How to tag photos in facebook-api?
- by Camillo
Hey,
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,
Camillo
