Laravel - Add a Default Value to Form Submission

this may seem like an odd question, but in my controller I've got the destination columns and the origin fields for specific data entered in my create function. However, I've got a few default values in here, like below:

    $shipment->shipment_billing_status = 1;
    $shipment->created_by = $user_id;
    $shipment->cn_billtoName = request('cn_billtoName');

As you can see $shipment->shipment_billing_status default value should always be 1. However, in extreme cases, I would like a user to be able to choose (if they need to) between two checkboxes, titled "No Settle" and "No Charge", or their values being 2 and 3.

So in those extreme cases, I want a record to absolutely go to 1 if the "No Settle" or "No Charge" checkboxes aren't selected.

Thanks - Matt
