IsDefined

At server side I want to check form collection or Url collection. I used
cfdump to know content of "FORM" and "URL" , it shows me struct[empty
strings]. How I would determin these structures are empty?

I used isdefined("FORM") but it is not working. Is there any way to determing
FROM and URL string are empty or set?

Thaks in advance

structkIsEmpty() OR structCount() will probably work for what you want.

I believe the FORM and URL structures always exist. To determine if they are empty, try the StructIsEmpty function.

Well they always exist, so that's not the best approach.

Have a read through the docs for functions relating to structures.
structCount() is probably the closest one to what you're asking. Or
structKeyArray() or something.

Thanks a lot ...

Form and url structure not exist if you visit server side processing page
directly. So before refering these varaibles code you have to varify there
existance.

I check with structIsEmpty() but it didn't work out . Getting soem java.map
interface error. I achives same result by checking
isdefined("form.fieldnames"). But this doesn't work for URL.

Anybody having any idea how to verify URL is empty or not?

Thanks

This doesn't work for URL, when form posted with "GET" method then
len(cgi.querystring) is zero.
Also Why I am getting an error The value of the parameter 1, which is
currently "URL", must be a interface java.util.Map value while checking
StructIsEmpty("URL")

I don't understand what you mean by that. As opposed to "indirectly"?

1. data input form cfm
2. data process from cfm

Thanks !!

Ther is possiblity in my application user come to data process form without
visiting data input form. In that case my application throwing an error beacuse
I am not verify Form and URL filed are empy.

so my question is how do we check weather FORM and URL contain any fields or
not. I found soln for FORM but not for URL. The URL doesn't have property like
fieldnames.

So question here How do you identify URL contain anything or it is a blank.

p.s. My application problem can be resolved other ways i.e. by checking http
referer or there are other ways around...

Thanks in advance ..
