display my feeds from facebook on my webpage with javascript api? - facebook

Question

Im trying to get all the feed from my facebook page whit the javascript api.
Does anybody have a working example?
I have tryed but I cant get it right, I can get photos from albums, but I cant get the feeds and I dont know what Im doing wrong.
Any input really appreciated. Thanks!
I have this code:
Edit
OK, I have the code inside the init code like below and it doesnt work, it is not executing the code and I get no errors:
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '<%=facebookAppId%>', // App ID
channelUrl : 'www.mypage.se/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
oauth : true
});
// get the wall - feed
var page_id = '<%=facebookPageId%>';
FB.api('/' + page_id, {fields: 'access_token'}, function(resp2) {
if(resp2.access_token) {
alert(resp2.access_token);
FB.api('/page id/feed?access_token='+resp2.access_token, function(response) {
var ul = document.getElementById('feed');
for (var i=0, l=response.data.length; i<l; i++) {
var
feed = response.data[i],
li = document.createElement('li'),
a = document.createElement('a');
a.innerHTML = feed.message;
a.href = feed.link;
li.appendChild(a);
ul.appendChild(li);
}
});
}
});
};//end window.fbAsyncInit
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
So why can I have for example:
FB.api('/facebook id', function(response) {
alert('Your name is ' + response.name);
});
inside the init code and not the other code?
I would still need some structure help writing the callbacks out on the page so it looks good as it does on facebook.
I like to write out "message, picture, link, name" and maybe something else?
As I test to get the messages in this example and some of the callback is displayed as "undefined" on the page? Does that mean that the message doesnt have a value when I get it?
If so how can I not write out emty values - undefined ones?
Thanks!
UPDATE:
If I use this code then it reads the feed, but only if Im logged in to Facebook?
Im starting to get confused, since I think that the above code should work:
I first ask for the access token in the first call, and when I get the access token, then using it in the second call, what Im I doing wrong?
FB.api('/my userid or pageid/feed?access_token=the acces token that I get from the Graph API Explorer', {limit:5} , function(response){
if (response && response.data && response.data.length){
alert(response.message);
var ul = document.getElementById('feed');
for (var j=0; j<response.data.length; j++){
var feed = response.data[j],
li = document.createElement('li'),
a = document.createElement('a');
a.innerHTML = feed.message;
a.href = feed.link;
li.appendChild(a);
ul.appendChild(li);
}
}
});
I get a couple of undefined responses, how can I not write them out on the page?
How can I get the above code to work even if the user that visit the webpage is not logged in to facebook?
I make other calls that gets the photos of an album with no problem displaying them on the webpage, I dont understand why this is different?
If I want to set this up for a customer(when its finished) what are the steps I need to take? Getting a bit confused... :-)
I would like to get the message, picture, likes etc with the call
and display it like it is on the feed-wall, any suggestions here?
Ok, finally I got it working :-)
I got the right acces token and now I can display the feeds.
I got the right token here:
https://graph.facebook.com/oauth/access_token?client_id=myapp_id&client_secret=myapp_secret&grant_type=client_credentials
And now I can use the below code both for getting user feeds and page feeds, just changing the page_id!
var page_id = '<%=facebookPageId%>';
var pageaccessToken='xxxxxxxxxxxxxxxxxxxxxxxxxx';
FB.api('/' + page_id + '/feed?access_token='+ pageaccessToken, {limit:5} , function(response){
if (response && response.data && response.data.length){
var ul = document.getElementById('pagefeed');
for (var j=0; j<response.data.length; j++){
var feed = response.data[j],
li = document.createElement('li'),
a = document.createElement('a');
a.innerHTML = feed.message;
a.href = feed.link;
li.appendChild(a);
ul.appendChild(li);
}
}
});
Ok, now it works, but I get the undefined in the response?
What is causing this, is it because it is a empty value that I get in the response?
What can I do so it is not displayed on the page?

Answer 1

I don't understand what it is you're trying to do, I have the feeling though that you took the wrong path..
Let's start with the fact that you don't need any special permission or a page access token to query for the page feed, it's public and so all you need (quoted from the docs) is: "any valid access_token or user access_token".
Which means that if a user authorized your application, you then acquired an access token for him and can get any page feed.
For example try the southpark page feed in the Graph API Explorer.
Another issue is that asking the user for the "manage_pages" permission and then asking the graph api for the access token of your own app would not work. When a user grants your app to manage his pages that's exactly what you get, the permissions to his pages, and so this request for example: /southpark?feilds=access_token won't get you the token since you are not the admin of this page (even if you grant the app with the "manage_pages" permission).
Last thing is the use of window.onload, which in your situation just does not address the problem.
You don't want to execute that code when the window is loaded but when the facebook sdk is loaded and intialized. That's why facebook tells you to use the fbAsyncInit event.
The code you had before the window.onload is the correct form, what exactly do you mean when you say "it didn't work"? Did you get any errors? It did not get executed?
Edit
From what I understand you want to display the content of a facebook Page feed in your website.
As I already told you, all you need in order to get the feed of a page is an active access token ("any valid access_token or user access_token").
If you follow the Authentication doc, the App Login section you'll see that you can issue an access token for your facebook app. With that token you can then get the feed of ANY PAGE you want on the server side.
