Set dynamic value of a field to another field

[tkahn06]

Hey guys!

Ok, so I need to create an field for an "alias id". Basically they have this content managed navigation system where if your on a certain page it shows the link in the navigation column as "active" or highlighted.

The problem arises when the user clicks on the "header" link - something like the Discussions or Forums link at the top of this page.
For some pages the "header" links don't have an actual page assigned to their page_id and some do.

In the case where they do, I need to have a column which stores their actual id and then the one they're linked to.

?id=84 should look the same as ?id=85 where ?id=84 is a "header" link

What I need it a field that takes on, as default, the value of page_id. Is this possible and if so could y'all throw me a bone?

Thanks!


Sorry that I suck at explaining!

Do you mean you want the store the current page_id and the page_id to which it is linked to?

Yeah. Is that doable?

The default page_id alias would be the same row's page_id with the idea that the admin would manually change the page_id alias when the situation called for it.
