Problem in Post method

Dear all,

I have a problem in Post method

the page go to the same page rather than going to another page

here is the code of the 1st page:

<?php

// Get these from http://developers.facebook.com
$api_key = 'xxxx';
$secret  = 'xxxx';

// Names and links
//$app_name = "quiz_taker";
//$app_url = "apps.facebook.com/quiz_taker/"; // Assumes application is at http://apps.facebook.com/app-url/
//$invite_href = "quiz.php"; // Rename this as needed


require_once ('../facebook-platform/php/facebook.php');

$facebook = new Facebook($api_key, $secret);
$facebook->require_frame();
$user = $facebook->require_login();
		
$con = mysql_connect("localhost","mooledco_user","123456");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

// Create table
mysql_select_db("mooledco_quiz", $con);
$sql = "select * from question";

$result = mysql_query($sql);
// Execute query
$i = 1;
//echo'<fb:editor-custom >';
echo '<form action="invite.php" method="post" id="quiz">';

while($row = mysql_fetch_array($result))
  {
  echo $i.".".$row['description']."<br>";

  $select = "select description from Answer where question_ID=".$row['Q_ID'];

  $res = mysql_query($select);

  while ($r = mysql_fetch_array($res))
  {
	echo "<input type='radio' name='answer".$i."' value='".$r['description']."' />";
	
	echo $r['description'];
	echo "<br/>";
	
  }
  echo "<br />";
  $i++;
  }

echo '<input type="submit" value="Submit" />'; 
echo "</form>";
//echo '</fb:editor-custom>'; // end of echo

mysql_close($con);

?>

PHP:

and Here's the code of the second page:

<?php
require_once ('../facebook-platform/php/facebook.php');

$appapikey = 'xxxx';
$appsecret = 'xxxx';
// Connect to Facebook, retrieve user
$facebook = new Facebook($appapikey, $appsecret);
$user = $facebook->require_login();

// Get a list of friends who are existing users of the app
$app_users=$facebook->api_client->friends_getAppUsers();
if ($app_users) {
for ($i=0;$i<count($app_users); $i++ ) {
if ($i != 0){
$exclude_list .= ",";
}
$exclude_list .= $app_users[$i]["uid"];
}
}
$ref_user = urlencode("&refuid=".$user);
$invite_text = <<<FBML
You’ve been invited to sign up with the grandest app in FacebookLand: F8 For
Dummies!
<fb:name uid="$user" firstnameonly="true"/> selfishly wants you to add F8 For
Dummies! so that <fb:pronoun uid="$user"/> can get credit for it.
118 Part II: Poking the API
<fb:req-choice
url="http://www.facebook.com/add.php?api_key=$appapikey&next=$ref_
user"label="Sign up and become a Dummy!" />
FBML;
?>
<fb:request-form action="http://apps.facebook.com/dummies//index.php?c=skipped"
method="POST" invite="true" type="Dummies"
content="<?=htmlentities($invite_text)?>">
<fb:multi-friend-selector showborder="false"actiontext="Invite your friends
to use F8 For Dummies." exclude_ids="<?=$exclude_list?>" />
</fb:request-form>

PHP:

What's the problem? I'm just using Facebook Library I think it's the problem?

Thank You in advance

 

i used to program using facebook library.. as far as i remember using action="blah.php" will only send the post data.. they have dedicated functions to do redirection.
