nuBuilder Forum

Is it possible to check previous (old) field value in BS and BD event handlers to make some rows in DB table unchangeable?

For now I think about retrieving values from DB and comparing, but maybe on client side (JS) or server (PHP) but without DB query.

When the Before Save and Before Delete event handlers are triggered, nuBuilder does not store the previous field values in memory/in the session. Therefore, to check the previous value of a field, you must retrieve it from the database using a query.

Thanks. Also I think about some hidden boolean field with "True' values means "PROTECTED" and set it by phpMyAdmin

Is this possible with phpMyAdmin?
