mmx38 on "Call a function when post is updated!"

Hello!

I created a post (of custom type) and I want to update some of the details (eg the title). On the update I want to run a custom function to update a table outside wordpress. I do not know how to distinguish that the post is updated so I can run the function.

I know how to run a function when the post is created but not when it is updated..

Any suggestions?

Thanks in advance!
