Pass custom field data to custom shipping code

How to pass a custom checkout field's value into your custom shipping code using a data attribute.

If your custom shipping code needs to react to something a customer enters on the checkout — like a delivery preference or a special instruction — you can pass a custom field’s value into the shipping rate request.

Steps

  1. 1

    Add a data-fc-shipping-custom-field data attribute to your custom field’s form element.

  2. 2

    When the customer changes that field, Foxy automatically refreshes the shipping rates and includes the field’s value in the payload sent to your custom shipping code, inside the fx:custom_fields object.

Notes

  • Any custom session attributes already in the customer’s session are included in the payload the same way, by default.

  • For the full details on writing custom shipping code itself, see the shipping documentation for the Custom Shipping Code option.
