form.fieldNames "missing" fields

[ufitzi]

I have discovered during recent testing that certain field names are not included in the form.fieldNames list,
In particular, I had a form that included text input fields named "event_arrival_date" and "event_departure_date."
Upon submitting the form, the values of these two fields COULD BE OUTPUT, but WERE NOT included in the form.fieldNames variable. I tested using FireFox 2.2 AND IE 6, so I'm assumming this is a ColdFusion problem.
Upon removing the "_date" portion of the filed names, they were included in the fieldNames variable.
Can anyone explain this bug? Security feature?

Hi,

_date, _cfformdate, _eurodate, _cfformeurodate and _cfformusdate all are part of Coldfusion's way of validating a form using the predefined hidden fields... So you cant suffix this values in your element names.. Its actually a feature and not a bug..

Daverms,
Thanks for the info.
My only complaint would be the lack of a CF error page indicating the problem.
Instead, the fields are just left out.
This poses a problem to those who have coded their processing page using the FORM.FIELDNAMES list and <CFLOOOP>.
In any case, thanks for the response!
"Security feature?"...I DID acknowledge that possibility!! :-)

You could always loop through the form collection instead ;-)

<cfloop collection="#form#" item="fieldName">
<cfoutput>#fieldName#=#form[fieldName]#<br></cfoutput>
</cfloop>

Try using a <cf_dump var=#form#> to see what's really being sent by the form
