This is the sort of technique I use too, where I have to use PHP to get
data I need from a mysql database, but then manipulate it in JavaScript
before using PHP to write it back to mysql.
The values I get from mysql are written into a form with hidden
variables, and their values then picked up with an onload function to be
put into JS variables. The new values are then later loaded into hidden
form variables, and picked up by the next page as PHP values in order to
be written back to the database.
