Send email when entity field value is changed

Question

I have used Rules module for notification when node is created, edited or deleted.

My site is in three languages and I use Entity Translation for translating node's field.

Now I want notification when node's or entity field is changed/updated. Can I achieve it with Rules module?

Answer 1

Yes, you can use Rules to achieve this.

Here's how:

1. Create new rule that will react on "After updating existing content" event.
2. Use the following conditions: data comparison: node:field-your-field and node-unchanged:field-your-field and select "Negate: FALSE"
3. Create whichever actions you want, e.g. send mail, show message, etc.
