From: David Mehler on 7 Jun 2010 13:49 Hello, I've got a form with two combo boxes, one for the month one for the day. Both are required. I've got code that checks the post submission to ensure neither is empty. My problem is that if a user does not select anything in the combo boxes January first is sent, this i don't want. If they haven't selected anything i'd like that to show as an error. Thanks. Dave.

From: Gerardo Benitez on 8 Jun 2010 11:57 Hi Dave, In general, you can validate this condition with javascript before to send the form, and if some errors exist, the form is not submitted. or validate the conditions in the server side with php.

Javascript validation is nice, but you should always validate everything on the server too. Thanks, Ash http://www.ashleysheridan.co.uk
