Default checkboxes to export records

Okay not sure if im putting this in the correct form.

My question is, I have been developing an online telephone directory. When you type in your search criteria you are displayed your results in rows,if the count goes over 15 there is a next link to go to the next 15 results etc, you get the idea. To remember the post criteria I have used sessions.

Anyway my problem is that I want to put little check boxes at the start of each record so users can click them and then export them, when they are finished I want to be able to display all the checked items. Im not sure how to do this, I was thinking of perhaps putting all the checked resord id's into a array and storing it in a session, but Im not sure if its possible. Anyone any ideas of how to do it or seen some tutorials around? I dont want anyone to write code for me just point me in a direction to start or some tips? I dont really want my users to have to click a submit buttton every time they select a couple records on a page.

Thanks in advance

Trick your users -- have all your page links (next, prev, "go to page..") submit the form instead of perform a simple redirect. All checked items should be stored into a session. That way, when a user goes BACK to a page that has previously checked items, they can choose to UNcheck them as well.

The only problem here is that you have to be a little clever to figure out if a user has unchecked an item. You need to know all of the items that were displayed on that page, which of those items are already checked in the session, and which items are checked in the submitted form.

It shouldn't be terribly difficult. If you want next/prev to be hyperlinks, you'll need to generate the javascript which submits the form. Or, you can have the next/prev be submit buttons (or images), whatever.

Make sense?


Take care,

Nik
