Checkbox Selection order

[Phil.]

Hey

I thought i'd be able to find something about this but try as i might I can't find anything remotely useful, maybe I my search doesn't explain the problem very well, anyway..


So I have a bunch of check boxes that go towards creating a report. Each checkouts toggles the inclusion of a particular metric when the form is submitted and the report is run.

I'd like to be able to return the columns in the order in which the check box buttons were checked.

e.g:
Metric Checked Order
A --------------- 2
B --------------- 1
C --------------- 3


Report

B | A | C
----------
X | Y| Z

I was thinking of adding onclick events and getting the name of the checkbox, storing that in an array, or writing it to a hidden text field or something of that kind, but seemed like it would very very messy, hoping a simpler solution could be suggested.

Thanks

Hi

Think using hidden fields populated when the checkboxes are ticked would be how I would do it. Down side is that it means it only works if they have javascript enabled (if that matters to you).

Difficult bit is faffing round removing items when they uncheck a check box.

Failing that simulate a pair of list boxes, one for possible fields and the other for selected fields. Click to move between them (or drag and drop is you are feeling flash). When the form is submitted copy the selected fields to an array of hidden fields to pass back to the server.

All the best

Hey Kieth, thanks for the response.

Ended up using a hidden field. Had contemplated using drag an drops but was concerned it was adding an extra step.

So anyway, incase anyone ever stumbles on this one day and wants some code to look at:

Using the $F function from the prototype Library

Hi

Possible, although you could also use you function to add a hidden field each time. Saves the explode (which has potential issues if the value happens to contain whatever you are using as a delimiter).

All the best
