cfif select option value problem

I have a form with a dropdown box asking users to select where they
heard about my site. The completed form sent to me via email.

The dropdown is optional so if they don't select it I would like nothing
to be returned in the email.

The first option reads "I heard about you from" - I've tried <option
value> <option value=""> and even <cfselect> with various options but I
can't get it to work.

This is what I have for the email:

<cfif isdefined("form.referral")><cfoutput>#form.senderFirst# heard
about you from #form.referral#</cfoutput></cfif>

This is what I have for the select options:

<select name="referral">
<option value="">I heard about you from...</option>
<option value="Google">Google</option>
<option value="Yahoo!">Yahoo!</option>
<option value="Ask">Ask</option>
<option value="MSN">MSN</option>
<option value="a friend">A friend</option>
<option value="somewhere else">Somewhere else</option>
</select>

Thanks Ken - that worked perfectly! The Trim function is especially
appreciated.

See dempster's <cfloop> checkbox answer below. Extremely elegant to say
the least :)

Radio buttons and checkboxes are the only form elements that do not have a default value, so the others will always be defined.

<cfif IsDefined ("form.senderPhone") AND Len(Trim(FORM.senderPhone)) GT 0>
<p>Phone: <cfoutput>#form.senderPhone#</cfoutput></p>
</cfif>

<cfif IsDefined("form.senderMessage") AND Len(Trim(FORM.senderMessage)) GT 0>
<p>Message:
<cfoutput>#ParagraphFormat(form.senderMessage)#</cfoutput>
</p>
</cfif>

Probably a more elegant way to do this but I can't think of it right now.

<cfparam name="FORM.webSiteDesign" default="no">
<cfparam name="FORM.graphicDesign" default="no">
<cfparam name="FORM.logoDesign" default="no">
<cfif FORM.webSiteDesign EQ "yes" OR FORM.graphicDesign EQ "yes" OR FORM.logoDesign EQ "yes">
<p>
Interested in:<br>
<cfif FORM.webSiteDesign EQ "yes">
webSiteDesign <br>
</cfif>
<cfif FORM.graphicDesign EQ "yes">
graphicDesign<br>
</cfif>
<cfif FORM.logoDesign EQ "yes">
logoDesign<br>
</cfif>
</p>
</cfif>

Thanks dempster that worked!

Now I'd like to be able to do the same thing to a phone text box, a few
checkboxes and a textarea.

None of the code below works - they all return messages (i.e. "Phone:"
"Interested in:" and "Message:") even if that field isn't filled out.
I've tried several different variables with no success.

My questions are:

1. Phone - How can I write the cfif so the "Phone:" doesn't appear in
the email if a phone number isn't entered?

2. Checkboxes - The problem here isn't with the boxes themselves, but
with the "Interested in. Currently I have it set to "WebSiteDesign". The
obvious problem here occurs when they check another box, such as
"GraphicDesign". I've tried OR statements with no success. How can I
write a cfif for the exclusion of "Interested in" in the email if no
checkboxes are selected?

3. Textarea - What do I need to change in order for the email not to
display "Message:" if no message is entered?

Here's the code:

PHONE



<cfif IsDefined ("form.senderPhone")>
<p>Phone: <cfoutput>#form.senderPhone#</cfoutput></p>
</cfif>



<cfinput type="Text"
name="senderPhone"
message="Please enter your area code and phone number."
mask="999-999-9999"
validate="telephone"
validateat="onsubmit,onserver"
size="30"
maxlength="16">

CHECKBOXES



<cfif IsDefined("form.webSiteDesign")>
<p>Interested in:</p>
</cfif>

<ol>
<cfif isdefined("form.webSiteDesign")>
<li>Web site design</li>
</cfif>
<cfif isdefined("form.graphicDesign")>
<li>Graphic design</li>
</cfif>
<cfif isdefined("form.logoDesign")>
<li>Logo design</li>
</cfif>
</ol>



<p class="boxes">
<cfinput type="checkbox" name="webSiteDesign" value="yes">
Web site design</p>

<p class="boxes">
<cfinput type="checkbox" name="graphicDesign" value="yes">
Graphic design</p>

<p class="boxes">
<cfinput type="checkbox" name="logoDesign" value="yes">
Logo design</p>

TEXTAREA



<cfif IsDefined("form.senderMessage")>
<p>Message:
<cfoutput>#ParagraphFormat(form.senderMessage)#</cfoutput></p>
</cfif>



<textarea name="senderMessage" cols="44" rows="6" wrap="virtual">
</textarea>

It helps to have an understanding of how CGI passes form fields, but basically text input fields and textareas pass a value even if it is an empty string. So the easiest way to check is just look at the length of the field, for example:

<CFIF Len(form.senderMessage) GT 0>
Message: #form.senderMessage#
</CFIF>

Sorry, I overlooked your checkbox question. Two ways to handle this. One is just to extend your CFIF with OR:

<CFIF IsDefined("form.webSiteDesign") OR IsDefined("form.graphicDesign") IsDefined("form.logoDesign")>

The other way is to give the checkboxes the same name and different values:

<INPUT TYPE="checkbox" NAME="interests" VALUE="Web Site Design">Web Site Design
<INPUT TYPE="checkbox" NAME="interests" VALUE="Graphic Design">Graphic Design
<INPUT TYPE="checkbox" NAME="interests" VALUE="Logo Design">Logo Design

In this approach, you can see if Form.interests is defined, then loop through the values as a comma-delimited list.

<CFIF IsDefined("Form.interests")>
Interested in:
<UL>
<CFLOOP INDEX="oneinterest" LIST="#Form.interests#">
<LI>#oneinterest#</LI>
</CFLOOP>
</UL>
</CFIF>

The advantage of this approach is that it's easy to modify by just changing the form.

Why not use something like <option value="X"> and then test this way:

<cfif isdefined("form.referral") AND form.referral NEQ "X">
<cfoutput>#form.senderFirst# heard about you from #form.referral#</cfoutput>
</cfif>
