I'll add one more solution to this. The "form" scope in ColdFusion is
actually treated as a structure. This means you can also find the
number of form fields by doing something like this:
#structCount(form)#
Realize, however, that this count will include the actual
"form.fieldnames" variable which doesn't truly get submitted by your
form, but rather gets calculated by ColdFusion and added to the FORM
scope/structure. This means in order to get the count of just the
fields that were submitted, excluding "form.fieldnames", you'd need to
subtract one.
#evaluate(structCount(form)-1)#
Hope this helps,
Tyson

Subject: counting form fields
Is there any way to get a count of the number of fields that are
returned
from a form?
Also, is there a way to get a count of the number of records selected by
a
cfquery? The only way I have found to do that is to do a second cfquery
and use the "count(*)" function, but that seems to be double the work.
In Visual Basic, I can just put ".recordcount" after the recordset name
to
get a count. Does Cold Fusion have anything like that?
Thanks!
