Check if user has liked a post or not GRAPH API FACEBOOK[with files].HELP
PLEASE

I want to design a news feed with fully functioning likes/Unlike ,share
and commenting,and of course fetching recent posts from users newfeed.Now
here is the thing,I want to check whether a user has liked a post (type is
video, photo, link or status).
If a user has liked the post already, then show unlike button, if a user
has not liked, show like button.
FILES:
index.php click to open the file
Now there are few problems here: 1- problem is that when ever i run this
code,it shows only one post from newsfeed.but if i remove the following
code from the code,it will fetch 20 posts from newsfeed .i dont know whats
happening.
$ret = $facebook->api(array(
'method' => 'fql.query',
'query' => "SELECT like_info FROM $type WHERE object_id=$object_id"
));
$checklike = $ret['data']['like_info']['user_likes'];
2-we can use object_id only for photos,albums,and videos.but you cant use
it to get like_info fro link and status types.so i need new way and a new
technique to findout wether user has liked an post or not
3-whenever i add a new $facebook->api() inside the foreach loop,it will
fetch 1-3 posts from fb or even not all.
so if you could find anyway to make a news feed with fully functioning
likes/Unlike ,share and commenting,and of course fetching recent posts
from users newfeed OR fixing the problems i mentioned ,That would be
greatful.
please help me as soon as possible,if you need anything ,just comment and
i will provide you with.
Thanks.
