CodeIgniter4-Cart-Module

This is a composer installable, CodeIgniter 4 module that is nearly a direct port of the Codeigniter 3 Cart Library Class. Of course, this has been mildly updated and is consistent with the new version of the framework.

This means that instead of just being a class that you can use in your projects, this library has been updated with Namespaces, has been refactored to adhere to the CodeIgniter style guide and also has been built to use CodeIgniter 4's Service Container to allow for a shared Cart instance across your application.

More detailed documentation can be found here. Please note that the documentation is for the CodeIgniter 3 library but the fundamentals and inner workings of the library are still identical. The most notable changes are how you use it (read below) and to return the total items in your cart, you now call $cart->totalItems() instead of $this->cart->total_items().

Please take note that there are no tests for this package since it is just a port from an existing Codeigniter library and works just the same.

Installation:

• Install via composer composer install jason-napolitano/codeigniter4-cart-module
• Add it to the $psr4 array in app/Config/Autoload.php:

$psr4 = [
   'CodeIgniterCart' => ROOTPATH . 'vendor/jason-napolitano/codeigniter4-cart-module/src'

   // OTHER PSR4 ENTRIES
];

Usage

// Call the cart service
$cart = \Config\Services::cart();

// Insert an array of values
$cart->insert(array(
   'id'      => 'sku_1234ABCD',
   'qty'     => 1,
   'price'   => '19.56',
   'name'    => 'T-Shirt',
   'options' => array('Size' => 'L', 'Color' => 'Red')
));

// Update an array of values
$cart->update(array(
   'rowid'   => '4166b0e7fc8446e81e16883e9a812db8',
   'id'      => 'sku_1234ABCD',
   'qty'     => 3,
   'price'   => '24.89',
   'name'    => 'T-Shirt',
   'options' => array('Size' => 'L', 'Color' => 'Red')
));

// Get the total items. Formerly known as total_items()
$cart->totalItems();

// Remove an item using its `rowid`
$cart->remove('4166b0e7fc8446e81e16883e9a812db8');
  
// Clear the shopping cart
$cart->destroy();

// Get the cart contents as an array
$cart->contents();
