README

This model is a simple ZF2 Shopping Cart solution. Provide basic functionality to create and modify Shopping Cart with any content in it. Easy to extend, just create your own Cart Entity and push it during Cart initialisation.

Inspired by

I was inspired to create the ShoppingCart by great job of Vincenzo Provenza and Concetto Vecchio (http://github.com/vikey89/ZendCart). Keeped the same idea behind but made it more flexible, easier to extend and simplier to change.

Zend Framework 3

This module was forked and repaired for zf3

Installation

For the installation uses composer composer. Add this project in your composer.json:

"require": {
    "simpavl/zf3-shoppingcart": "dev-master"
}

Post Installation

Configuration:

• Add the module of config/application.config.php under the array modules, insert ShoppingCart.
• Copy a file named shoppingcart.global.php.dist to config/autoload/ and change name to shoppingcart.global.php.
• Modify config to fit your expectations.

Examples

Insert

You can insert as many items to the cart as you want. Each entry in cart will have unique token to work with. Example with one product:

$product = array(
    'id'      => 'XYZ',
    'qty'     => 1,
    'price'   => 15.15,
    'product' => 'Book: ZF2 for beginners',
);
$this->ShoppingCart()->insert($product);

Example with 2 products:

$products = array(
    array(
        'id'      => 'XYZ',
        'qty'     => 1,
        'price'   => 15.15,
        'product' => 'Book: ZF2 for beginners',
    ),
    array(
        'id'      => 'ZYX',
        'qty'     => 3,
        'price'   => 19.99,
        'product' => 'Book: ZF2 for advanced users',
    )
);
$this->ShoppingCart()->insert($products);

Remove

$token => '4b848870240fd2e976ee59831b34314f7cfbb05b';
$this->ShoppingCart()->remove($token);

Destroy

Erase Shopping Cart completely.

$this->ShoppingCart()->destroy();

Cart

Get all content of Cart.

$this->ShoppingCart()->cart();

Total Sum

$this->ShoppingCart()->total_sum();

Total Items

$this->ShoppingCart()->total_items();

Example in controller

return new ViewModel(array(
    'cart' => $this->ShoppingCart()->cart(),
    'total_items' => $this->ShoppingCart()->total_items(),
    'total_sum' => $this->ShoppingCart()->total_sum(),
));

How to change/extend Shopping Cart

Provided Shopping Cart Entity is really basic one. You can change the structure of it. For example, if you need to add options to each item in the cart or to provide discount field and so on. What you should do:

• copy ShoppingCart/Entity/ShoppingCartEntity to your module
• modify YourModule/Entity/ShoppingCartEntity: add any fields you need to have
• during Shopping Cart initialisation provide your YourModule/Entity/ShoppingCartEntity

$this->ShoppingCart()->setEntityPrototype(new YourModule/Entity/ShoppingCartEntity());
