By using this code:
$url2 = "https://graph.facebook.com/{$group_id}/feed?limit=500&access_token=XXXXXXXXXXXXX";
$data = json_decode(file_get_contents($url2));
I get json like this:
stdClass Object
(
[message] => bla bla bla bla bla bla
[updated_time] => 2016-12-23T08:31:25+0000
[id] => 000000000000_111111111111
)
The first part (0000...0) is the group id. The second part (1111..1) is the post id. I need the details of the post owner (id, name, profile picture).
You can help me please? Thanks.
The API reference tells you which fields you can get for a post: https://developers.facebook.com/docs/graph-api/reference/v2.8/post
For example, to get the name of the creator:
/{group-id}/feed?limit=500&fields=id,from
...or if you want to get profile pictures too:
/{group-id}/feed?limit=500&fields=id,from{id,name,picture}
It is called "Declarative Fields" and came with v2.4 of the Graph API. You need to specify the fields you want to get in the result.
