Thanks but I really don't have a problem with updating the information. What you wrote is all pretty straight forward for me. The problem im having is knowing how to automatically refresh a page when the user returns to it. I'll clarify the process so you know what i'm trying to do.
Now, here's the bit I am uncertain about. Once the record has been updated, the pop-up window automatically closes, returning the user to the main browser window, which then automatically refreshes displaying the updated information. I guess the real question is how does the pop-up window automatically close, and how does the original browser window know that the user has returned to it and subsequently refresh in order to display the up-to-date info?
I was buying concert tickets online the other day from http://www.princebandroom.com.au and their site worked just like this when I updated my contact details and I thought it would be nice to replicate that for my site.
I hope i've been clear describing this. I'm not even sure if it is PHP that is able to control this but I'd appreciate any ideas you have.
