dixcoder has shown you above how to delete an id using CodeIgniter's Active Record.

You need to read the CodeIgniter user guide here

Database:

Database

As far as your view, you need to read the CodeIgniter form_helper here:

Form Helper

Then read the CodeIgniter Form Validation here:

Form Validation

No one is going to write the whole code for you, you need to start reading the CodeIgniter user guide and try to do a lot of these things on your own!

If you have a specific problem then I am sure that lots of users on here will help you out but to code the whole thing for you I doubt it.

Enjoy
