Add checkbox to Ubercart checkout It sounds quite easy, adding a checkbox to Ubercart's checkout form. The consultant I spoke to told be to use hooks, or try using the uc_extra_fields_pane module, which I also cannot get to work properly (it's config page is not showing up). I'm using Ubercart 2 and Drupal 7.22.
In your custom module use the hooks defined in the Ubercart terms and conditions module.
