function stripe_element_process in Stripe 7

Process callback for this module elements.

TODO: Attach JS through a library defined via hook_library() implementation. TODO: Support form WITHOUT Stripe.js. This would require an configuration variable to be set to TRUE. This will have serious security implications. No UI should be provided to enable this, requiring either a clear and informed user action or usage of third party code.

Parameters

array $element: The processed element.

array $form_state: The form state.

array $complete_form: The complete form.
