Here, we will guide you on “How you can Customize Checkout Fields using actions and filters.
Before Diving into woo-commerce customizing fields, it’s essential to understand Actions and Filters in WooCommerce.

  • Actions allow you to execute custom code at specific points in the checkout process and perform actions such as sending emails, updating the database, or redirecting the user to a particular page.
  • Filters allow you to modify the behavior of WooCommerce without changing the core code; Filter makes it easy to customize the checkout process without any problem.

  • First name
  • Last name
  • Company name
  • Country
  • Address line 1
  • Address line 2
  • Town/City
  • Province/County/District
  • Postcode / ZIP
  • Phone
  • Email address

We will modify some checkout fields to show you how you can also customize Checkout fields by using actions and filters.
