Best way to make Admin pages in CodeIgniter?


I'm working on an app in CodeIgniter, and I want to have admin pages for several of the objects in the application, and I'm wondering what would be the better way to put these into an MVC structure.

Idea 1: In each controller, have an admin function, and add all of the admin pages I would like into that function. example URL:

Idea 2 Make a new admin controller, which would have to reference many different models, and put all of the admin pages in there. example URL:

Which way would be better?

Edit for clarification: By admin functionality, I mean being able to do the basic CRUD actions on any object, and be able to display a list of all of said object.

I'll echo Justin in keeping it part of the individual controllers.

You should setup some kind of authorization system that the individual controllers can use to so who is logged in (username) and what access they have (admin/member/etc). Here's a SO thread on CodeIgniter Auth Classes.

The view would then conditionally show the appropriate links, and the controller would enforce the policy by checking the auth before passing any data to the model or rendering an edit view. On unauthorized access an error could be rendered, or simply render with the non-editing view.

This approach seems to make the most sense (at least to me) because all the functionality is stored in the individual controller. Keeping admin functions in a single admin controller means you'll have to manage two controllers (the admin, and the actual controller) every time you add somethign new (or remove something).

If you're concerned about putting auth checking in every controller, you could create a generic controller class with all the auth setup, then have your controllers extend it. In the end the individual controller auth check could be as simple as:

function edit()
        //display auth error, or forward to view page

Of course some kind of ACL implementation would make this better, but I don't believe CodeIgniter has an 'official' ACL.

Definitely a different controller at least!

I used to think that I could keep all my admin functions in a single controller, but as my programs grew, I realized that I needed multiple controllers in my administration section.

So, I created a folder inside my controllers folder with the name "admin" and put all my administrative controllers in there. So my folders would look something like:

  • application
    • controllers
      • front.php
      • welcome.php
      • admin
        • dashboard.php
        • useradmin.php
  • etc...

One problem this creates, however, is when you type in your browser, it returns a 404 page. So, go to your "application/config/routes.php" file and add a custom route:

$routes['admin'] = 'admin/dashboard/index';
