Loading a model automatically on all pages?

[eluser]Mischievous[/eluser]
I am creating a shopping cart/cms with codeigniter and I am curious on how I could go about loading up a mini-cart that will be show on all pages through the sites that shows the number of items in a cart as well as the total of the cost of the current items in the cart
(ex: 2 Items ($123.97))...

I don't need help on having this information display... just curious as a quick way to load a model throughout the entire system to have it generate the needed information?

Something like an autoload model but i would need the function to run to inject the information into the template? Without having to place this on every function in the controllers to run???

You can extend the Model class to have methods you want to use throughout the site.

You can read up on it under Extending Core Class at:

Could I setup a hook to essentially do the same duty?
