Cash on Delivery Fee (Block Checkout Compatible)

By default, WooCommerce uses the classic editor for products. This snippet forces WordPress to use the block editor for the product post type, allowing you to build product pages with modern Gutenberg blocks, patterns, and Full Site Editing–compatible layouts.

What it does

• Adds +500 Ft COD fee (gross) at checkout
• Applies only if:
  • payment method is cod or cheque
  • shipping method is not local_pickup
• Works with Block Checkout (Store API)
• Ensures the fee is stored on the order, so it shows in:
  • confirmation emails
  • WooCommerce order view
  • PDFs / integrations that read order totals

Why it’s needed

Block Checkout can calculate fees in the cart UI, but without syncing, some fees may not persist into the final order. This snippet forces the fee calculation and copies the fees from the cart into the order during Store API checkout.
