Good afternoon guys hoping someone can help me with this question I have. I'm trying to add lastFM user.getRecentTracks to the postbit_legacy on our forum but can't seem to get it working. I'm calling it from an external .php file like so

<?php


$apikey = "*API KEY is here*";
$secret = "*SECRET KEY is here*";
$token = $_REQUEST['token'];
$artist = $_GET['artist'];
$track = $_GET['track'];
$key = $_COOKIE["userkey"]; // check if we have a session key saved in the cookies
if ($token == "")
{
echo "<a href = \"http://www.last.fm/api/auth/?api_key="*API KEY*">Authenticate</a>";
}
else
{
if ($key == "") // if there's no session key in the cookies, generate one and save it
{
$apisig = md5("api_key".$apikey."method"."auth.getSession"."token".$token.$secret);
$data = file_get_contents("http://ws.audioscrobbler.com/2.0/?method=auth.getSession&api_key=$apikey&token=$token&api_sig=$apisig&format=json");
$data = json_decode($data,true);
$name = $data['session']['name'];
$key = $data['session']['key'];
setcookie("userkey", $key, time()+3600);
}
$timestamp = date("U");
$apiSig = md5("api_key".$apikey."artist[0]".$artist."methodtrack.scrobblesk".$key."timestamp[0]".$timestamp."track[0]".$track.$secret);
$postvars = "method=track.scrobble&api_key=$apikey&artist[0]=$artist&sk=$key&track[0]=$track&timestamp[0]=$timestamp&format=json&api_sig=$apiSig";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://ws.audioscrobbler.com/2.0/");
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postvars);
$data = curl_exec ($ch);
curl_close ($ch); 
}
?>

I tested it on one skin and it seemed to work but then suddenly stopped


I've called the the PHP file on the skin by doing the following

<div align="center"><vb:if condition="$post['field55']">
<div class="eti_postbit"><iframe src="http://ourwebsitename/LASTFM/scrob.php?name={vb:raw post.field55}" style="border: none; width: 198px; height: 44px;margin-left: -5px;"></iframe></div>
</vb:if></div>

Is there a better way of doing this. Any help is appreciated
