Code

  /* TODO The 'op' element in the form values is deprecated.
     Each button can have #validate and #submit functions associated with it.
     Thus, there should be one button that submits the form and which invokes
     the normal form_id_validate and form_id_submit handlers. Any additional
     buttons which need to invoke different validate or submit functionality
     should have button-specific functions. */
