These items can be retrieved and displayed in a standard “shopping cart” format, allowing the user to update the quantity or remove items from the cart.In this tutorial you will learn how to create shopping cart with CodeIgniter, Ajax and MySQL.You can also download source code of live to build your codeIgniter shopping cart from scratch.
Step 1: Create MySQL Database and Table
The following SQL creates a product table in the MySQL database.
The following SQL creates a product_description table in the MySQL database.
The following SQL creates a product_image table in the MySQL database.
The following SQL creates a orders table in the MySQL database.
The following SQL creates a orders_product table in the MySQL database.
The following SQL creates a customer table in the MySQL database.
Step 2: Create a model file
Create a model file named "Product_model.php" inside "application/models" folder.
Step 3: Create a controller file
Next create a controller file named "Product.php" inside "application/controllers" folder.
Step 4: Create a controller file
Next create a controller file named "Cart.php" inside "application/controllers" folder.

Step 1: Create MySQL Database and Table
The following SQL creates a product table in the MySQL database.
CREATE TABLE `product` (
`product_id` int(11) NOT NULL,
`model` varchar(64) NOT NULL,
`sku` varchar(64) NOT NULL,
`quantity` int(4) NOT NULL DEFAULT '0',

`status` tinyint(1) NOT NULL DEFAULT '0',
`date_added` varchar(12) NOT NULL,
`date_modified` varchar(12) NOT NULL

ALTER TABLE `product`
ADD PRIMARY KEY (`product_id`);
ALTER TABLE `product`
MODIFY `product_id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;
?>
The following SQL creates a product_description table in the MySQL database.
CREATE TABLE `product_description` (
`product_id` int(11) NOT NULL,
`language_id` int(11) NOT NULL,
`slug` varchar(255) DEFAULT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `product_description`
ADD PRIMARY KEY (`product_id`,`language_id`),
ADD KEY `name` (`name`);

The following SQL creates a product_image table in the MySQL database.
CREATE TABLE `product_image` (
`id` int(11) NOT NULL,
`product_id` int(11) NOT NULL,
`image` varchar(255) NOT NULL

ALTER TABLE `product_image`
ADD PRIMARY KEY (`id`);
ALTER TABLE `product_image`
MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

The following SQL creates a orders table in the MySQL database.
CREATE TABLE `orders` (
`order_id` int(11) NOT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `orders`
ADD PRIMARY KEY (`order_id`);
ALTER TABLE `orders`
MODIFY `order_id` int(11) NOT NULL AUTO_INCREMENT;
?>
The following SQL creates a orders_product table in the MySQL database.
CREATE TABLE `orders_product` (
`order_product_id` int(11) NOT NULL,
`order_id` int(11) NOT NULL,
`product_id` int(11) NOT NULL,
`name` varchar(255) NOT NULL,

`quantity` int(4) NOT NULL,
`price` decimal(15,4) NOT NULL DEFAULT '0.0000',
`total` decimal(15,4) NOT NULL DEFAULT '0.0000'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `orders_product`
ADD PRIMARY KEY (`order_product_id`),
ADD KEY `order_id` (`order_id`);
ALTER TABLE `orders_product`
MODIFY `order_product_id` int(11) NOT NULL AUTO_INCREMENT;
?>
The following SQL creates a customer table in the MySQL database.
CREATE TABLE `customer` (
`customer_id` int(11) NOT NULL,
`firstname` varchar(32) NOT NULL,
`lastname` varchar(32) NOT NULL,
`email` varchar(96) NOT NULL,
`phone` varchar(32) NOT NULL,
`password` varchar(40) DEFAULT NULL,
`salt` varchar(9) DEFAULT NULL,
`status` tinyint(1) NOT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `customer`
ADD PRIMARY KEY (`customer_id`);
ALTER TABLE `customer`
MODIFY `customer_id` int(11) NOT NULL AUTO_INCREMENT;
?>
Step 2: Create a model file
Create a model file named "Product_model.php" inside "application/models" folder.
