A beginner in this area, I have been able to read a record from a
MySQL database and populate an HTML form (wow!). Now, my goal is to

prevented?

I use a function, myrandomPIN (), to generate random PIN numbers.
The following sql query updates records with the SAME PIN number but.
I want to generate DIFFERENT pin numbers for every record. The
function is ok but I can't figure out how to run it individually for
each record. In other words I do not know the correct syntax to use
UPDATE in a loop (if necessary) so that a different call to the
function is done every time or ecah...

Setup: I only have one database with one table in it. The first page has a form that adds a record (w/ 6 fields in it) to the mySQL database's lone table via PHP. This works fine.

I have my table set up so that there is a 7th field, called "rid" to act as a "record id" or unique identifying field. This is primary and auto-incremented. There...
