<h1>Multicart for codeigniter</h1>

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.

<h2>Installation</h2>

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

<h1>Example Usage MultiCart</h1> <h2>Create instances</h2> ```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 ``` <h3>Insert a product</h3> ```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);

<h3>Remove a product by rowid</h3> <p>You just need to pass a rowid that there</p> ```php $this->shop1->remove_item("d81d234f1250c815641edb236f705ed5"); ``` <h3>Get cart content</h3> ```php $this->shop1->get_content(); ``` <h3>Get total cost</h3> ```php $this->shop1->total_cart(); ``` <h3>Get total items</h3> ```php $this->shop1->total_articles(); ``` <h3>Destroy shop1 instance cart</h3> ```php $this->shop1->destroy(); ``` <h1>Complete example usage</h1> ```php class Multi extends CI_Controller { //load library and create new instances public function __construct() { parent::__construct(); $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 }
