function date_views_filter_handler_simple::value_validate in Date 8

Same name and namespace in other branches

2. 7.2 date_views/includes/date_views_filter_handler_simple.inc \date_views_filter_handler_simple::value_validate()

Value validation.

TODO add in more validation.

We are setting an extra option using a value form because it makes more sense to set it there. That's not the normal method, so we have to manually transfer the selected value back to the option.
