For anybody else that wants this functionality, here is what I did.
Set the user_id as a transient in the database after the user object is created.
add_action( 'rwmb_profile_after_save_user', 'set_user_id_as_transient', 10 ,1 );
function set_user_id_as_transient( $object ) {
set_transient( 'user_id', $object->user_id, HOUR_IN_SECONDS );
}
Then modify the form submission with the transient data.
add_filter( 'rwmb_frontend_insert_post_data', 'insert_user_id', 10, 2 );
function insert_user_id( $data, $config ) {
$user_id = get_transient( 'user_id' );
if ( false !== $user_id ) {
$data['post_author'] = $user_id;
}
return $data;
}
Ahn, please mark as complete.
