Storing selected values in chained select boxes with PHP's $_GET autoglobal?

[pufftissue]

Hi,

I have chained select boxes with PHP, and I'd like to store the selection values in each one.

So,

select box 1 (save selected value) then submit, and leads to PHP-generated select box 2:
select box 2 (save selected value) then submit, and leads to PHP-generated select box 3:
select box 3 (save selected value) then submit, and leads to :

display all selections so far.

I've been using a $GET autoglobal array, and for some reason only one $GET value is ever stored, not 3 of them.

sounds like you want SESSIONS, but some actully code would help

Also note that it sounds like you have a perfect chance to use AJAX to minimize bandwidth/waiting time. When the user selects an option in the first box, use AJAX to query a PHP script and get the values for the next box (which can be auto-populated using Javascript).
