# CodeIgniter4-Cart-Module
A basic port of the CodeIgniter 3 cart module for CodeIgniter 4. With the 
CodeIgniter 3 Cart module being officially dropped, I wanted to implement 
it in CodeIgniter 4. This is a small example of that. This is not truly 
'supported' since I just kinda threw it together on a whim for a project 
that arose, but feel free to contact me regarding it or offer PR's for 
any improvements and/or corrections to the existing codebase.

## Installation:
 - Install via composer `composer install jason-napolitano/codeigniter4-cart-module` 
## Usage
 - More detailed information can be found [here](https://codeigniter.com/userguide3/libraries/cart.html)
 ```php
 // Call the cart service using the helper function
 $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
$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();
```
