After sleeping on things, it seems that we are all going about things the difficult way to my original problem.
(Yet to be completely confirmed.)
Well, my end goal is that when the user clicks on the Top Check-box, and chooses an action and "Go", that *all* Messages get updated.
We have all been looking at how to pass an entire Array holding all of the Messages back to my script so it knows what to update.
But this morning, I came to this conclusion...
Why not just identify when the user checks the Top Check-box and submits the Form? If that condition is "TRUE" - which is very easy to identify - THEN I can run a SELECT query on my "Inbox", and use that results-set on my UPDATE query.
In other words, instead of running a SELECT query that identifies all of the Messages that need to be updated, and then trying to figure out how to pass that entire list back to the same script, why not take the easier path of just returning a simple Yes/No flag back to the script, [b]and then run the SELECT query?![b]
Just my thoughts...
