Facebook Requests ID(s) retrieve and delete - facebook

So I'm developing a small web app, that implements the Requests Dialog(User-to-User).
I'm able to send an invite and also successfully to save data as request id and user id. But when the user gets redirected to my app, after clicking on the request, i can't retrieve request id as shown here: https://developers.facebook.com/docs/requests/#deleting and then delete it.
But i see the request id in the address bar of the browser and it looks like this: http://apps.facebook.com/myownapp/?fb_source=request&request_ids=210655195715938 and REQUEST_URI is: /halten/?fb_source=request&request_ids=210655195715938
i tried with javascript:
function getMultipleRequests(requestIds) {
FB.api('', {
"ids": requestIds
}, function(response) {
console.log(response);
});
}​
or with php:
if(isset($_REQUEST['request_ids'])) {
$requestIDs = explode(',' , $_REQUEST['request_ids']);
foreach($requestIDs as $requestID) {
try {
$delete_success = $facebook->api('/' . $requestID, 'DELETE');
} catch(FacebookAPIException $e) {
error_log($e);
}
}
but the request_ids is always empty but my browser shows the request_id
So the question is how to handle the problem?
Thanks in advance

A User to User Request is actually notified to the user in 4 levels.
1) Jewel notification
2) Bookmarks counter
3) Right top counter
4) Weird location notification inside the app(I did not know what this was called sorry)
All of these request will take the user to the app but unfortunately on the Jewel notification(#1) request url will contain all the request IDs and the remaining will contain only a single request ID.
Say you send 4 requests (1,2,3,4)
#1 in url will have 1&2&3&4
#2,#3,#4 will have one of those depending on which notification you response to
Hope this makes sense and answers the question.

deleting facebook requests

The facebook docs here say "it is the Developers' responsibility to delete a Request once it has been accepted". As far as I understand, when someone sends a request to multiple users on facebook like this:
function sendRequestViaMultiFriendSelector() {
FB.ui({method: 'apprequests',
message: 'test message'
}, requestCallback);
}
only one request_id is returned via requestCallback() function.
Then, if I delete the request when someone accepts it, how would other users accept the deleted request?
when user comes following the app request, you can get request id's using
$_GET['request_ids']
then retrieve all the request ids with which you can call graph api to delete the corresponding requests like below:
if(isset($_GET['request_ids']))
{
$request_ids = $_GET['request_ids'];
}
$request_ids = explode(",", $request_ids);
foreach($request_ids as $request_id)
{
$full_request_id = $request_id."_".$fbid; //$fbid is current user facebook id
$facebook->api("$full_request_id","DELETE");
}
Check out the Request ID Format section of the FB request overview page.
The actual graph path for a request actually sent to specific user is "request-id"_"recipient-user-id".
you can access to facebook on mobile mode (m.faceook.com)
1-access the invitation panel
2-display all the invitations
3-open console mode in chrome
4-activate jquery by cpying and pasting all the jquery.min code into console
and excecute this script :
$("._54k8._56bs._56bt").trigger("click");
that will cancel or the invitation sent

How to get the data param in an app generated request for a facebook user

I am sending an app generated request to a user(already authorized the app) by calling the below function
function send_app_request(){
FB.api( "/" + '<USER-ID>' + "/apprequests", "POST", {
message: "Custom Request for you!",
data: "<REDIRECT-APP-URL>",
access_token: "<APP-ACCESS-TOKEN>"
}, function(response) {
console.log(response);
});
}
When a user clicks on the pop-up that appears beneath the app icon(with a red number) at the top right corner of the canvas, he gets redirected to the index page of the canvas with 'request_ids' as one of the parameters. How do I get/decode the 'data' parameter(contains a url) which i passed during the FB.api call(in the function above), so that I can redirect the user to a specific location(url) in my application.
I have seen this functionality in many applications, and I am "unable" to figure out how they are able to redirect the users to a specific location in their app, instead of the index page when the user clicks on the pop up.
The data is specific for that request you send to the user.
When the user clicks the requests and gets to your page (with the "request_ids" parameter) you should then get the data for the requests.
The url to get the requests from:
https://graph.facebook.com/USER_ID/apprequests
You will get a list of the requests and the data for each one (if such was sent).
You then need to delete the request for the user by issuing a request to:
https://graph.facebook.com/REQUEST_ID?method=delete
You can find a php example here: Upgrade to Requests 2.0

How to get ids of facebook invited friends by user in my asp.net4.0 web application

