My problem seems relatively simple, if fieldB == “”, then fieldB == fieldA.

Correct me if im wrong but in my case I would use beforesave(). When I click save I want to check if the textbox value for fieldB is empty. If so, set the textbox value of fieldA to the fieldB field. How do I reference the textbox value of those fields?

Yes. the beforeSave() hook sounds like the right place for this:

Code: Select all

function beforeSave($record){    if ( !$record->val('fieldA') ){       $record->setValue('fieldA', $record->val('fieldB'));    } }

I dont know why but I was assuming record->val(‘fieldA’) looked at the value within the database not the textbox itself.

The $record parameter passed to beforeSave is a Dataface_Record object. Its values at that time include any unsaved changes (i.e. any data entered from an edit form).
