I wan't to create a new wall post on a appliaction page or a "normal" page with the facebook graph API. Is there a way to "post as page"? With the old REST-API it worked like this:
$facebook->api_client->stream_publish($message, NULL, $links, $targetPageId, $asPageId);
So, if I passed equal IDs for $targetPageId and $asPageId I was able to post a "real" wall post not caused by my own facebook account.
Thanks!
$result = $facebook->api("/me/accounts");
foreach($result["data"] as $page) {
if($page["id"] == $page_id) {
$page_access_token = $page["access_token"];
break;
}
}
$args = array(
'access_token' => $page_access_token,
'message' => "I'm posting as a Page!"
);
$post_id = $facebook->api("/$page_id/feed","post",$args);
To publish as Page you need to add manage_pages permission first of all (and get the tokens).
Next use something like this:
$url = 'https://api.facebook.com/method/stream.publish?message=TEST&target_id=PAGEID&uid=PAGEID&access_token=YOUR_TOKEN';
$ch = curl_init();
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, "");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
Set the value of targetpageid=null and check the output...

I am developing a blog module. When the admin add a new blog post, a new post will be made in the facebook wall of a page(Let's call it Mypage). The code for it is:
$_accessKey = FB_ACCESS_KEY;
$_feedId = FB_FEED_ID;
$attachment = array(
'access_token' => $_accessKey,
'message' => $postData['message'],
'name' => $postData['name'],
'description' => $postData['caption']
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://graph.facebook.com/'.$_feedId.'/feed');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close ($ch);
In the above code:
FB_ACCESS_KEY is the access token of the App from an user Test
FB_FEED_ID is the feed id of the page.
Now the posting to the Mypage is working, but the posts are coming as Added by Test.
How can I make the post as if it was made by the Mypage itself?
Test is an administrator of the page Mypage.
Authenticating as a Page should solve the issue for you: https://developers.facebook.com/docs/authentication/pages/
From one tutorials here:
Post a reply on a comment in Facebook using cURL PHP / Graph API
I tried to post comment to after one post, But return:
[type] => OAuthException [message] => (#200) The user hasn't authorized the application to perform this action
This is not my app acount wall's post id, I tried to my freinds wall, he have allowed my app, I can post a post to his wall, but failed in a comment, I got the post id via
https://graph.facebook.com/<his fid>/feed?access_token=140XXXXXXXXXXX, so the post id has no problem.
What steps have I missed?
$fbId = '100001102789652_233997699980321';
$accessToken = '140XXXXXXXXXXXX';
$url = "https://graph.facebook.com/{$fbId}/comments";
$attachment = array(
'access_token' => $accessToken,
'message' => "Hi comment",
);
// set the target url
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$comment = curl_exec($ch);
curl_close ($ch);
$comment = json_decode($comment, TRUE);
print_r($comment);
?>
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
should be
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($attachment));
as you can't post an array
I wanted to ask if/how is it possible to tag a photo using the FB API (Graph or REST).
I've managed to create an album and also to upload a photo in it, but I stuck on tagging.
I've got the permissions and the correct session key.
My code until now:
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
$token = $session['access_token'];//here I get the token from the $session array
$album_id = $album[0];
//upload photo
$file= 'images/hand.jpg';
$args = array(
'message' => 'Photo from application',
);
$args[basename($file)] = '#' . realpath($file);
$ch = curl_init();
$url = 'https://graph.facebook.com/'.$album_id.'/photos?access_token='.$token;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$data = curl_exec($ch);
//returns the id of the photo you just uploaded
print_r(json_decode($data,true));
$search = array('{"id":', "}");
$delete = array("", "");
// picture id call with $picture
$picture = str_replace($search, $delete, $data);
//here should be the photos.addTag, but i don't know how to solve this
//above code works, below i don't know what is the error / what's missing
$json = 'https://api.facebook.com/method/photos.addTag?pid='.urlencode($picture).'&tag_text=Test&x=50&y=50&access_token='.urlencode($token);
$ch = curl_init();
$url = $json;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_exec($ch);
} catch(FacebookApiException $e){
echo "Error:" . print_r($e, true);
}
I really searched a long time, if you know something that might help me, please post it here :)
Thanks for all your help,

