Facebook new javascript sdk- uploading photos with it!

I am trying to upload a photo to facebook album with this javaascript code.

FB.api('/me/photos', 'post', {    access_token: GetToken(),
                            name: 'uploaded photo',
                            source: '@http://example.com/example.jpg' }, 
            function(response) {
                if (!response || response.error) {
                    alert('Error occured ' + response.error开发者_开发百科.message);
                } else {
                    alert('Post Id: ' + response.id);
                }
            });

Can someone help me with this code. This code is not returning anything.

Assuming you want to do this in pure JavaScript/JQuery - you'll need to use an iframe as the target of a form, there is a caveat - you will not be able to use the return data (the ID / success of the call) because of the same origin policy.

First create a form that will hold the file input and any other variables you wish to set:

<form id="upload-photo-form">
    <input name="source" id="source" size="27" type="file" />
    <input name="message" id="message" type="text" value="message example please ignore" />
</form>

Here is the main function used which creates an iframe, points the form to use it, and then retrieves the latest photo from the album using FQL.

function fileUpload(form, action_url, div_id) {
    // Create an iframe 
    var iframe = document.createElement("iframe");
    iframe.setAttribute('id', "upload_iframe");
    iframe.setAttribute('name', "upload_iframe");
    iframe.setAttribute('width', "0px");
    iframe.setAttribute('height', "0px");
    iframe.setAttribute('border', "0");
    iframe.setAttribute('style', "width: 0; height: 0; border: none;");

    // Add to document.
    form.parentNode.appendChild(iframe);
    window.frames['upload_iframe'].name = "upload_iframe";

    iframeId = document.getElementById("upload_iframe");

    // Add event to detect when upload has finished
    var eventHandler = function () {

        if (iframeId.detachEvent)
        {
            iframeId.detachEvent("onload", eventHandler);
        }
        else
        {
            iframeId.removeEventListener("load", eventHandler, false);
        }

        setTimeout(function() {
            try
            {
                $('#upload_iframe').remove();
            } catch (e) {

            }
        }, 100);

        FB.api({
            method: 'fql.query',
            query: 'SELECT src_big,pid,caption,object_id FROM photo WHERE aid= "' + albumID + '" ORDER BY created DESC LIMIT 1'
            },
            function(response) {
                console.log(response);
            }
        );

    }

    if (iframeId.addEventListener)
        iframeId.addEventListener('load', eventHandler, true);
    if (iframeId.attachEvent)
        iframeId.attachEvent('onload', eventHandler);

    // Set properties of form...
    form.setAttribute('target', 'upload_iframe');
    form.setAttribute('action', action_url);
    form.setAttribute('method', 'post');
    form.setAttribute('enctype', 'multipart/form-data');
    form.setAttribute('encoding', 'multipart/form-data');

    // Submit the form...
    form.submit();

}   

At runtime you will presumably know the albumObjectID from a previous call, and have the access token from the session object that is returned by login or session onauthchange.

var url = 'https://graph.facebook.com/' + albumObjectID + '/photos?access_token=' +  accessToken;
fileUpload($('#upload-photo-form')[0], url, $('#upload-photo-div')[0]);`

Obviously this isn't production code, there are a few things you can do to improve it's reliability (like checking the width, height, caption & tags of the submitted image to the latest image). Checking the latest image before & after the attempted upload etc.

PS: Watch out for the albumObjectID vs albumID, they are different however both can be obtained using some simple FQL queries. (eg: SELECT aid, object_id, can_upload, name FROM album WHERE owner = me() AND name = "My Album Name")

Hope this helps.

You're not far from the right query.

first, make sure your initiating the js sdk, and requesting permissions to post.

then, your two fields are message and URL:

var data = array();
data['message'] = 'hello world';
data['url'] = 'http://google.com/moo.jpg';

FB.api('/me/photos', 'post', data, function(response){
    if (!response || response.error) {
        //alert('Error occurred');
    } else {
        //alert('Post ID: ' + response.id);
    }
}); 

// UPLOAD A LOCAL IMAGE FILE, BUT THIS CAN NOT BE DONE WITHOUT USER'S MANUAL OPERATION BECAUSE OF SECURITY REASONS
function fileUpload() {
  FB.api('/me/albums', function(response) {
    var album = response.data[0]; // Now, upload the image to first found album for easiness.
    var action_url = 'https://graph.facebook.com/' + album.id + '/photos?access_token=' +  accessToken;
    var form = document.getElementById('upload-photo-form');
    form.setAttribute('action', action_url);

    // This does not work because of security reasons. Choose the local file manually.
    // var file = document.getElementById('upload-photo-form-file');
    // file.setAttribute('value', "/Users/nseo/Desktop/test_title_03.gif")

    form.submit();
  });
}
// POST A IMAGE WITH DIALOG using FB.api
function postImage1() {
  var wallPost = {
    message: "Test to post a photo",
    picture: "http://www.photographyblogger.net/wp-content/uploads/2010/05/flower29.jpg"
  };
  FB.api('/me/feed', 'post', wallPost , function(response) {
    if (!response || response.error) {
      alert('Failure! ' + response.status + ' You may logout once and try again');
    } else {
      alert('Success! Post ID: ' + response);
    }
  });
}
