Everyone keeps asking how I did the IconBuffet Stamps page. Here is the code. It has a couple little extras in there because I was planning on adding a “total possible points” calculation, but it seemed useless because “possible points” requires as many diamond deliveries as you can, and let’s face it…those are hard to make.

 
function data_encode($data, $keyprefix = "", $keypostfix = "") {
    assert( is_array($data) );
    $vars=null;
    foreach($data as $key=>$value) {
        if (is_array($value)) {
            $vars .= data_encode($value, $keyprefix.$key.$keypostfix.urlencode("["), urlencode("]"));
        }    else {
            $vars .= $keyprefix.$key.$keypostfix."=".urlencode($value)."&";
        }
    }
    return substr($vars, 0, -1);
}
if (isset($_REQUEST['username'], $_REQUEST['password'])) {
 
    $post_data = array('email'=>$_REQUEST['username'], 'password'=>$_REQUEST['password']);
