Question

In a form, there are radio buttons for the user to select:

<li>
<label for="full professor"><span class="required">&##8727;</span>Is the candidate a full professor?</label>
    <input type="radio" name="fullProfessor" value="yes" tabindex="4" />Yes<input type="radio" name="fullProfessor" value="no" tabindex="5" checked/>No                                            </li> 

<li>
<label for="more than ten"><span class="required">&##8727;</span>Has the candidate been here for more than 10 years?</label>
<input type="radio" name="moreThanTen" value="yes" tabindex="6" />Yes<input type="radio" name="moreThanTen" value="no" tabindex="7" checked/>No                         </li> 

 <li>
<label for="past nominee"><span class="required">&##8727;</span>Has the candidate been nominated for this award in the last 3 years?</label>
<input type="radio" name="pastNominee" value="yes" tabindex="8" />Yes<input type="radio" name="pastNominee" value="no" tabindex="9" checked/>No                         </li> 

I’m not certain how to param them. The typical code I use is:

    <cfparam
    name="FORM.fullProfessor"
    type="string"
    default=""
    />

Is the type string even though it doesn’t accept a string like a textfield would?

To validate the radio button, is using:

        <!--- Validate campus address. --->
    <cfif NOT Len( FORM.fullProfessor)>
        <cfset ArrayAppend(
            arrErrors,
            "Error message here."
            ) />
    </cfif>

Lastly, maintaining the users’ selection after validating the page, how may I ensure this?

<cfif isDefined(form.fullProfessor) selected="yes">?

Thanks.

If you are using Yes and No you can treat them like booleans.

<cfparam
name="FORM.fullProfessor"
type="string"
default=false
/>

and

 <cfif NOT FORM.fullProfessor>
    <cfset ArrayAppend(
        arrErrors,
        "Error message here."
        ) />
</cfif>

and

<cfif form.fullProfessor selected="yes">

You could also use a framework for validating your forms, I’d highly recommend validate this: http://www.validatethis.org/
