Instance Method Details

#checkout_form_attribute_hidden_fields(checkout_form) ⇒ String

Renders hidden input fields preserving every attribute of a checkout form,
so multi-step checkout flows can carry previously submitted values forward.

Array-valued attributes emit one hidden field per element using the
checkout_form[attr][] naming convention; scalar values emit a single
hidden field. Blank values are skipped.

Parameters:

  • checkout_form (Object) —

    the checkout form object whose attributes are re-rendered

Returns:

  • (String) —

    HTML-safe hidden input tags for all present attributes
