CodeIgniter: adding a $subresult to an object $result by an ActiveRecord result ID

I think you just need:

$record->threads = $threads;

EDIT:

You just need to assign the reference in your foreach (note the & next to $record):

foreach($records as &$record){    //...    $record->threads = $threads;}return $records;

php codeigniter object activerecord

If the method shown by rojoca doesn't work, you could do this:

$records = $sql->result_array();

Then loop through as usual (except do $record_id = $record['record_id'] instead of $record->record_id), and reference your row like this:

$records[$record_id]['threads'] = $threads;

Though you may not want to rely so heavily on that record_id column always matching perfectly with your iteration index.
