Checkbox Next To Each Product In Product_listing.php

[Code Red]

I want to be able to add a checkbox next to each product in the product_listing module. This in itself is straightforward enough, but I want to be able to make selections across several results pages. Now if this was a standard form with a "submit" button there would be no problem with that, but the product listings are navigated using the $listing_split links at the bottom of the page, each with a different action. How do I incorporate a form submit command into these links (or otherwise GET or POST the products selected on that page onto the next page) but that still allows them to move back/forward through the listing pages as normal?

 

I've had a look at the Compare Products contribution on the site, but I don't like the way it's handled - each click of a checkbox causes a form to be processed and the page to reload, which is pretty laborious if you want to make lots of selections on a page.

 

Any ideas?

Just had a thought - could I use sessions to store this data? I've never done anything with sessions before and don't even understand how they work so I'm stabbing in the dark here.
