Re: Detecing a Number

If you are getting a number from a user via a form you can use javascript to verify that the user inputed a number... search google -> validating forms that should give you some info. You could also verify that the data is a number by is_numeric or is_int... I think that when the data is POSTed that it will be a string so you can use is_numberic to verify if it is... http://www.php.net/manual/en/function.is-numeric.php On Wed, 2002-12-04 at 14:01, Stephen wrote: > I have a repeating function to add.