I am developing an ASP.NET application. I implemented Facebook JavaScript API in my application, for connect with Facebook and get FB friend list of user. I had done this successfully.
Now, I want to count how many friends are invited by user. Is it possible with facebook API. User can select multiple friends and i want to count how many friends selected and invited by user, Invited friends Id is bonus if We can get.
Please don't forget that facebook changed its Oauth settings for security reasons.
I'm also trying to get ids values after Send Invitation button clicked and page post back to
if (Request.Form["ids"] != null)
{
span1.InnerHtml = "ids";
//put success code here..
}
else
{
span1.InnerHtml = "oops no id";
}
if (Page.PreviousPage != null)
{
span1.InnerHtml = "ids";
//put success code here..
}
else
{
span1.InnerHtml = "oops no id";
}
but in this case program control always goes to else condition it means after page is post back form return null value.
Is there any way to get ids of invited friends.
Thanks.
If you using Facebook Requests to send invites (you really should, it's intended for this), the only way to get invited friends is via Facebook Requests Dialog callback:
FB.ui({method: 'apprequests', message: 'Whoa!'}, callback);
function callback(response){
// response.to now contain array of invited users ids
console.log('Invited friends ids', response.to);
if (response.request) {
console.log('Efficient Request id', response.request);
} else {
console.log('Requests Ids', response.request_ids);
}
}
There is no way to get request sent by user via Graph API or FQL, you only can get requests received by user. You may save all requests sent by your users and rely on this data if you need aggregated count of invitation sent...
Ok finally I resolve this issue and get invited friends ids..
As we know we use javascript sdk for FB connect so my solution is in concern of Java script:
Just make on change in your .js file where you put your facebook connect javascript code. Use Get or Request Method instead of Post Method in fb:request-form tag.
<script type="text/javascript>
var fbhtml = "<fb:serverFbml width=\"" + width_of_invitation_div + "\">
<script type=\"text/fbml\"><fb:fbml><fb:request-form action=" + window.location + " method="REQUEST" invite="true" type="" + type_of_fb_request_form + "" hold=" /><br mode="></fb:request-form></fb:fbml></script></fb:serverfbml>"
</script>
After invitation send to users selected friends you get ids[] in url.
you can get these ids through query string and split ids by comma(,) and store in array.
Hope this will help for other devs.

catching like/dislike in my canvas application

I added a like button to the canvas application page that actually configured to the facebook page of the application.
I would like that whenever a user pressed like or dislike on my page, a request will be sent to my server noticing it that the user liked or disliked the application page.
I can catch these events by using the following code:
FB.Event.subscribe('edge.create', function(response) {
alert('You liked the URL: ' + response);
});
FB.Event.subscribe('edge.remove', function(response) {
alert('You disliked the URL: ' + response);
});
I can just check if the response equals to my facebook application page.
the question is.. after I catched the like or dislike, how do i forward it to the server secure enough ? how can I send the request to the server without posting the facebook id as a post/get parameter?
i want to send it to the server in a way that the server will be able to fetch the facebook session information and fetch the userid from there, or any other secure way.
example:
if i'll just call http://mysite/liked_my_app?uid=4534534543
then a user notice this request and start sending liked_my_app with fake uids.
is there a way to prevent that somehow ?
thanks
Instead of using the UID of the user, forward the signed_request. Only you can decode signed requests coming from your application because of the app_secret you have to use to decode it.
Another possible solution (depending on what exactly you want to do when you confirm a like/dislike event) is to check at intervals your page/app like count - in a cron job for example. When a user likes your page/app you can retrieve his UID (possibly other information as well), and you can cross-reference the lists from the last cron job.

"Request Dialog" requestCallback when clicking Cancel or Close button

I am new into Facebook application development and also newbie about JavaScript and PHP programming.
I currently developing a Facebook application but currently stuck with Request Dialog window.
When the Request Dialog appears, I choose friends I want and then click "Send Requests", the requestCallback(response) are executed and friends who getting requests are notified as expected. But, If I click "Cancel" or the blue-colored close button, the requestCallback(response) is also executed but selected friends are not getting notified about the request.
Here is my code:
function requestCallback(response)
{
//console.log(response);
location.href='step2.php';
}
So, whether I click "Cancel" or close button, the script above are still executed (moving to page step2.php I specify.)
What I want is when the user clicking cancel button or close modal window button, the page stay at the same page.
Anyone know how to solve this problem?
Thanks!
You can just check what's inside the Facebook response object, because it won't be the same if requests have been sent or not !
Something like :
function requestCallback(response)
{
if(response && response.request_ids) {
// Here, requests have been sent, facebook gives you the ids of all requests
//console.log(response);
location.href='step2.php';
} else {
// No requests sent, you can do what you want (like...nothing, and stay on the page).
}
}
Or if you are using the new structure (Request 2.0 Efficient):
function requestCallback(response)
{
if(response && response.request) {
// Here, requests have been sent, facebook gives you the request and the array of recipients
//console.log(response);
location.href='step2.php';
} else {
// No requests sent, you can do what you want (like...nothing, and stay on the page).
}
}
Look at the structure of the response object to make your condition. The callback is fired even when you hit close in order to have the possibility to notice when your user quits the dialog. It's up to you to verify if he sent requests, and act like you want ! :)
Also, something important :
Facebook updated their request system a few weeks ago, making available "Requests 2.0" in your apps settings. It's turned off by default, but if you activate it, the structure of the response object when sending requests to people will change. So you'd have to update your condition in the callback !
