It’s possible to fully customize the registration form on the “My Account” page starting in WooCommerce 2.1.

To begin you must enable the registration:

By default the form is displayed as follows:

Adding new fields

Appears quite modest and without many fields, but we can add additional fields using the actions:

• woocommerce_register_form_start – Appears before the “Address Email” field
• woocommerce_register_form – Appears after the “Password” field

For example, let’s add “First name”, “Last name”, and “Phone number” fields:

Note that we use fields as billing_* to be able to associate with the fields customer’s account on WooCommerce later.

Here is the list of all the fields that we can use:

• billing_first_name
• billing_last_name
• billing_company
• billing_address_1
• billing_address_2
• billing_city
• billing_postcode
• billing_country
• billing_state
• billing_email
• billing_phone

Validating the custom fields

It’s very important to validate the fields and make sure that the user is filling them. To do this we will use the woocommerce_register_post action.

We should save that custom fields in user profile and for do this we’ll use the woocommerce_created_customer action:

And voila! All the fields saved and working perfectly 🙂
