Using this we can create Shopping cart features in an application.
CI Provide cart library to implement this functionality.
Step to Implement Card Functionality:-
1) Create Controller
2 ) Load cart library under Controller Constructor
$this->load->library('cart')
3) Create Controller Index method and Add Multiple Items into cart
4) Create View and show cart content
Complete Code of Cart:-
<?php
class Shoppingcart extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->library('cart');
}
function index()
{
$this->cart->destroy();
$data = array(
array(
'id' => 'sku_123ABC',
'qty' => 1,
'price' => 100,
'name' => 'T-Shirt',
'options' => array('Size' => 'L', 'Color' => 'Red')
),
array(
'id' => 'sku_567ZYX',
'qty' => 1,
'price' => 1200,
'name' => 'Shoes'
),
array(
'id' => 'sku_965QRS',
'qty' => 1,
'price' => 2000,
'name' => 'Watch'
));
$this->cart->insert($data);
$this->load->view('cartview');
}
function updatecart()
{
$data = array(
array(
'rowid' => '0256a32c98ce49afbe2a4eb8c96c5884',
'qty' => $this->input->post('txt1')
),
array(
'rowid' => '90972f7cfcd380a9fa7821d30a9b2fb2',
'qty' => $this->input->post('txt2')
),
array(
'rowid' => '46acd2fb2e0d0b4a29c67e7ddf1c8946',
'qty' => $this->input->post('txt3')
)
);
$this->cart->update($data);
$this->load->view('cartview');
}
}
?>
Cartview:-
