how to show all items on checkout page

Nov 27 2013 6:58 AM
hello im busy with a practical i got i came quite far using a template as a layout but i have a issue i am facing.

I can add items to a cart all good and well but when i checkout i want to be able to remove unwanted items. i have my code to add the items to a cart i taught myself ajax just to add the items together but on the checkout page i don't know how to show all the items in the cart, i use sessions as well. I'm in my first year so things are still new to me here 

Here is my code :

}


this code is for one of my pages that add items to cart. I don't want answers just some guidance on what tool to use maybe. It's pointless getting answers meaning i don't learn anything.

Thank you in advance
