[php]Making User Subscribe to diffrent things by drop down menus

Well, Im working with a few other people on a school site and im wondering if it's possible to actually make a reg form that would sign you up, but lets say your in a specific grade + group, it will automaticly insert you into that group. The sites supposed to give you the class homework and other things like news and other stuff. So i wanna know if you can make it subscribe to certian things while making a user.

Yah... they just select what grade they're in.
If you want to check it then you have to have a database beforehand to reference.

Yes it's possible but it depends on a few factors.

There's few different methods to do it, one of is using database like what Wh005h said, another method is just on the php code itself.
