Update disabled text field via hook

If I update a disabled text field via a hook, will it save ?


No, I think there is no way to force update a disabled field atm. And using query language for the disabled property is also not possible, as far as I know.

Is there then any non editable field that can be outputted in a template and that I can update from a hook?

You could use a hidden field. The alternative would be a custom field.
