Sample Model/View/ Controler for inserting data?

[eluser]slaction[/eluser]
I'm working on inserting some data into a database but I'm having trouble putting my model/view/controller together since I'm new to CI and OOP in general.

I can create the HTML form and send it back to a controller but I'm sort of lost from there.

I did watch the video tutorial for making a blog, but my form data doesn't match my database fields like it did in the tutorial so I can't use the same code.

I've looked at a few open source CI apps, but they seem to be doing so much that its hard to pick out the code I need.

Any help would be great. I'm just looking for a good starting point.
