Dynamic Radio Button Group in Coldfusion

Question

The user will input their Id number then the accounts tied to this Id number will be presented(radio buttons) . They could have 1 or even 10 accounts returned(radio buttons). I need to have them update their account to a Y, N. The account Id is what makes up the radio groups. Now I need to know who to loop through these radio buttons to see what they selected.

<cfif isDefined('FORM.bnt2')>
    <cfloop index="i" list="#form.fieldnames#">
        <cfquery  name="accept" datasource="#request.dsn#">
            UPDATE opt SET 
            f14 = '#evaluate(i)#'
            WHERE f4 = '#FORM.id#'
        </cfquery>
    </cfloop>
</cfif>                                                              

<cfform  name="frm2" id="form2" method="post" action="">
    <cfinput type="radio" name="#f5#" value="y"> 
    <cfinput type="radio" name="#f5#" value="n">
    <cfinput type="hidden" name="id" value="#f4#" />
    <cfinput name="bnt2" type="image" class="btn" src="images/accept.gif" value="Submit"/>

Answer 1

Don't use evaluate!

Do use cfqueryparam!

And fix those variables names, f5, btn2 etc are not good names.

Anyway, I'm not entirely certain what you're doing, but here's a code snippet for you:

<cfoutput>
<cfloop index="CurField" list="#Form.FieldNames#">
    <br/>#CurField#=#XmlFormat(Form[CurField])#
</cfloop>
</cfoutput>

That should give you what you need to make things work.

Note the XmlFormat is for display - generally not done in queries (storing data in the database), but instead when it is displayed to a browser. (Can also use HtmlEditFormat if you prefer.)

Answer 2

Thank you all for your help, here was my final solution.

<cfif isDefined("FORM.bnt2")>
<cfloop index="id" list="#form.listofids#" delimiters=",">
<cfquery  name="accept" datasource="#request.dsn#">
UPDATE opt SET
F14 = '#Evaluate("form.select_#id#")#'
WHERE f5 = '#id#'
</cfquery>
</cfloop>
</cfif>


<cfform  name="frm2" id="form2" method="post" action="">
<cfoutput query="accountCheck" >
<cfinput type="radio" name="select_#f5#" value="y" required="yes" validateat="onsubmit" message="A value of Yes or No is required.">
<cfinput type="radio" name="select_#f5#" value="n" required="yes" validateat="onsubmit" message="A value of Yes or No is required.">
<cfinput type="hidden" name="listofids" value="#ValueList(accountCheck.f5)#" >
</cfoutput>
<cfinput name="bnt2" type="image" class="btn" src="images/accept.gif" value="x"  style="float:right;" />
</cfform>
