I developed a application in facebook, and it can be automatically to post something on the users' wall. But now I want to post only once per day, how can I do it?
When you do call api to publish something on his/her wall, also save it into DB and then check it before each API call
<?php
$uid = $facebook->getUID();
$publishes = mysql_query("SELECT * FROM publishes WHERE uid = ".$uid." AND time > ".(time()-60*60*24);
$publish = mysql_fetch_assoc($publishes);
if (!$publish['time'])
{
//call api and post a post to a wall
}

My problem is: When I post to page's wall some message with link it shows as Posted By Others, without link it shows normally in page timeline (Im group's admin ).
The same code posts to my timeline just fine:
I use AS3 library.
My permissions:
"publish_stream", "user_photos","publish_actions","manage_pages"
my post code:
var params:Object = new Object();
params.message = messageTextInput.text;
params.description = "description";
params.caption = "caption";
params.name = "name";
params.link = "http://www.ya.ru";
params.picture = "http://image.bayimg.com/cajchaado.jpg";
FacebookDesktop.api(page.id+"/feed", onCallApi, params, "POST"); //use POST to send data (as per Facebook documentation)
Facebook documentation says I can post either link or message, but it works just fine, except of showing in "Recent posts by others" ( please see attached screenshot ).
To post on a fanpage on behalf of itself (not the user), you have to use the page access token.
What happening is- when you make the call, the sdk uses the default token (user token), so the post is published on behalf of the user which is displayed in the "Recent Post by Others" section in the page.
Since you have requested for manage_pages already in your code, you can simply obtain the page access token with this call- /{page-id}?fields=access_token. Use this token with your current call just by adding the parameter access_token-
....
params.picture = "http://image.bayimg.com/cajchaado.jpg";
params.access_token = "{page-access-token}";
....
I want to post on my facebook friends wall using my facebook app. I have already set the sufficient permissions like publish_stream, offline_access for it and I am using it's Graph API with PHP but it post to only those who are either the developer of the app or the administrator of the app. I dont know where i am doing the mistake. However one of my friend has successfully done it through objective c(iphone) code. I checked his code he was doing the same way as I am doing. Please help me over it. Here is my code and I am using facebook sdk 3.0 -:
if(isset($_POST['submit'])) {
$sendTo = $_POST['friend'];
$link = $_POST['link'];
$message = $_POST['message'];
$attachment = array('message' => $message, 'link' => $link );
if($result = $facebook->api("/$sendTo/feed/",'post', $attachment))
{
$feedbackMessage = "Message sent to friend $sendTo";
}
else
{
$feedbackMessage = "Oops something went wrong";
}
}
First of all, I would suggest that you will take a look at the recent update to facebook developers roadmap:
https://developers.facebook.com/roadmap/
February 2013 Breaking Change:
"Removing ability to post to friends walls via Graph API
We will remove the ability to post to a user's friends' walls via the Graph API. Specifically, posts against [user_id]/feed where [user_id] is different from the session user, or stream.publish calls where the target_id user is different from the session user, will fail. If you want to allow people to post to their friends' timelines, invoke the feed dialog. Stories that include friends via user mentions tagging or action tagging will show up on the friend’s timeline (assuming the friend approves the tag). For more info, see this blog post."
As mentioned by CBroe, the fact that only app administrators/developers can post might be related to the sandbox settings.
Anyway, the api should return a detailed error.
I want to find out the latest comments and likes on a facebook page given a timestamp. Is there a way we can fetch this data from the facebook API? For example : If a user A posted something on my page 30 days back, and user B liked the post and commented on it today. I need to get these activities in the response if I try and find out all activities on my page in the past 2 days (even if the post is 30 days old).
That is not working via the API, the since parameter only works on posts. A possibility is:
comments_after_that_time = 1349285260;
$comments = json_decode(file_get_contents("https://graph.facebook.com/[yourpost_id]/comments?access_token=xxx"));
foreach($comments->data as $comment)
{
if(strtotime($comment->created_time) > comments_after_that_time)
{
echo "we have a new comment";
}
}
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.
My requirement was to update members status from my site, i am also thinking about displaying their friends photos and their last status update.
I have looked all over the docs and cant decide which works for my need. RESTful API, JavaScript API, FQL, XFBML, FBML, FBJS ?? whcin one works best? or best way?
It should be like, when they first go to the page,there will be nothing but a login option. when they click on it, a pop up should appear and when they are authorized, we display a text area to post update. Here, i wanted to show their friends pics too
when they came back later, they should able to post right away, must not ask for login again.
Can some one help me with the code?? I dont expect you to write everything, get the friends pic and their last update into a PHP array would be nice.
Many thanks
If u need to update users data stored at ur database so u will use the facebook API to check user signed in and get his data. i have an ifram application at facebook and i am using C# code (asp.net application) and when the user request the application i authenticate that he is signed in to facebook and check if he is already exist in my database? if not so i get his information(by using facebook API) and add the user in my data base and each time he visits the application i update his information.
With respect to his friends i get all facebook ids of the user friends and then loop these IDs and get the pic of each ID.
Download Facebook Developer Toolkit that enables u communicate with facebook and use facebook API to get user information.
hope that is will help u
Visit my application in facebook and u will see these features at the following link :

Getting the session Key :
protected void Page_Load(object sender, EventArgs e)
{
//Facebook code for integration with facebook users:
_fbService.ApplicationKey = "Application Key";
_fbService.Secret = "Secret Key";
_fbService.IsDesktopApplication = false;
string sessionKey = (string)Session["Facebook_session_key"];
if (Session["Facebook_userId"] != null)
userId = (long)Session["Facebook_userId"];
// When the user uses the Facebook login page, the redirect back here will will have the auth_token in the query params
string authToken = Request.QueryString["auth_token"];
if (!String.IsNullOrEmpty(sessionKey))
{
_fbService.SessionKey = sessionKey;
_fbService.uid = userId;
}
else if (!String.IsNullOrEmpty(authToken))
{
_fbService.CreateSession(authToken);
Session["Facebook_session_key"] = _fbService.SessionKey;
Session["Facebook_userId"] = _fbService.uid;
Session["Facebook_session_expires"] = _fbService.SessionExpires;
}
else
{
Response.Redirect(#"http://www.Facebook.com/login.php?api_key=" + _fbService.ApplicationKey + #"&v=1.0");
}
userId = _fbService.uid;
//End of Facebook code
}
