hour = time() + 3600; 
setcookie(ID_my_site, $_POST['username'], $hour);
setcookie(Key_my_site, $_POST['pass'], $hour);	

//then redirect them to the members area
header("Location: members.php");
}

}

} else {	

// if they are not logged in
