forms, radio buttons and setting values

[rob c]

Hi

I'm not sure if this is the right place to ask for help on forms and radio
buttons...

In the following form, I'd like to set the value of 'item_name' based on which
radio button was selected.
If amount=14, then I want to set item_name='5x7 print'.
If amount=20, then I want to set item_name='5x7 print (drymounted)'.

<form target='paypal' action='https://www.paypal.com/cgi-bin/webscr'
method='post'>
<input type='hidden' name='add' value='1'>
<input type='hidden' name='cmd' value='_cart'>
<input type='hidden' name='quantity' value='1'>
<input type='hidden' name='on0' value='Image'>
<input type='hidden' name='os0' value=362_0515'>
<input type='hidden' name='item_name' value='5x7'>

<input checked type='radio' name='amount' value='14.00'>
<input type='radio' name='amount' value='20.00'>

<input type='image' src='../graphics/cart-add.gif' border='0' name='submit'>
</form>

The live form is here:

<input type='radio'

name='amount'

You won't be able to prevent clever people from selecting the $14 item, but then
setting the value of item_name to '5x7 print (drymounted)' before submitting the
form.

Visitors who don't have Javascript enabled might end up being charged for
mounting, but not having the item_name updated to reflect their choice.

Thanks for the help!!!

I used the <form ... onsubmit...> method with a slight change to my original
idea.

I decided to leave the item_name variable unchanged after discovering that
PayPal has a second set of 'option values' (on1 and os1). So I added:
<input type='hidden' name='on1' value='Dry Mounted'>
<input type='hidden' name='os1' value='not set yet'>

And the <form> line looks like this:
<form target='paypal'
action='https://www.paypal.com/cgi-bin/webscr'
method='post'
onsubmit='this.os1.value=(this.amount[0].checked)?"No":"Yes"'>

The results from PayPal show as "Dry Mounted: Yes" or "No". If "not set yet"
appears then there is a problem, maybe I should change that to something like
"there's been an error - please let me know about it".

Thanks again!
