<cfif isdefined is not working

[swapna]

I am using cold fusion 8 to develop forms. I need to check if user has entered a value of type "text". If not then a message has to Cfoutput. i am using the following code:

<cfif not isdefined("form.question")>
<cfoutput> Enter question
</cfoutput>

</cfif>


The problem is even f nothing is entered in the Question Field, the message Enter question is not being displayed. Its as is the <cfif not isdefined("form.question")> is not at all being recognised.
I also tried <cfif not isdefined("form.question_now")>

Please help.

Hey there,

Try this:

<cfif not isdefined("form.question") OR #form.question# EQ "">
<cfoutput>Enter question</cfoutput>
</cfif>

Your problem is when the form is submitted the question variable is defined, but it is set to an empty string.

Sincerely,
