如何通过 Facebook API 发布多张照片

Question

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:

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For each photo in the story, upload it unpublished using the {user-id}/photos endpoint with the argument published=false .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

Answer 2

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-

Answer 3

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.

PS 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'];

Answer 4

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.

Answer 5

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
