Working on database update

I have worked a little on creating a web based database update program. Right now I have to go into phpMyAdmin and make all the changes. This requires passwords and such. I want to have it set up so people who are authorized can easily add projects or add information about projects.

I have a simple page that shows the fields to modify. It goes to a page that could write the information, but it doesn't yet.

I also need to get something to sign in so only authorized people can change things.
