so this is the best way for all datatypes?

null=”#NOT structKeyExists(arguments, ‘age’)#

@Eric – This would indeed work for varchars, not sure what went wrong for you. Do you have a code sample?

For radio buttons you could replace len(trim()) with isDefined(“myRadioButton”)

Hope that helps.

You also need to mention that this is not for radio boxes. Spent a good deal of time finding this out the hard way.

Thanks,
Eric

Will this work for a varchar field also? I tried using your example and just replaced your field name and the data type and it’s not working.

Thanks,
Eric

@Tracy – Yep, the last example in the post details that.

There was a problem with the syntax highlighter I was using so I don’t think it was displaying correctly.

I’ve removed the highlighter for the last example and just left it bold.

Thanks

Note that (at least with CF8), there’s no need for using YesNoFormat() — like all other CF tag attributes that expect a boolean value, all the usual CF booleans will suffice (0/1, no/yes, true/false). So a simple …null=”#NOT structKeyExists(arguments, ‘age’)#”… will do the trick. I would expect this to be true of all CF versions, but only have CF8 ready to hand.

I tend to use
, which I think compiles to the same thing on the backend. I ran some fairly extensive speed comparison tests between eq “” and not(len()) a while back and came up with the same numbers, though that was on CFMX 6.1, things may have changed in 7
