[thelist] CF Radio Buttons Tip

[Joshua OIson]

It's always nice to get tips for automating tedious tasks.  Some of the
newer versions of ColdFusion introduced functions and tags that may even
make the tasks easier.  The code you gave could be replaced with the
following:

<!--- list radio button names in a variable --->
<cfset checker = 'one,two,three,four,five,six,seven,eight,nine,ten'>
<!--- loop through them --->
<cfloop index="next" list="#checker#">
  <cfparam name="form.#next#" default="">
</cfloop>
