* This implementation of get_objects_by_id() is a bit hacky since we're not passing in an array of meta IDs, |
| 11 |
* but instead an array of post or comment IDs for which to retrieve meta for. On top of that, |
| 12 |
* we also pass in an associative array where we expect there to be 'meta_key' and 'ids' keys present. |
| 13 |
* |
| 14 |
* This seemed to be required since if we have missing meta on WP.com and need to fetch it, we don't know what |
| 15 |
* the meta key is, but we do know that we have missing meta for a given post or comment. |
| 16 |
* |
| 17 |
* @param string $object_type The type of object for which we retrieve meta. Either 'post' or 'comment' |
| 18 |
* @param array $config Must include 'meta_key' and 'ids' keys |
| 19 |
* |
| 20 |
* @return array |
