The default WooCommerce checkout does not fit every business. In this tutorial, I will show you how to add custom fields, rearrange the layout, and customize the checkout experience without plugins.
Adding a Custom Checkout Field
Use the woocommerce_checkout_fields filter to add your field to the billing, shipping, or order section. Define the field type, label, placeholder, required status, and priority to control its position.
Saving Custom Field Data
Hook into woocommerce_checkout_process to validate your field and woocommerce_checkout_update_order_meta to save the value to the order. Use woocommerce_order_details_after_order_table to display it in the order confirmation.
Removing Unwanted Fields
To remove fields like Company Name or Address Line 2, use the same woocommerce_checkout_fields filter and unset the fields you do not need. This simplifies the form and can improve conversion rates.
Showing Fields in the Admin
Add your custom field to the order admin page using woocommerce_admin_order_data_after_billing_address. This lets your team see custom field values when processing orders.
