Default External Site login from application (salt, MD5 issue)

Hi all,

I've been pulling my hair out trying to figure out what's wrong. I think my method is wrong.

The code works fine with plain text passwords but I can't seem to figure out how to use salt!

PHP Code:
<?php

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

if (
selectFromDB() == md5(md5($password).$count['salt'])) {
   echo 
"Accept";
} else {
   echo 
"Denied";
}

function 
selectFromDB() {
    
    global 
$username;
    
//Database service vars
    
$databasehost "localhost";
    
$databasename "nes";
    
$databasetable "test";
    
$databaseusername ="root";
    
$databasepassword "password";

    
$con mysql_connect($databasehost,$databaseusername,$databasepassword) or die(mysql_error());
        
mysql_select_db($databasename) or die(mysql_error());

    
    
$query "SELECT password,salt FROM user WHERE username='$username'";
    
    
$result mysql_query($query);
    
$count mysql_num_rows($result);

    if (
$count)
    {
        
$output mysql_result($result0);        
        return 
$output;
    }
    else
    {
        return 
"0";
    }
    
mysql_free_result($result);
    
mysql_close($con);
}

?>
Thanks for your time
