Hii, I have attached a zip file containing 3 files in it. First is the html file containing the front end. Second is the php file which would help in populating the dropdown boxes of the frontend from the DB. Third is the sql db If u'll have a look a the html file i.e the frontend,u will notice that on selecting a particular radio button,some others may get disabled. For eg: If i click on Enter new subject,the buttons above and below it get disabled.And some other options are automatically checked.These options are mandatory. When user fills up the checked options,i want it to go to the DB tables accordingly. I hope i am making myself clear.Incase ur not able to get me,pls reply so that i can clear what i am tryin to say.
