1. Overview

This document explains how to modify payment methods at checkout based on product type in WooCommerce. Specifically:

• If the cart contains downloadable products, only online payment methods (e.g., PayPal, Stripe) will be displayed, and Cash on Delivery (COD) will be hidden.
• If the cart contains only non-downloadable products, only COD will be displayed, and other payment methods will be hidden.

This solution uses custom PHP code snippets that hook into WooCommerce’s payment gateway system.