Hey,
you can tag the Picture directly on the Upload with the GRAPH API,
see the example below:
This Method creates an array for the tag information, in this examples the method becomes an array with Facebook user Ids:
private function makeTagArray($userId) {
foreach($userId as $id) {
$tags[] = array('tag_uid'=>$id, 'x'=>$x,'y'=>$y);
$x+=10;
$y+=10;
}
$tags = json_encode($tags);
return $tags;
}
Here are the arguments for the call of the GRAPH API to upload an picture:
$arguments = array(
'message' => 'The Comment on this Picture',
'tags'=>$this->makeTagArray($this->getRandomFriends($userId)),
'source' => '#' .realpath( BASEPATH . '/tmp/'.$imageName),
);
And here is the Method for the GRAPH API call:
public function uploadPhoto($albId,$arguments) {
//https://graph.facebook.com/me/photos
try {
$fbUpload = $this->facebook->api('/'.$albId.'/photos?access_token='.$this->facebook->getAccessToken(),'post', $arguments);
return $fbUpload;
}catch(FacebookApiException $e) {
$e;
// var_dump($e);
return false;
}
}
The argument $albId contains an ID from an Facebook Album.
And if you want to Tag an existing Picture from an Album you can user this Method:
At First we need the correct picture ID from the REST API, In this example we need the Name from an Album wich the Application has create or the user wich uses this Application.
The Method returns The Picture ID From the last Uploaded Picture of this Album:
public function getRestPhotoId($userId,$albumName) {
try {
$arguments = array('method'=>'photos.getAlbums',
'uid'=>$userId
);
$fbLikes = $this->facebook->api($arguments);
foreach($fbLikes as $album) {
if($album['name'] == $albumName) {
$myAlbId = $album['aid'];
}
}
if(!isset($myAlbId))
return FALSE;
$arguments = array('method'=>'photos.get',
'aid'=>$myAlbId
);
$fbLikes = $this->facebook->api($arguments);
$anz = count($fbLikes);
var_dump($anz,$fbLikes[$anz-1]['pid']);
if(isset($fbLikes[$anz-1]['pid']))
return $fbLikes[$anz-1]['pid'];
else
return FALSE;
//var_dump($fbLikes[$anz-1]['pid']);
//return $fbLikes;
}catch(FacebookApiException $e) {
$e;
// var_dump($e);
return false;
}
}
Now you have the correct picture ID From the REST API and you can make your REST API CALL to tag this Picture $pid is the Picture from the Method getRestPhotoId and $tag_uid is an Facebook userId:
$json = 'https://api.facebook.com/method/photos.addTag?pid='.$pid.'&tag_uid='.$userId.'&x=50&y=50&access_token='.$this->facebook->getAccessToken();
$ch = curl_init();
$url = $json;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_GET, true);
$data = curl_exec($ch);
And this line is very important:
curl_setopt($ch, CURLOPT_GET, true);
you must youse CUROPT_GET instead of CUROPT_POST to add a Tag throw the REST API.
I Hope this helps you.

Photo id is unique for every user and looks like two numbers joined by underscore in the middle.
Getting this id is a bit tricky.
You can get it by running FQL on photo table but you need to provide album id which is also user unique. You can get album id from album table but you need to provide owner userid.
For example we have CocaCola user with userid 40796308305. To get photo ids from this user we can run FQL:
SELECT pid FROM photo WHERE aid IN ( SELECT aid FROM album WHERE owner="40796308305")
(you can run it in a test console on this page)
This would return our photo ids:
[
{
"pid": "40796308305_2298049"
},
{
"pid": "40796308305_1504673"
},
{
"pid": "40796308305_2011591"
},
...
]
I didn't work with photos much, maybe you don't have to go through all this process to get photo id, it might be some simple algorithm like <OWNER_ID>_<PHOTO_ID>. But try to get your photo id from FQL and see if tagging would work. If it does maybe you will be able to skip FQL part and build photo id from existing data you have.
Hopefully this helps.
I found out the problem, the problem is that when you use curl to send the array the post function will not send the array correctly, it was sending just "Array" that it was why the graph API complained about tags being an array. To solve that I did the following:
$data = array(array('tag_uid' => $taguser,
'x' => rand() % 100,
'y' => rand() % 100
));
$data = json_encode($data);
$photo_details = array(
'message'=> $fnames,
'tags' => $data
);
Now I just send using curl
curl_setopt($ch, CURLOPT_POSTFIELDS, $photo_details);
I have an application that uses the old Facebook API but now I'm migrating it. The application works good until I try to upload a photo.
I knew how to do it in the old way, but now... I'm in troubles.
This is the way I used to do it:
$args = array
(
'method' => 'photos.upload',
'v' => $ver,
'api_key' => $key,
'uid' => $uid,
'call_id' => $cid,
'format' => 'XML',
'caption' => $caption
);
signRequest($args, $sec);
$args[basename($file)] = '#' . realpath($file);
$ch = curl_init();
$url = 'http://api.facebook.com/restserver.php?method=photos.upload';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$data = curl_exec($ch);
Any ideas??
Thanks
The API url starts with https:// not http://. That could be the issue.
I found the solution here:
Uploading a picture to facebook
There is shown how to use the new Facebook Graph API with the PHP Curl function and a valid session token.
I've been struggling to upload an image from the user's computer and posted to our group page using the Facebook Graph API. I was able to send a post request to facebook with the image however, I'm getting this error back: ERROR: (#200) User must have accepted TOS. To some extent, I don't believe that I need the user to authorize himself as the photo is being uploaded to our group page. This below, is the code i'm using:
if($albumId != null) {
$args = array(
'message' => $description
);
$args[basename($photoPath)] = '#' . realpath($photoPath);
$ch = curl_init();
$url = 'https://graph.facebook.com/'.$albumId.'/photos?'.$token;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$data = curl_exec($ch);
$photoId = json_decode($data, true);
if(isset($photoId['error'])) die('ERROR: '.$photoId['error']['message']);
$temp = explode('.', sprintf('%f', $photoId['id']));
$photoId = $temp[0];
return $photoId;
}
Can somebody tell me if I need to request extra permissions from the user or what i'm doing wrong?
Thanks very much!
Actually, I never succeeded in this :(. As a work around, we created a new facebook user instead of a group page.
This is a known bug and it looks like they're working on it:
