Is there a hook for a field?

Hi
I’m searching a hook for a field (type structured field) but I did not find anything.

When the field updates I want to save the update-date to another field.
Is this possible?

Kind regards
Alain

There is no such thing as a field hook, only a page.update:after hook which relates to the whole page being updated. However, inside this hook you can check if a particular field has changed by comparing the before/after values and act on that.

Thanks Sonja for this idea :slight_smile:

Check this if some stumbles over the same point:
