Question

Right now, when I submit a form, I get this in my URL:

http://www.taiwantalk.org/users/admin/edit/?updated=true

It’s a form to updates an user’s profile (I’m using WordPress
but I guess that ?updated=true is a php thing).

I want to build a if-statement with that information:

if ( form=updated] ) {
//do this
}

How to build an if-statement based on the submitted or updated status of the form?

EDIT:

The source code of the form (just in case):
