Maybe this is already passed on the list, but if so I mess it. I use this regular expression to validate amounts in my application.
define("VALID_AMOUNT","/^(-?[0-9]+)(\.[0-9]{2})?$/");
Allows numbers, with optional 2 decimal digits and may be also a
negative number.
If someone would like it, he can take it and if someone want to include
it in the cake framework (maybe an improved form), can do it.
