It receives data—such as a product's unique ID—and manages it within a PHP session to track the items as the user continues to browse. Key Components for High-Quality Implementation
Before writing a single line of code, we must define the metrics of quality.
if ($_SERVER['REQUEST_METHOD'] === 'POST') addcartphp num high quality
CREATE TABLE cart_items ( id INT AUTO_INCREMENT PRIMARY KEY, user_id INT NOT NULL, product_id INT NOT NULL, quantity INT NOT NULL CHECK (quantity > 0), added_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, UNIQUE KEY (user_id, product_id) );

$subtotal = $product['price'] * $qty; $total += $subtotal; $cart_items[] = [ 'product' => $product, 'quantity' => $qty, 'subtotal' => $subtotal ];
