Are you looking to create a robust and efficient e-commerce platform using PHP? Look no further! In this post, we'll explore how to implement a basic shopping system using PHP, focusing on a simple ID-based system. php id 1 shopping
$query = "SELECT price FROM products WHERE id = '$product_id'"; $result = mysqli_query($conn, $query); $row = mysqli_fetch_assoc($result); // Check if cart exists if (isset($_SESSION["cart"])) {
// Connect to database $conn = mysqli_connect("localhost", "username", "password", "database"); $query = "SELECT price FROM products WHERE id
// Display product with ID 1 $query = "SELECT * FROM products WHERE id = 1"; $result = mysqli_query($conn, $query); $row = mysqli_fetch_assoc($result);
