Hi there people

Is it possible to change the name of a text field with radio buttons.
I picture three radio buttons, and a field which name will change according to which radio button is checked.

I think maybe this should be done roughly like this (pseudocode):

<input type="text" name="variable">
onSubmit =
if radio1 checked: variable = name1
if radio2 checked: variable = name 2
...

or maybe it is better to do it another way?
I'd appriciate some help in this matter.

If you change the name of the field client side it makes it a little more complicated when recovering the submitted data.

Explain why you want to do something like this and there probably will be a solution.

I'm making an ordering form for a take away buffet resturant.
The customers can choose menu size (small, medium, large) and for how many people the order is.
I already have a shopping cart script which I have modified and am happy with it.
So there are actually 3 items to order (small, medium and large), but there will only be 1 field for entering quantety, and the item will change according to which radio button is checked

So if radiobutton1 is checked I want the the form to submit a textfield with the value X and name A. If radiobutton2 is checked I want the form to submit a text field with the value X and name B.

The php script i use, uses the form name to recognize which item has been ordered.

Istead of this:
Small [ 0 ] (name=A)
Medium [ 5 ] (name=B)
Large [ 0 ] (name=C)

I need this:
Qty [ 5 ]
Size: oSmall ¤Medium oLarge

I cant seem to find a good solution to this.

maybe use a hidden field called size and set the value accordingly
You need to cover radio buttons onClick event and the onBlur event for the text field

Thanks for all the help!
I figured it out using php.

definitely the best option IMO
