Hey,

Can you show me the php to use to set a field's value based on another fields value when a new custom post is created/updated?

eg:

date_field = datepicker
number of days field = number
calculated date field = date field + number of days field.

Thanks

Hi,

You can follow this documentation to know how to add a callback function to update a field value to an MB hook
https://docs.metabox.io/actions/rwmb-after-save-field/

and refer to this topic to add a number of days to date https://stackoverflow.com/questions/2332681/add-number-of-days-to-a-date
