tagging a page in photos - php

Greetings
Here's what's up:
I'm working on an app where the user or a page they administrate is tagged in their own image, however, tagging a page they administrate doesn't function, I have no trouble with the user being tagged.
Here's some code:
$tdata = array('tag_uid' => $fb_id,'x' => 0,'y' => 0);
$datatags[] = $tdata;
$attachment = array(
'access_token' => $access_token,
'tags' => $datatags
);
$attachment['image'] = '#'.realpath($image_name.);
$result = $facebook->api('/'.$album_id.'/photos', 'POST', $attachment);
$fb_id is either the ID for the user or the page. which is grabbed using /me/accounts in the Graph API
Thanks!

Per the documentation you cannot do this:
You can specify which user to tag using two methods: in the URL path
as PHOTO_ID/tags/USER_ID, or in a URL parameter as
PHOTO_ID/tags?to=USER_ID. Currently, you cannot tag a Page in a photo
using this API.

How to tag user(s) in comment via facebook php sdk?

I'm trying to tag user(s) inside page post comments.
$fb_id = 'facebook_user_id_here';
$fb_name = 'facebook_user_name_and_surname_here';
$request = new FacebookRequest(
$this->session,
'POST',
$comment,
array(
'access_token' => $this->page_access_token, //it is access token of my page
'message => "Text here #[".$fb_id.":1:".$fb_name."]"
)
);
It shows only name and surname without Fb profile URL.
Like CBroe mentions in his comment, at this time this is not possible using the API.
For reference, this is called "mentioning" or "mention tagging", and personal profiles can only do this in messages on open graph actions (docs).
Pages can also mention other pages in comments. (docs)

How do I can post a multiple photos via Facebook API

Now I posting a single photo to wall like this:
$response = $facebook->api("/$group_id/photos", "POST", array(
'access_token=' => $access_token,
'message' => 'This is a test message',
'url' => 'http://d24w6bsrhbeh9d.cloudfront.net/photo/agydwb6_460s.jpg',
)
);
It works fine, but can I somehow post a multiple photos, something like this:
You can now publish multiple images in a single post to your feed or page:
For each photo in the story, upload it unpublished using the {user-id}/photos endpoint with the argument published=false.
You'll get an ID for each photo you upload like this:
{
"id": "10153677042736789"
}
Publish a multi-photo story using the {user-id}/feed endpoint and using the ids returned by uploading a photo
$response = $facebook->api("/me/feed", 'POST',
array(
'access_token=' => $access_token,
'message' => 'Testing multi-photo post!',
'attached_media[0]' => '{"media_fbid":"1002088839996"}',
'attached_media[1]' => '{"media_fbid":"1002088840149"}'
)
);
Source: Publishing a multi-photo story
You can make batch requests as mentioned here: https://stackoverflow.com/a/11025457/1343690
But its simple to loop through your images and publish them directly.
foreach($photos as $photo)
{
//publish photo
}
Edit: (regarding grouping of photos on wall)
This grouping is done by facebook automatically if some photos are uploaded into the same album.
Currently you cannot create an album in a group via Graph API - it is not supported (as of now), see this bug.
But you can do this - create an album manually, then get the album_id by-
\GET /{group-id}/albums, then use the the code with album_id instead of group_id-
foreach($photos as $photo){
$facebook->api("/{album-id}/photos", "POST", array(
'access_token=' => $access_token,
'name' => 'This is a test message',
'url' => $photo
)
);
}
I've tested it, see the result-
Actually you can upload a multi story photo(I did it using Graph Api and PHP) but the problem comes if you need scheduled this post.Your post is schedule but also it shows on the page's feed.
P.S. I'm using Graph Api v2.9
PHP Code
$endpoint = "/".$page_id."/photos";
foreach ($multiple_photos as $file_url):
array_push($photos, $fb->request('POST',$endpoint,['url' =>$file_url,'published' => FALSE,]));
endforeach;
$uploaded_photos = $fb->sendBatchRequest($photos, $page_access_token);
foreach ($uploaded_photos as $photo):
array_push($data_post['attached_media'], '{"media_fbid":"'.$photo->getDecodedBody()['id'].'"}');
endforeach;
$data_post['message'] = $linkData['caption'];
$data_post['published'] = FALSE;
$data_post['scheduled_publish_time'] = $scheduled_publish_time;
$response = $fb->sendRequest('POST', "/".$page_id."/feed", $data_post, $page_access_token);
$post_id = $cresponse->getGraphNode()['id'];
You will need to upload each photo first with published state to false, and then use the ID's of the unpublished photos to the /me/feed endpoint to schedule the photo. The schedule needs to be within the 24 hours from the time the photos are uploaded as facebook deletes all unpublished photos in 24 hours.
Ref:
https://developers.facebook.com/docs/graph-api/photo-uploads/
There is no way to publish more than one photo in the same graph API call.
See documentation: https://developers.facebook.com/docs/graph-api/reference/user/photos

Is it even possible to tag photos in Facebook?

I'm reading wildly different things about tagging photos on Facebook.
One article says you can send tags=array(...tag_uid...) at the same time as you post the photo: Tagging photos on Facebook with Graph API / PHP SDK
One article said you can tag, but first you have to post to photo, and then set tags afterwards. (Can't remember the page)
One article said you can tag, but only one tag per request, so you have to iterate over the array. (Can't remember the page)
One article says you can't tag at all: https://developers.facebook.com/blog/post/371/
Does anyone know if tagging actually possible, and what is the correct way of doing it as of the current date?
You must get Photo ID firs and then tag someone on this photo
upload photo to album
$photo_details = array(
'message' => $message,
'access_token' => $token
);
$photo_details['image'] = '#' . realpath($file);
$uploaded_photo = $facebook->api('/'.$album_uid.'/photos', 'post', $photo_details);
Get Photo ID
$photo_id = $uploaded_photo['id'];
set Friend ID you want to tag
$tags = array(
array('tag_uid' => $friend_id, 'x' => rand() % 100, 'y' => rand() % 100 )
);
tag friend
$facebook->api('/'.$photo_id.'/tags', 'post', array('tags'=>$tags));
It works for me, I hope this will help you

Cannot post entry to facebook fan page wall as an admin

I am trying in vain to post to a Facebook fan page wall as admin. I want to post new entries with pictures, link, description etc on my fan page wall. This is integrated into my custom cms so that whenever a story is updated on my website, it automatically posts the same on the fan page wall.
The problem is that whenever I post, the post does not appear as posted by admin. It appears as posts by others on the right side of the timeline.
How do I go around the following code so that it posts as admin on my fan page wall? I been looking at it for two days, checked similar stuff on the web and so, but I still cant seem to crack it. Help will be appreciated.
$page_id = 'xxxxxxxxxx';
$article_link = "http://xyz.com/articles/headlines/title-one/";
$result = $facebook->api("/me/accounts");
foreach($result["data"] as $page) {
if($page["id"] == $page_id) {
$page_access_token = $page["access_token"];
break;
}
}
$og_title = "Sample title";
$og_image = "http://xyz.com/images/articles/919161344090182.jpg";
$msg = "some description of the article";
$feed_array = array(
'access_token' => "$page_access_token",
'message' => "$msg",
'picture' => "$og_image",
'link' => "$article_link",
'name' => "$og_title",
'caption' => "$og_title"
);
try {
$page_post = $facebook->api("/$page_id/feed","post",$feed_array);
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
If you want to post as the page - that means that the post will appear as if the page posted an update as it appears here :
Then you will have to use a valid page access token. There is information on how to obtain this kind of token in the Facebook Authentication Documentation. It looks like you already have a token in your code - you can test it using the Facebook Debugger and see if it is still valid.
Another thing you may want to try, instead of appending the token to be one of the parameters of the post array, you could use the setAccessToken() function of the PHP SDK. More details can be found here - https://developers.facebook.com/docs/reference/php/facebook-setAccessToken/
$facebook->setAccessToken($new_access_token);
As a final BTW note, when you specify elements of an array, unless you are wanting to specifically add the quote character, there is no need to wrap the values in quotes.
$feed_array = array(
'access_token' => $page_access_token,
'message' => $msg,
'picture' => $og_image,
...
);
If you want to explicitly add quotes to the values you would have to do something like this -
$feed_array = array(
'string_value' => '"'.$value.'"',
...
);

post photo to friend wall through graph api

I'm trying to post a photo to one of friends wall using the new graph api. For this I have the following code:
$attachment = array(
'message' => 'Posted a photo',
'source' => '#' . realpath(PATH_TO_MY_PHOTO)
);
$facebook->setFileUploadSupport(true);
$facebook->api('/'.$id_friend.'/feed?access_token='.$access_token, 'post', $attachment);
The problem is that the picture is not uploaded. I mean, it only post the message without any picture. This does not work either if I try to post on the current user wall.
Does anyone have any idea on how to achieve this ? Thanks.
p.s. I'm requesting only publish_stream permission
In order to post a poto to a users wall, as in publishing a photo and not a stream story,
you can post to here:
http://graph.facebook.com/ALBUM_ID/photos.
for more information visit facebook's graph api photo documentation.
You should replace "source" with "picture".
$imagepath='http://site.com/pic.jpg';
$attachment = array(
'message' => 'Posted a photo',
'picture' => $imagepath
);
$facebook->setFileUploadSupport(true);
$facebook->api('/'.$id_friend.'/feed?access_token='.$access_token, 'post', $attachment)
You can optionally add some more fields. for more details:
