no data returned when calling $adCreative->read() without specifying fields about facebook-php-business-sdk

[victorarthur]

Hi @paulbain
I have the same issue, I would like to clone the AdCreative (to rename the url_tags and this parameter doesn't available on the /copies node) so I have do download the object and recreate with a different url_tags parameter. In advance, I don't know what fields does the AdObject has so I can not pre-define the fields I would request.

Do you know any solution for this issue?

This is expected behaviour. You should only request the fields from the API that you need as it decreases load and increases performance.

You also cannot read all possible fields of an object. Some fields can only be used when writing.

You can set the default fields to read on an object once which you may want to do if you always read the same fields.

I try to read an AdCreative like this:

Api::init($app_id, $app_secret, $access_token);
$adCreative = new AdCreative($ad_creative_id, $account_id);
$adCreative->read();
print_r($adCreative->getData());
But it results in:

Array
(
[id] => THE ID
[title] =>
[actor_id] =>
[actor_name] =>
[name] =>
[object_id] =>
[object_story_id] =>
[object_story_spec] =>
[body] =>
[image_hash] =>
[image_file] =>
[image_url] =>
[image_crops] =>
[video_id] =>
[actor_image_hash] =>
[link_url] =>
[object_url] =>
[url_tags] =>
[preview_url] =>
[follow_redirect] =>
[object_store_url] =>
[link_deep_link_url] =>
[call_to_action_type] =>
[object_type] =>
)
I then try using $adCreative->getFields() as an argument to $adCreative->read():

Api::init($app_id, $app_secret, $access_token);
$adCreative = new AdCreative($ad_creative_id, $account_id);
$adCreative->read($adCreative->getFields());
print_r($adCreative->getData());
Which throws an exception:

Array
(
[message] => (#100) Tried accessing nonexisting field (image_file) on node type (AdCreative)
[type] => OAuthException
[code] => 100
)
I then remove image_file from the list of fields:

Api::init($app_id, $app_secret, $access_token);
$adCreative = new AdCreative($ad_creative_id, $account_id);
$fields = $adCreative->getFields();
foreach ($fields as $k => $v) {
if ($v = 'image_file') {
unset($fields[$k]);
}
}
$adCreative->read($fields);
print_r($adCreative->getData());
Which results again in no data:

Array
(
[id] => THE ID
[title] =>
[actor_id] =>
[actor_name] =>
[name] =>
[object_id] =>
[object_story_id] =>
[object_story_spec] =>
[body] =>
[image_hash] =>
[image_file] =>
[image_url] =>
[image_crops] =>
[video_id] =>
[actor_image_hash] =>
[link_url] =>
[object_url] =>
[url_tags] =>
[preview_url] =>
[follow_redirect] =>
[object_store_url] =>
[link_deep_link_url] =>
[call_to_action_type] =>
[object_type] =>
)
I try making my own fields array, and then remove any that cause an exception, and end up with this list:

Api::init($app_id, $app_secret, $access_token);
$adCreative = new AdCreative($ad_creative_id, $account_id);
$fields = array(
AdCreativeFields::ID,
AdCreativeFields::TITLE,
AdCreativeFields::ACTOR_ID,
AdCreativeFields::ACTOR_NAME,
AdCreativeFields::NAME,
AdCreativeFields::OBJECT_ID,
AdCreativeFields::OBJECT_STORY_ID,
AdCreativeFields::OBJECT_STORY_SPEC,
AdCreativeFields::BODY,
AdCreativeFields::IMAGE_HASH,
//AdCreativeFields::IMAGE_FILE,
AdCreativeFields::IMAGE_URL,
AdCreativeFields::IMAGE_CROPS,
AdCreativeFields::VIDEO_ID,
AdCreativeFields::ACTOR_IMAGE_HASH,
AdCreativeFields::LINK_URL,
AdCreativeFields::OBJECT_URL,
AdCreativeFields::URL_TAGS,
//AdCreativeFields::PREVIEW_URL,
//AdCreativeFields::FOLLOW_REDIRECT,
AdCreativeFields::OBJECT_STORE_URL,
AdCreativeFields::LINK_DEEP_LINK_URL,
AdCreativeFields::CALL_TO_ACTION_TYPE,
AdCreativeFields::OBJECT_TYPE,
);
$adCreative->read($fields);
print_r($adCreative->getData());
Now I get what is expected (i have replaced the actual data incase of any security issue sharing it):

Array
(
[id] => THE ID
[title] => AD TITLE
[actor_id] => THE ACTOR ID
[actor_name] =>
[name] => AD NAME
[object_id] =>
[object_story_id] =>
[object_story_spec] =>
[body] => AD BODY
[image_hash] => IMAGE HASH
[image_file] =>
[image_url] => https://fbcdn-creative-a.akamaihd.net/REMOVED-PATH.png
[image_crops] =>
[video_id] =>
[actor_image_hash] =>
[link_url] =>
[object_url] => http://www.example.com/
[url_tags] =>
[preview_url] =>
[follow_redirect] =>
[object_store_url] =>
[link_deep_link_url] =>
[call_to_action_type] =>
[object_type] => DOMAIN
)
My question is, is this the expected behaviour? Or should I be able to do $adCreative->read() without specifying a field list?

Ok, makes sense. Thanks for clarifying.

hi cornernote,
where can I get $access_token to put into Api::init($app_id, $app_secret, $access_token); ?
thank you very much

[cornernote]

hey @bibibaonam,

It's explained here:
https://developers.facebook.com/docs/reference/ads-api/overview#access_token

[cornernote]

here is my quick guide:

1. get the AUTHORIZATION_CODE from the URL after going here:
   https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&scope=ads_management&redirect_uri=http://yourdomain.com/

2. get the access token from the URL after going here:
   https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&redirect_uri=https://yourdomain.com/&client_secret=YOUR_CLIENT_SECRET&code=AUTHORIZATION_CODE

[paulbain]

Please don't share access tokens publicly. That's a quick way to get your account into a lot of trouble.
You should consider changing your FB password to invalidate the token you just shared, or uninstalling the app from your FB settings.

[paulbain]

To answer your question, prefix the account ID with act_ like in all the examples:

$account = new AdAccount('act_<YOUR ACCOUNT ID>);
$fields_you_want_to_read = array('name');
$adaccount = $account->read($fields_you_want_to_read);
echo $adaccount->name;

Thank you very much Paulbain.
