Return data from Checkbox for a newbie

[jeniferdesign]

Here is my input tag:

<cfinput type="checkbox" name="checkbox1" id="box1" value="datafrom1" />

<cfinput type="checkbox" name="checkbox2" id="box2" value="datafrom2"/>

<cfinput type="checkbox" name="checkbox3" id="box3" value="datafrom3" />

Action page:

Is checkbox1 checked #IsDefined("form.checkbox1")#
Is checkbox2 checked #IsDefined("form.checkbox2")#
Is checkbox3 checked #IsDefined("form.checkbox3")#

But all says yes whether the checkbox is checked or not.

I know the answer is simple, but I am very new.

Do you have anything else on the actionpage? CFParams for example?

[jeniferdesign]

yes, it's rather long because there is other data, but yes..should I add this line for each checkbox?

<cfparam name="FORM.checkbox1" default="">

[Joshua_Cyr]

if the cfparam for the form is there then it will always be defined.

So instead you can check for the default value vs the checked value.

[jeniferdesign]

Okay, now I have

<cfparam name="FORM.checkbox1" default="">

for each checkbox.

What should my output tag say?

[Dan_Bracuk]

The syntax for outputing form variable is

<cfoutput>#form.something#</cfoutput>

What you should output in your particular case depends on what you are trying to accomplish.

Thanks Dan.

I am not a developer, so I'm struggling here:

I simply want to display what checkboxes were checked, sent to me in an email.

This is what I have so far:  I receive the information I want except whether any of the various checkboxes were checked.

What do I use to display the checkbox info

<cfmail
        from="xxx@dotcom"
        to="xxx@dotcom"
        subject="Subject Application "
        server="">
   
   
    Name: #Trim(FORM.Name)#
    Phone: #Trim(FORM.Phone)#
    Email: #Trim(FORM.Email)#

  </cfmail>

The easiest and most basic way to *probably* do what you want to do is to name all your checkbox controls the same.

I.E.

<input type="checkbox" name="myListOfBoxes" value="Blue"/>

<input type="checkbox" name="myListOfBoxes" value="Red"/>

<input type="checkbox" name="myListOfBoxes" value="Green"/>

Then on the action page.

<cfparam name="form.myListOfBoxes" default=""> <!--- Easy way to handle if NO checkboxes are selected --->

<cfoutput>#form.myListOfBoxes#</cfoutput> <!--- Outputs a list of colors selected, empty if none are checked --->

Thanks ilssac!  Works like a charm.

If you want the actual values:

Action page:

checkbox3 = not checked!
