On a side note, if you're after an output of 'yes' or 'no', this may be cleaner:

Thanks. I'm actually after the structvalue if it exists and a zero length
string if it doesn't. It looks like Rex has me sorted though. Thanks Dom.

If my var y = myCell and I want to know if the key myCellHead exists
in a struct how do I do it? I thought that the following would work in an
IIF statement but it doesn't.
iif(StructKeyExists(x.classAssign,#y#head),DE('yes'),DE('no'))
Any ideas?
This should work fine:
cfif structKeyExists(somestruct, #y#head)
You don't need IIF at all.

I know, but I want it inline of an html tag, so that's why I wanted IIF
instead of an if/else block.

It works for me:
cfset x = {}
cfset y = all
cfoutput
#iif(StructKeyExists(x,#y#head),DE('yes'),DE('no'))#
/cfoutput
p
cfset x[allhead] = 1
cfoutput
#iif(StructKeyExists(x,#y#head),DE('yes'),DE('no'))#
/cfoutput
I correctly get no/yes.

Here's what I have:
#iif(StructKeyExists(x.classAssign,#y#head),DE(x.classAssign[#y#head]),DE(''))#
The error I get is:
Element NAMEhead is undefined in a CFML structure referenced as part of an
expression.
Since I couldn't get it working I switched it to an if/else statement and
got the
Looks pretty similar, but mine works:
cfset x = {}
cfset y = all
cfoutput
#iif(StructKeyExists(x,#y#head),DE('yes'),DE('no'))#

cfset x[allhead] = booger
cfoutput
#iif(StructKeyExists(x,#y#head),DE(x[#y#head]),DE('no'))#
/cfoutput

Try running this:
cfset x = {}
cfset y = all
cfoutput
#iif(StructKeyExists(x,#y#head),DE('yes'),DE('no'))#
/cfoutput
p
!--- cfset x[allhead] = booger ---
cfoutput
#iif(StructKeyExists(x,#y#head),DE(x[#y#head]),DE('no'))#
/cfoutput
Bah - I hacked away at it for 10 minutes before remembering why I
hated IIF/DE in the first place. ;)

HA! So I'm not the only one!
So I thought DE meant Delay Evaluation as in Don't evaluate what's in
these little brackets this until you've satisfied the IIF condition.
I guess not?

CF9 has the ternary operator which is awesome. Works like JavaScript:
cfset output = (boolean ? It was True : It was False)

Subject: Re: Finding if a key exists
Unfortunately I'm on CF8. And I wonder if the ternary operator would be able
to handle a dynamic value as the output as with my example. IIF works
perfect for exactly the type of example you gave; a simple boolean evaluated
to output a simple string. The problem lies in CF apparently evaluating
A lot of people get DE() wrong.
IIF does not short-circuit
(http://en.wikipedia.org/wiki/Short-circuit_evaluation), meaning that
your DE() gets evaluated even if the condition is FALSE. So, this will
break:
#iif(false, notFalse, false)#
since notFalse does not exist. Same here:
Wow. I had no idea you could wrap DE in Evaluate. Did you come figure this
out through trial and error or have I just never read it?
Thanks for the post rex.

So I went back and read the docs for IIF. I haven't looked at them in years
and I'm shocked that I've used it for SO many years without really
knowing exactly how it worked. I would've first read about IIF pre version
5. I can't even find the docs for it. Version 5's description is a little
16 matches
