ColdFusion 9: int and type=“numeric” nasty bug?

Question

I\'ve just experienced a behaviour that defies any logic and could potentially lead to serious issues and was wondering if it was a bug or if the behaviour was itend

Answer 1

You can use regular expressions to find out if there are any non numeric characters in a given form field:

reFind( "[^\d-]", "1 2")

That will match any character that is not a number, not a -

If you want to check only positive numbers, you can use

reFind( "[^\d]", "1 2")    

If this returns true, you do not have an integer.
