Dave is right. Also, when CI 1.7.1 was the newest version, it was correct to extend Controller . Versions 2+ should be extending CI_Controller.

@ Jongosi – The filenames are the same as the class names, the first library file, goes into application->libraries, and the controllers go into application->controllers.

gonna try this out now, but shouldn’t extends Controller br ‘extends CI_Controller’ ?

Comment on Update any index in CodeIgniter Cart class by Otuoma Sanya

Sorry for the bother but the script works fine, I had included an array value and that is why I was having the trouble. Again, thank you!

Comment on Update any index in CodeIgniter Cart class by Nelson

Otuoma, as you’ve found, the reason for the undefined function CI_Cart is that CodeIgniter 2+ is built for PHP5 and has removed older PHP4 functionality. You did the correct thing by changing parent::CI_Cart(); to parent::__construct();

With that said, I do not know why the cart is not updating as expected. I have just updated the extended cart class to CI 2.1.0 and had no problems getting the sample application to work. During the upgrade, the only things I changed were the parent call in the controller and the class itself. Maybe you could review my use of the class in the updated sample application and identify what you are doing differently?

I am trying to use this method on a project. However, when I use it as per your instructions, I get the error : Fatal error: Call to undefined method CI_Cart::CI_Cart() in C:\xampp\htdocs\benta-pos\application\libraries\MY_Cart.php on line 9.

When I change the constructor to:
function __construct() { parent::__construct(); }
Then the cart does not update and I get the same cart contents.

I am using CI 2.0.3
Do you have any solution for this?

Comment on Zip code library in CodeIgniter by Nelson

Jason, the latest version in my BitBucket account will work with CI 2.0, but I do not know if it will work without modification to 2.1.0. If it doesn’t, it will probably not be too difficult to fix.

The data in the included dump is not up to date. It has most of the geographic data, but I believe there have been some zips added since the data was collected.
