My personal favorite version is:
<cfparam name="variable" type="string" default="">
<cfif len(variable) neq 0>
#variable#
</cfif>
- j

Subject: if value exists, show it
I simply want to test to see if a variable has a value (eg text has been
returned from a query) and if so, show it. There seem to be a few options --
<cfif isdefined(#variable#)>
#variable#
</cfif>
or
<cfif len(#variable#) GT 0>
#variable#
</cfif>
or
<cfif #variable# IS "">
#variable#
</cfif>
Is one of these better than the others for dealing with text values? I
understand that IsDefined should be locked; I assume that is not the case
for the other two.
TIA,
Trey
