Well since it is dug up anyway, may as well capitalize on it!

Can someone explain the difference between HMVC and MVC and what ‘module’ is referring to in this context?

H = Hierarchical, meaning the MVC (Models-Views-Controllers) are located within a hierarchy (aka modules)
HMVC allows you to do something like this

Therefore, your application is more portable.

I can see how it makes them more independent, but doesn’t that make code less re-usable?

I’m not sure how it could make it less re-usable.

I think that Matchbox/HMVC simply alters CodeIgniter’s lookup chain; Everything works like a vanilla-CI does. I could be wrong though.

What I mean by less re-usable is that lets say you have function X() that does something with users and that is in the polls module.  Now in the forum module you need to do the exact same thing.  In order to make the two portable you would have to have two copy’s of the function one for each module thus sacrificing re-usability for portability.

Someone correct me if I am wrong!

It dosn’t mean every possible problem can be made re-usable, but say you made an Asset Library and put it in a module. If it was made so it didn’t rely on anything else than you can drop it in and out.

Now I personally use modules for a better separation. In BackendPro I use it to separate out most of the code so the application dir is left for the user to add their controllers without all the ‘gubins’ cluttering it up. It then means by seperate parts of the application are in nice manageable chunks.

Don’t forget you can still put libraries and models in the root folders for easy sharing and Matchbox can use syntax like $this->load->module_model(‘modulename’, ‘modelname’); anyway. All code is still accessible just separated better.

this something that’s not in the CI masterplan? I know, we can use Modular Extensions or Matchbox, but I was just wondering if it’s something you’re planning as a structural part of CI itself.

Thanks & Regards
