@NogDogSep 13.2005 — #I think I'd use a sub-array within the $_SESSION array, and just unset all of its elements and then repopulate it for each set checkbox. E.g., if the inputs were sent with an array name such as this...

PHP, Checkboxes and Sessions
Ok, I’ve run into a slight problem
I’ve got a long list of objects, so much that I must paginate them for any kind of easy reading.
But now, I’m trying to add a compare functionality that will let me select a number of objects. When the ‘compare’ button is clicked, it will list the objects next to each other on a new page.
I do this by adding any checked objects to a session variable after the page is submitted. If the next or previous button is pressed, it submits the form to the page with the next 20 or so objects.
I can add the items fine, but my problem comes in when I want to go back and remove an object from the session variable after it’s already there.
This is because, if you deselect a checkbox and resubmit the form, it is no longer in the $_POST array.
Does anyone have any ideas on how to remove a deselected object from the session array?
If you need more info, I’ll be happy to provide it.
