I was wondering how to do this. I have a field on my web page that is for dates. I also have a calendar next to it that the user can click and a pop up calendar appears. The user then only needs to click on the day they want and the pop up disappears and the date is entered into the field. The problem I am having is that some users decide to enter their dates in manually and some of the formats the database can't recognize. I was wondering if I could somehow lock the input box that the date is stored in so that the user must use the calendar. I tried to disable the field but now it won't accept any date from the calendar. Any ideas?
