Re: maintaining state in multipage form
The only problem with that is that the form isn't linear; in addition to to the "previous page/next page" links, each page has a direct link, so the user can go straight to page 56 if they don't want to have to click "next page" 55 times. But you're right; the bottom line is that each click needs to result in the page's form vars being passed to the next page, which means either 56+ submit buttons or maybe some kind of onClick=form.submit() mechanism. It's a little simpler since I'm dealing only with checkboxes (all have the same name), so I get a comma-delimited list with each submit without having to do a loop, but then the question is how to remove widget IDs from the cumulative list if the user goes back and unchecks them. E.G., user goes to a page and checks the boxes for widgets 42, 44, and 61. Later they go back to that page, uncheck widget 42, and visit another page. Widget 42 has been unchecked, but it still hasn't been removed from the cumulative list, because unchecked checkboxes submit nothing. Hence my idea to create a list or structure that looks like "widgetID|pagenumber, widgetID|pagenumber, widgetID|pagenumber..." with each submission, first remove all elements from the cumulative list that have pagenumber=submitting page's pagenumber, and then append the received widget IDs currently being passed. ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235273 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
Re: maintaining state in multipage form
Have you considered splitting the form accross different tabs and keep it on the same page? Here you can see a barebone example: http://www.olimpo.ch/tmt/tag/tabs/sample_form.cfm You can get the custom tag from here: http://www.olimpo.ch/tmt/tag/tabs/ Massimo Foti Tools for ColdFusion and Dreamweaver developers: http://www.massimocorner.com ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235227 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
Re: maintaining state in multipage form
Why not just pass the values around in hidden fields and then test for them as follows: Put this on the next/prev form pages Put this on the form page checked="checked" /> Change the next/prev links to named submit buttons. If you need to maintain the apprearance of links, then just format them with css to look however you want ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235226 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
Re: maintaining state in multipage form
Think I might have the solution - in the session array or list, save each element in the list as [widgetid]|[pagenumber]. Submit each page to the next, appending the session var with the checked widgets' ids, but first REMOVE all widgets from the list that have the submitting page's number. That way, widgets remain in the session var if and only if they are still checked (I'm overwriting the page's contents with each submission, for all intents and purposes.) Thanks much- I'll post again on how well it works... ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235217 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
Re: maintaining state in multipage form
True, but then the user needs to be able to go back to any form page they've been to, uncheck boxes if they want, and have those values effectively removed from the session array... ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235201 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54

RE: maintaining state in multipage form
It sounds like a session variable containing an array of checkboxes and their selected values might be in order. Assuming the user has cookies enabled (or if you pass the session tokens on the URLs) this should be fairly simple to implement. -Justin > -Original Message- > From: Christophe Maso [mailto:[EMAIL PROTECTED] > Sent: Sunday, March 12, 2006 6:52 PM > To: CF-Talk > Subject: maintaining state in multipage form > > I've taken over a web application where at one point, the > user has a long list of items to choose from to be compared > to one another.
