I agree that seems a little wonky. I ran the code below to test some
values with ColdFusion 9 and the results are included in the inline
comments:
<cfoutput>
$123,123.00 = #isvalid("integer", "$123,123.00")# <!--- NO ---> <br>
123,123.00 = #isvalid("integer", "123,123.00")# <!--- NO ---> <br>
123,123 = #isvalid("integer", "123,123")# <!--- YES ---> <br>
$123,123 = #isvalid("integer", "$123,123")# <!--- YES ---> <br>
4,123,123 = #isvalid("integer", "4,123,123")# <!--- YES ---> <br>
4,123,123,123 = #isvalid("integer", "4,123,123,123")# <!--- NO ---> <br>
123,,123 = #isvalid("integer", "123,,123")# <!--- YES ---> <br>
</cfoutput>
It will accept the dollar sign ("$") and even a double comma (",,") as
part of an integer value, but not a decimal point (".00"). I can see
how that would be frustrating as I would expect it to handle some of
those differently. I've been sanitizing integers on my own since
ColdFusion 4, so this isn't something I've really bumped into. I do
use isValid() for verifying e-mail address formats in some places, so
I'm beginning to wonder what problems exist in that algorithm, if any.
Hmm...
