The easiest way with more modern versions of ColdFusion is to use the CFFORM
tag (in place of the standard HTML form tag) and specify the
preservedata="yes" attribute. Likewise, use the ColdFusion input tags such
as CFINPUT in place of the HTML input tag, etc. ColdFusion will keep track
of the form variables and pre-fill the form values for you when the page is
re-generated.
If you want to do it yourself, the method you described is the way to go,
and it is tedious. For checkboxes specifically, they are only submitted if
they are checked, so if you have ONE checkbox with a given name, you can use
the isDefined() function to see if it exists (i.e. <cfif
isDefined('form.somefield')>checked="checked"</cfif>). If you have multiple
checkboxes with the same name, the field will exist if any one of them is
checked, so you'll need to check for existence AND the specific value (or
CFPARAM it to be blank and just check for the values).
I hope that all makes sense. Cheers!
