date validation problem!

Hi all: I am having some problem with date validation I am trying to validate the date in a form Field I had provided a text field for date, so have to expect all the different possible entry, When i tried with checkdate() method it needs the parametes in (int month,int date, int year). It make the code more complex , What i am looking is some thing similar to is_int(), like the one we have in VB isdate() thanks in advance Prad __________________________________________________ Do you Yahoo!?
