If the product already exists in the cart, the script increments the existing quantity by the value of Validation: Professional implementations include validation to ensure
// CSRF check if (!hash_equals($_SESSION['csrf_token'], $_POST['csrf_token'] ?? '')) die('Invalid request');
At its core, the add-cart.php file accepts two critical pieces of information:
: Before adding an item, the script checks if the product_id is already in the cart.
The e-commerce landscape relies heavily on simple, fast interactions to convert visitors into buyers. Behind the scenes, many custom-built or legacy online stores handle shopping cart actions using explicit PHP scripts, often named add-cart.php .
If the URL looks like add-cart.php?id=101&price=50 , an attacker might change the price to 0.01 . However, modern applications usually calculate price based on the database ID server-side. The num parameter remains the more persistent threat because applications expect the user to define how many items they want.

add-cart.php is a typical server-side script responsible for receiving product data and updating the user's session or database to include that item.
While the core security principles are universal, applying them differs by platform.
If you are managing or refactoring an application that utilizes explicit file endpoints like add-cart.php , consider implementing these structural improvements:
