Guys
It was a while ago, and I recall two ways of doing it - the blunt and
clumsy way which is not good for internet applications (OK for intranet
where download time isn't an issue) (which I can remember) and the
really cool sophisticated way (which I can't remember off hand, so I'll
have to dig the code out which is going to take me some time - its on a
backup of an old machine).
The clumsy and easy way was to write a small script (php) which took a
variable out of the query string, gave it a useful name and then
returned to the main script at the point of exit (I told you it was
clumsy - you have to set a load of markers in the main script so that
you know where you are up to!). When a javascript variable needed to
passed to php, just call the php script using the jscript variable as
the querystring.
Of course, if you have a whole load to pass at once, you can do it with
a POST method which makes life a bit easier (the way that I initially
did it before I worked out my neat trick which I can't find...) it is
straightforward to call a POST from an update event in jscript (I
triggered it from an update on a drop down list).
I'll dig out the neat way of doing things when I get some time, but it
ain't going to be for a couple of weeks I guess.
