RE: Validating Checkboxes
I always use ifDefined("form.checkbox") to see if the box was checked.
Using CFParam seems (very slightly) more error prone to me.

RE: Validating Checkboxes
I always use code like
input type="checkbox" name="TheCheckbox" value="1"
and in the processing page
cfparam name="TheCheckbox" default=0
and I've never had any problems with it. Mind you, I haven't tested any
sites with Nutscrape 6 yet...

RE: Validating Checkboxes
The value is held in the value= portion of the cfinput tag and can be
referenced after a submit as form.name where name is the name= portion of
the cfinput tag.
cfinput checked=#chk# type="Checkbox" NAME="location"
VALUE=#intLocationID# #strLocationName#, #strStateAbvrIDFK#
If you have several dynamically generated checkboxes (which sounds more like
what you were asking) and you want a quick check you can do the following.
May be more useful on a validation page
cfif listLen(location) eq 0
code here (i.e. tell the user they must check at least one check box)
cfelse
other code (process the boxes that were checked)
/cfif
or you can use this (more likely on a processing page)
cfif #IsDefined("form.location")#
cfloop index="LName" list=#form.location#
processing code here
/cfloop
/cfif
You could set the value initially to "no" with a cfparam then if the
checkbox gets checked, the value will get changed to the value in the
cfinput tag but given the above examples, this seems like a waste of time.
Not sure exactly what you're looking for, if none of the responses you've
gotten so far have helped, rephrase your question and give an example / some
code. If you get your answer, post a thanks so people won't keep trying to
answer. An example / code may lead to other options like radio buttons etc.

RE: Validating Checkboxes
You might need to post the snippet of code for the submit and action pages... Radio and Checkboxes if nothing is selected do not get passed back to the server. cfparam name="Checkbox_Name" default="" will only set it up as null if its not already set up. But as for validation, what do you mean by this. Do you mean validate that it exists, validate the data or something completely different:-) -Original Message- From: Roque,Carlos [mailto:[EMAIL PROTECTED]] Sent: 23 February 2001 09:45 To: CF-Talk Subject: RE: Validating Checkboxes I am trying to pass a value if when a box is selected.

RE: Validating Checkboxes
Bad news using ListContains... because this list contains 3 103,33,13,23,53 do a ListFind.. 3 will not be found in this list. 103,33,13,23,53 Heath -Original Message- From: sebastian palmigiani [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 21, 2001 2:38 PM To: CF-Talk Subject: Re: Validating Checkboxes on 2/21/01 1:07 PM, Phoeun Pha at [EMAIL PROTECTED] wrote: Anyone have a good method in CF for validating checkboxes (grouped).
