Question

I’m trying to make a Facebook video application so users can have a video stored on my site displayed on their wall using Facebook Open Graph.

I’m using the below code for user login.

<script>
    window.fbAsyncInit = function() {
        FB.init({
            appId      : 'MYAPPID', // App ID
            status     : true, // check login status
            cookie     : true, // enable cookies to allow the server to access the session
            xfbml      : true  // parse XFBML
        });
    };

    // Load the SDK asynchronously
    (function(d){
        var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
        js = d.createElement('script'); js.id = id; js.async = true;
        js.src = "//connect.facebook.net/en_US/all.js";
        d.getElementsByTagName('head')[0].appendChild(js);
    }(document));
</script>

Now how do I implement the Watch action?

curl -F 'access_token=myaccesstoken' \
 -F 'movie=http://samples.ogp.me/453907197960619' \
    'https://graph.facebook.com/me/video.watches'

And this

curl 'https://graph.facebook.com/me/video.watches?access_token=myaccesstoken'

in PHP? And how can I get the access token of users?

Answer 1

To get the user access token in PHP SDK 3.1.1:

// Get the current access token
$access_token = $facebook->getAccessToken();

This tutorial will guide you through the key steps to build, test, and publish your first Open Graph application. We will build a sample recipe application that allows users to publish stories about cooking recipes. Before starting, please review the Open Graph Checklist which will not only help in your app design and planning, but will also help speed up the application review process.

Step 1: Create a Facebook applications. https://developers.facebook.com/docs/opengraph/tutorial/#create-app

Step 2: Authenticate users with the Login Button plugin. https://developers.facebook.com/docs/opengraph/tutorial/#authenticate

Step 3: Define Objects, Actions and Aggregations through the App Dashboard. https://developers.facebook.com/docs/opengraph/tutorial/#define

Step 4: Publish Actions for your users. https://developers.facebook.com/docs/opengraph/tutorial/#publish

Step 5: Add Social Plugins to your application. https://developers.facebook.com/docs/opengraph/tutorial/#plugins

EXAMPLE:

if ($user){
    $queries = array(

        array('method' => 'POST', 'relative_url' => '/me/anotherfeed:view?feed=http://anotherfeed.com/')
        // Any other API calls needed, this is a batch request for performance.
    );

    try {
        $postResponseA = $facebook->api('?batch='.json_encode($queries), 'POST');
    }
    catch (FacebookApiException $e) {
        //echo 'AF error: '.$e.'';
    }
    // Returns the id of posted actions if true.
    $actions = json_decode($postResponseA[0][body], true);
