How do I can post a multiple photos via Facebook API

Question

Now I posting a single photo to wall like this:

$response = $facebook->api(\"/$group_id/photos\", \"POST\", array(
    \'access_token=\' => $access_to         


        

Answer 1

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For each photo in the story, upload it unpublished using the {user-id}/photos endpoint with the argument published=false.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"}'
  )
);
