Re: Determine if a variable has a value

Hello,
I am new to ColdFusion, so this will be an easy answer to most of
you. I am having difficulty trying to determine if a variable in
one of my pages has a value. What I mean by a value is did I assign
it a value or is it still empty. I have tried using IsDefined,
Evaluate, and other CF Functions, but they all are failing the test.
Any ideas on how to quickly and easly determine if variable has a
value.
Thanks in advance.
If you know the variable is set:
cfif myvariable is not ""
if you're not sure if you even set an empty default variable:
cfif isdefined('myvariable') and myvariable is not ""

Re: Determine if a variable has a value
I usually use CFPARAM NAME="varname'" DEFAULT="" Then just check the value with CFIF varname IS "" There are other ways but this will work. Dustin M.

RE: Determine if a variable has a value
Hi Michael,
I know you have tried it, but isDefined("variablename") is the basic method.
The quotes are a common trap. COuld that be your problem?
Good luck,

RE: Determine if a variable has a value
IsDefined("MyVariableName") is what you want.
