I am building a website with a basic shopping cart function. The following line of code lists each of the potential 6 items in the list and I have a function called listCart() which gets a total number of items (again maximum 6) in the cart.
<?php (print_r($_SESSION['cart']))?>
I want to be able to iterate through each element in the cart as they are ID's that refer to a database so for example I want:
for (each element in the cart){ get the image associated with the id get the name associated with the id add a delete from cart for each id }
Could someone tell me a way of being able to work with each cart element in turn. I'm OK with the get image/get name/delete from cart aspects but have no idea how to loop through a session variable in php.
Thank you
