save multi-page checkbox array to session

[andrewdunstall]

Hi,
I have some pages being paginated by PHP. The pages contain form checkboxes. On the final page there is a "submit" button.
I need each pages selected checkboxes displayed when submit button is pressed.

How do I collect all the checkboxes values from each page?

I was thinking of trying javascript "OnUnload" handler to file off some code which would copy the values in each pages checkbox array to a session. When the next pages appears, and the viewer selects more checkboxes, these new values would then be added to the existing array held in the session variable.

Does an onUnload handler seem like a reasonable idea? I assume I would I need to 'array_push' the new values into the session array? Am I overlooking something?
Can anyone give me some help?

Thx, Andy.

ok not sure exactly what you want to do but

note: tonnnes of typos, but its the idea im trying to get accross, assuming this is what your looking for

<?php

// first page
// im still suing a shit old version of php 4 and i use $http_user_vars or something,
// so its //up to you to put in your $_post stuff for later versions 
// if you want to use coding //conforming formats
// this is how you grab your chcks boxes into an array

$checks_box_array = $checks;

if (is_array($checks))
foreach ($checks as $key => $value ){
$my_big_long_string .= $my_big_long_string .,"$key = $value"; 
// your checkboxes and values are stored in one big long string which you will explode() later

// code to add this to your session
// you might also grab and big_long_strings which are already in your session and
// add them to your $my_big_long_string, messy but it will owrk, you could alwasy
// use a db, to store it temporarly using the sessionid as the table name and 
// destroy the table later
}
