fb_friend.module invitations delivered, but do not work

So i make simething I hope it make in a good way :
Hook menu : one page for the redirection in canvas and one for callback ajax exclude id.

/*
* Implementation of Hook_menu
*/
function module_facebook_menu(){
  // User profile tabs
  $items['fb-invite/accept'] = array(
    'title' => 'accept',
    'page callback' => 'accept_facebook',
    // 'access callback' => 'invite_user_access',
    // 'access arguments' => arrays('accept invitation'),
       'page arguments' => array(1),
    'access arguments' => array('access content'),
    'weight' => 20,
        'type' => MENU_NORMAL_ITEM,
  );
 	$items['fb-invite/exclud_id'] = array(
    		'page callback' => 'exclud_id_facebook',
       'page arguments' => array(1),
        'access arguments' => array('access content'),
    		'type' => MENU_CALLBACK,
  	);
    return $items;
  }

/* Implementation of AJAXPage_callback()
 * Fonction qui renvoi en format json les id facebook à exclure.

*/  
  
function exclud_id_facebook(){
  //Si on est pas sur un appel js
	if (!$_POST['from_js'] && $_GET['example_token'] == drupal_get_token()) 
    {
		return t('Activer le javascript pour pouvoir inviter vos amis.');
		}
	elseif ($_POST['from_js'] && $_POST['example_token'] == drupal_get_token()) 
    {
    global $_fb, $_fb_app;
		$fbu = fb_facebook_user();
		if (!$fbu)
      {
		  drupal_json(t('erreur de connexion Facebook'));
			exit;
			}
		// Exclude users who have already installed.
    $rs = fb_fql_query($_fb, "SELECT uid FROM user WHERE has_added_app=1 and uid IN (SELECT uid2 FROM friend WHERE uid1 = $fbu)"); // FQL not SQL, no {curly_brackets}
		//EMERYA on ajoute la condition qu'il ne soit pas sur le site.

          }
        }

    // Set the text/javascript headers and
    // return the response in JSON format.
    drupal_json($exclude_ids);
    exit;
    }
  else 
    {
    drupal_json(t('Page not found'));
    exit;

    }
}

function accept_facebook(){

    //Object facebook et facebook api
    global $_fb, $_fb_app;
    		$fbu = fb_facebook_user();
   //Assuming the user has already authenticated the app
   // $user_id = $facebook->getUser();

   //get the request ids from the query parameter
   $request_ids = explode(',', $_REQUEST['request_ids']);

   //for each request_id, build the full_request_id and delete request  
   foreach ($request_ids as $request_id)
   {
   // $content.= ("request_id=".$request_id."<br>");
      $full_request_id = $request_id . '_' . $fbu;  
   // $content.= ("full_request_id=".$full_request_id."<br>");
  
      // try {
         $delete_success = $_fb->api("/$full_request_id",'DELETE');
      /*   if ($delete_success) {
             $content.= "Successfully deleted " . $full_request_id;}
         else {
             $content.= "Delete failed".$full_request_id;}*/
        // }          
      // catch (FacebookApiException $e) {
     // $content.="error".$e;}
    }
  $content.='<script type="text/javascript">
              top.window.location = \'http://yourForceUrl.com\';
            </script>';
  $content.=t('Vous allez être redirigé dans quelques secondes, merci de patienter.');
        // drupal_goto('http://pastasparty.com#TOP');
  return $content;
}

Here the javascript :

Drupal.behaviors.moduleFacebook = function(context) {
var fbInvite = $('#fb-invite-buton');
	fbInvite.click(function(event) 
    { 
    //Envlève le comportement du bouton car sinon il est lancé plusieurs fois
    fbInvite.unbind('click');
		//bind le comportement ajax du callback de la page
    event.preventDefault();

		// Perform the ajax request - the configurations
		// below can be modified to suit your needs:
		// http://docs.jquery.com/Ajax/jQuery.ajax#options
		$.ajax(
      {
		  type: "POST",
		  url: '/fb-invite/exclud_id',
		  data: {
			'from_js' : true,
			'example_token' : Drupal.settings.exampleToken
		  },
		  dataType: "json",
		  success: function (data)
        {
        // alert_r(data);
        excludeId='';
        if (typeof data!= 'undefined' &&     data.length >0) {
          for(var i=0;i<data.length;i++)
            {
            if(      excludeId!='')
                  excludeId+=',';
                  excludeId+=data[0];
            }
          }
              // alert_r(excludeId);
        // if (data.message) {
          // Remove any messages that are already there. It might
          // be good to abstract this a bit and make a function that
          // can remove the message div. You could then also bind a
          // a link titled "Close" to that function so that the user
          // can acknowledge the message and remove it.
          // $(".messages").remove();

          // The div where your messages div normally shows. This
          // example is from this particular custom theme - change
          // #content-column to the parent selector where your
          // .messages div displays in your theme. If you use the same
          // classes as Drupal, you end up with a nicely styled response
          // right where the user is accustomed to seeing messages.
          // $("#content-column").prepend('<div class="messages status">' + data.message + '</div>');
        // }
      //Construit la fenêtre de dialogue.
      FB.init({
        appId  : Drupal.settings.fb.fb_init_settings.appId
        });
      FB.ui({
        method: 'apprequests',
        message:'Invitation',
        exclude_ids :excludeId
                // data: thisurl
        }, requestCallback);
      },
    error: function (xmlhttp) {
      alert('An error occured: ' + xmlhttp.status);
		  }
		});
		  // alert(Drupal.settings.fb.fb_init_settings.appId);
	});
}

So you can have the dialogue form to call with this link

    $link=l(t('Invitez ses amis (avec personnes excluses)'), 'fb-invite/exclud_id', array(
      'query' => array(
        'example_token' => drupal_get_token()
      ),
      'attributes' => array(
        'id' => 'fb-invite-buton')  
      )
    );

I'm sorry for the comments and some wording in french.
This code need few review like token

I make test with the fb_friend module and it send a request but there some problème after :
-It doesn't make notification on Facebook (if you don't write canvas page in your Facebook application)
-The link wich apear in application have no effect, when you click on it there nothing happen
-I don't know if the Fb_friend module delete the request on facebook.api as facebool recommended "It is the Developers' responsibility to delete a Request once it has been accepted. For more information on how to delete a Request, please see the Deleting Requests documentation."
-Sometimes unlimited javascript load(don't load)

I will clean up the code if have got times (cause many work now)

* I report it on developper facebook, and they say" ok thank for report just FBML is depreciated." and close ticket with status "won't fix"

Just one question, have you fill in the https canvas url? cause for me not and when you click on link of invitation send (in facebook) it write that this url is not secure.
Try to clean the code tonight

mmmm I'm not sure to understand your last answer but for me it was a question for https for canvas page wich are obligatory on Facebook (cause with the new request dialog canvas page are obligatory). But I find the solution, the cloud services : http://devcenter.heroku.com/articles/facebook after to hav'nt the canvas page i force the redirection on it to my siteweb.
Have you try your request? I mean the request with fb_friend module? I try on your site and I can confirm that the links wich appear on Facebook have no effect, when you click nothing happen.
