Adding item to cart and view them to see total etc

Hi Swain

I see and dont have to use any jquery simply php, make sense. which means let me work on this if i get stuck to display the items on the table will shout.

Sure, I can provide you with an example of how to add items to a shopping cart and view them in PHP. Here's a simple example:

First, you will need to create a session to store the cart items. You can do this by calling the `session_start()` function at the beginning of your script:

session_start();

Next, you can create a function to add items to the cart. In this example, we'll use an associative array to store the product ID, name, price, and quantity for each item:

function add_to_cart($product_id, $product_name, $product_price, $quantity) {
    // Check if the product already exists in the cart
    if (isset($_SESSION['cart'][$product_id])) {
        // Increment the quantity of the existing item
        $_SESSION['cart'][$product_id]['quantity'] += $quantity;
    } else {
        // Add a new item to the cart
        $_SESSION['cart'][$product_id] = array(
            'name' => $product_name,
            'price' => $product_price,
            'quantity' => $quantity
        );
    }
}

To add an item to the cart, you can call this function with the product ID, name, price, and quantity:

add_to_cart(1, 'Product A', 10.00, 2);

To view the items in the cart, you can loop through the `$_SESSION['cart']` array and display the product name, price, and quantity for each item:

if (!empty($_SESSION['cart'])) {
    echo '

';
    echo '';
    $total = 0;
    foreach ($_SESSION['cart'] as $product_id => $item) {
        $product_name = $item['name'];
        $product_price = $item['price'];
        $quantity = $item['quantity'];
        $item_total = $product_price * $quantity;
        $total += $item_total;
        echo '';
    }
    echo '';
    echo '

Product Name	Price	Quantity	Total
' . $product_name . '	' . $product_price . '	' . $quantity . '	' . $item_total . '
Total			' . $total . '

';
} else {
    echo 'Your cart is empty.';
}

This will display a table of the items in the cart, along with their prices, quantities, and totals. Finally, you can add a "checkout" button that will take the user to a checkout page:

html

   

In the checkout page, you can process the order and clear the cart by calling the `session_unset()` function:

session_unset();

I hope this helps you get started with adding items to a shopping cart and viewing them in PHP!
