Multicart for codeigniter

This library needs to use the php native sessions, including My_Session.php file in the folder and they are extended libraries correctly. Using sessions remains exactly the same as with native codeigniter.

Installation

Download files hosted on libraries folder and place them in the libraries folder of your project.

Example Usage MultiCart

Create instances

```php $this->load->library("udp_cart");//load library $this->shop1 = new Udp_cart("shop1");//cart1 $this->shop2 = new Udp_cart("shop2");//cart2 $this->shop3 = new Udp_cart("shop3");//cart3 ```

Insert a product

```php $article = array("id" => rand(1,10),"qty" => mt_rand(1,10),"name" => "shoes","price" => "10"); $article["options"] = array("color" => "black", "size" => "4");

$this->shop1->insert($article);

<h3>Update product with options and id 7</h3>
```php
$article = array("id" => 7, "qty" => 1, "name" => "shoes", "price" => 2);
$article["options"] = array("color" => "black", "size" => "4");
$this->shop1->update($article);

```php $this->shop1->remove_item("d81d234f1250c815641edb236f705ed5"); ```
