    <div class="card-body">
        <h5 class="card-title">Canon EOS 1500D</h5>
        <p class="card-text">Lorem ipsum dolor sit amet, consectetur
            adipiscing exercitationem elit.</p>

                        class="align-middle glyphicon glyphicon-star-empty"
                        aria-hidden="true"></span>
                </div>
                <div class="col-md-6">
                    <button type="button"
                        class="btn btn-primary btn-sm btn-block"

                            aria-hidden="true"></span> ADD TO CART

                </div>
            </div>
        </div>
    </div>
</div>
   

Card with add-to-cart handle

The above HTML includes an interactive add-to-cart button in the product tile. On clicking this button, the UI will acknowledge users that the product is added to the cart. Also, it disables the clicked button to prevent multiple submits to the cart.

The below JavaScript simply do this at the UI level to notify the end-users. This is the place where we can embed AJAX to add items to the cart session.

assets/js/card.js


function addToCart(id) {
	var addToCartButton = document.getElementById("addToCart-" + id);
	document.getElementById("addToCart-" + id).innerHTML = "";
	document.getElementById("addToCart-" + id).innerHTML = "Added";
	document.getElementById("addToCart-" + id).disabled = true;
}
   

Load cards with dynamic products using PHP MySQL

This section mostly has the dynamic part of this shopping cart example. It includes the .sql, Model and PHP snippets used to load products into the Bootstrap cards UI.

Database script

Import this script into a database to display dynamic products. Configure the database details on lib/DataSource.php before running this shopping cart example.

It contains the data dump with the product title, price, images and etc.


--
-- Table structure for table `tbl_product`
--

CREATE TABLE `tbl_product` (
  `id` int(11) NOT NULL,
  `title` varchar(255) NOT NULL,
  `description` varchar(255) NOT NULL,
  `currency_symbol` varchar(25) NOT NULL,
  `price` decimal(10,2) NOT NULL,
  `image_path` varchar(255) NOT NULL,
  `rating` double NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

--
-- Dumping data for table `tbl_product`
--

INSERT INTO `tbl_product` (`id`, `title`, `description`, `currency_symbol`, `price`, `image_path`, `rating`) VALUES
(1, 'Canon EOS 1500D 24.1', 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.', '$', '99.00', './data/camera.jpg', 5),
(2, 'iPhone 12 Pro Max', 'Duis aute irure dolor in reprehenderit fugiat nulla pariatur.', '$', '159.00', './data/mobile.jpg', 4),
(3, 'MLA22HN/A Wireless Keyboard', 'Sed do eiusmod tempor incididunt et dolore magna aliqua.', '$', '79.00', './data/keyboard.jpg', 4),
(4, '21.5‑inch iMac', 'Sunt in culpa qui officia deserunt mollit anim id est laborum.', '$', '199.00', './data/computer.jpg', 3),
(5, 'Pro Audio X240', 'Excepteur sint occaecat perspiciatis unde cupidatat non proident.', '$', '19.00', './data/headset.jpg', 2),
(6, 'Micro USB 55', 'Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet.', '$', '9.00', './data/usb-cable.jpg', 3);


PHP script to fetch products

This PHP code imports the required model and fetches dynamic products into an array.  A PHP foreach loop iterates the array to display products in Bootstrap cards.

index.php


<?php
require_once __DIR__ . '/lib/Product.php';
$productModel = new Product();
$productResult = $productModel->getAllProduct();
?>
<?php
if (! empty($productResult)) {
    $productArray = array_chunk($productResult, 3);
    $i = 1;
    foreach ($productArray as $column) {
        ?>
<div class="row mb-5">
        <?php
        foreach ($column as $k => $v) {
            ?>
            <!--  Display product tile in a Bootstrap card -->
            <?php
        }
        ?>
        </div>
<?php
        $i ++;
    }
}
?>
   

PHP 5 Star rating with filled stars

The PHP loop displays a dynamic 5-star rating in the Bootstrap card footer. The start rating count is saved in the product database.


<?php
for ($a = 1; $a <= 5; $a ++) {
    $ratingClass = "glyphicon-star-empty";
    if ($column[$k]["rating"] >= $a) {
        $ratingClass = "glyphicon-star";
    }
    ?>
<span class="align-middle glyphicon <?php echo $ratingClass;?>"
	aria-hidden="true"></span>
<?php
}
?>

Application library files to query the database

The Product model connects the database at the time of instantiation. It sets the connection object in its constructor.

The collection object has visibility across the class. The getAllProduct() function prepares a straightforward query to fetch the products.

lib/Product.php


<?php
use Phppot\DataSource;

class Product
{

    private $ds;

    function __construct()
    {
        require_once __DIR__ . '/DataSource.php';
        $this->ds = new DataSource();
    }

    function getAllProduct()
    {
        $sql = "SELECT * FROM tbl_product";
        $result = $this->ds->select($sql);
        return $result;
    }
}
