I am looking for a way to verify a users facebook id when posting user specific data using ajax. I want to be able to verify that a facebook user id is correct when posting data using ajax. The problem being, that if I post the facebook id as part of my ajax data, it can be edited in the javascript. I could make a graph call on the server side, but these are really slow, so I want to keep graph calls to a minimum. Preferably only calling it at the beginning. Can any suggest an efficient/secure method? In the end my solution was to grab the users facebook id via the php sdk and creating a hash

As instructed by this page , I include the SDK snippet into my page, except that since I don't have any Facebook APP and I was just trying to build a custom share button on my page, I leave parameter "app-id" as null .

However, it returns undefined , which means there is no response. What is wrong? Is this because I didn't assign a "app-id"? It depends on where you're calling getLoginStatus from and in what order. It needs to be inside your fbAsyncInit

I'm trying to understand how to use Facebook Connect (login) with jQuery Mobile and Phonegap Build , but as more I search about this information, more I get confused. I have already my app created on Facebook, and I have API number. I don't know if the best way is to call a PHP page (via ajax) where validates EMAIL + PASS via Facebook PHP SDK or Facebook SDK Javascript. For SDK JS I don't understand how to integrate it in my code (and I don't know if it's possible to test it by localhost). If someone could help me with this question... Update I tried @Dom suggestion, but when I click in the

I want to find out mutual friends between two random users using the facebook Graph API v2.2. I read through the documentation https://developers.facebook.com/docs/graph-api/reference/v2.2/user.context/mutual_friends It says, "A valid user access token with user_friends permission is required to view the mutual friends of other friends using the app. " Is there a way that I can find number and possibly names of all mutual friends between currentUser and User2, if they are not friends with each other? I referred to many other questions: Facebook Graph API 2.2 mutual friends => No answers How to

I've launched an application last week and have noticed since that in Chrome only the height of my canvas is not always adjusted. I've spent a bunch of hours looking at the issues and noticed that I get the following error - sometimes.

I'm using the Like Box social plugin ( https://developers.facebook.com/docs/reference/plugins/like-box/ ) and it works great. Problem is that I'm using it within a Rails 4 application with Turbolinks. Whenever I reload a page, the like box shows up. If I click on any link, the next page loads and the Like Box doesn't show up. I tried this already but didn't worked =/ http://reed.github.io/turbolinks-compatibility/facebook.html Any ideas on how to solve this problem? The link you have posted in original question is quite nice. It asks us to create three functions: 1) saveFacebookRoot: This is

I used to use this code: FB.getLoginStatus(function(response) { .... } But all of a sudden its not working, The callback doesn't fire. Oddly though, only with the android native browser (tested 4.0, 4.1). It works on iPhone, iPad, Chrome & Safari, including Chrome for android. I can't figure out why but its not restricted to my app. For instance I this app built by Sencha is no longer working either (I used it to base my code off): http://www.sencha.com/apps/jog-with-friends actual app url (Sencha Jog with friends): http://j.mp/senchajwf I have gone through a lot of posts on this issue and
