Prevent a date from happening in the past I have a CCK field that is a date. I want to prevent people entering a date that has happend in the past. I know you can set Years back and forward and I have set this to -0:+2 but this just limits the calendar. Any ideas what I can do?
Drupal's Form API allows you to add your own validation functions to a form. There is an example for a date field validation function in this forum topic. Documentation is here.
