Radio Buttons w/ Multiple Values on a PHP Form

Question

Hi,
I have an Online Registration form with several options that each have their own prices.  I want the form results to show the name of each option the user selects, and the total of all the prices combined.  My question is how can I do that when each radio button only allows you to attach one value?  Is there a way to somehow retrieve the option name and price as two separate values?
<input name="option" type="radio" value="Cotton - $10" />
<input name="option" type="radio" value="Suede - $15" />
<input name="option" type="radio" value="Leather - Black - $20" />
<input name="option" type="radio" value="Leather - White - $20" />
For example, if they select 'Leather - Black - $20" I want to be able to retrieve one value of "Leather - Black" and another value of "20.00" (to add to the total price) rather than simply "Leather - Black - $20" in one value.
Any help would be greatly appreciated!  I've only had to deal with one value for each radio button in the past.
Thanks!

Yes you can do this.  If I were you I would eliminate the space in the value just to eliminate confusion.  Then when you process the variable use the Explode function ( http://php.net/manual/en/function.explode.php ) to separate the values in your string.  So if you eliminate the space your code would look like:
$_POST['option'] = $option;
$option = explode ("-",$option);
print $option[0]; //This would print the material
print $option[1]; //This would print the price
The only trick is your first two options don't have a color.  So your arrays would be different.  To offset this I would recommend that you use the same format for all options and make some sort of null value if nothing will be added for one value in the array, ie: color.
