Change ID to Slug in remote submission

Hi,
I’m trying to submit a form to a remote URL. It works perfectly with ID/Value pairs while I’d like to have Slug/Value pairs.
I’m using this to replace it but somehow it seems to skip all the dropdowns.

foreach( $data as $field_id => $field_value ){
        $data[ $form[ 'fields' ][ $field_id ][ 'slug' ] ] = $field_value;
    }

My php-skills are limited. Can anybody see what’s wrong here?
