Mastering the WooCommerce Default Address Fields Filter: A Comprehensive Guide
As a WordPress developer, you may have encountered the need to customize the default address fields in your WooCommerce-powered e-commerce store. The woocommerce_default_address_fields
filter is a powerful tool that allows you to modify these fields, but it can be a bit tricky to navigate. In this comprehensive guide, we'll explore the ins and outs of this filter, providing you with the knowledge and practical examples you need to master its use and enhance your online store.
Understanding the woocommerce_default_address_fields Filter
The woocommerce_default_address_fields
filter is a WooCommerce-specific hook that allows you to modify the default address fields displayed on the checkout page, as well as in the customer's account area. These fields include:
- Country
- First Name
- Last Name
- Company
- Address 1
- Address 2
- City
- State
- Postcode
By using this filter, you can customize the appearance, validation, and behavior of these fields to better suit the needs of your customers and your business.
Real-World Examples: Customizing Default Address Fields
Let's dive into some real-world examples to illustrate how you can leverage the woocommerce_default_address_fields
filter to enhance your WooCommerce store.
Example 1: Removing the Company Field
Suppose you don't require your customers to provide a company name during checkout. You can remove the company field by modifying the woocommerce_default_address_fields
filter like this:
add_filter( 'woocommerce_default_address_fields', 'remove_company_field' );
function remove_company_field( $fields ) {
unset( $fields['company'] );
return $fields;
}
In this example, the remove_company_field
function removes the company
field from the default address fields array.
Example 2: Making the State Field Required
Sometimes, you may need to make certain address fields required, such as the state field. You can achieve this by modifying the woocommerce_default_address_fields
filter:
add_filter( 'woocommerce_default_address_fields', 'make_state_field_required' );
function make_state_field_required( $fields ) {
$fields['state']['required'] = true;
return $fields;
}
In this example, the make_state_field_required
function sets the required
parameter of the state
field to true
, making it a mandatory field during checkout.
Example 3: Changing the Label of the Address 1 Field
You may want to customize the label of a specific address field, such as the "Address 1" field. You can do this by modifying the woocommerce_default_address_fields
filter:
add_filter( 'woocommerce_default_address_fields', 'change_address_1_label' );
function change_address_1_label( $fields ) {
$fields['address_1']['label'] = __( 'Street Address', 'your-text-domain' );
return $fields;
}
In this example, the change_address_1_label
function changes the label of the address_1
field to "Street Address".

Example 4: Adding a New Address Field
If you need to add a custom address field, you can do so by modifying the woocommerce_default_address_fields
filter:
add_filter( 'woocommerce_default_address_fields', 'add_custom_address_field' );
function add_custom_address_field( $fields ) {
$fields['apartment_number'] = array(
'label' => __( 'Apartment Number', 'your-text-domain' ),
'required' => false,
'class' => array( 'form-row-wide' ),
'priority' => 70,
);
return $fields;
}
In this example, the add_custom_address_field
function adds a new apartment_number
field to the default address fields array. You can customize the field's label, required status, CSS class, and priority (the order in which it's displayed).
Example 5: Validating Address Fields
You can also use the woocommerce_default_address_fields
filter to add custom validation rules to your address fields. For instance, you might want to ensure that the postcode field only accepts a specific format:
add_filter( 'woocommerce_default_address_fields', 'validate_postcode_field' );
function validate_postcode_field( $fields ) {
$fields['postcode']['validate'] = array( 'postcode' );
return $fields;
}
In this example, the validate_postcode_field
function adds a "postcode" validation rule to the postcode
field, ensuring that the entered value matches the expected format.
Understanding the Filter's Structure
The woocommerce_default_address_fields
filter passes an associative array of default address fields, where the keys represent the field names, and the values are arrays containing field properties such as label
, required
, class
, and priority
.
Here's an example of the default structure of the $fields
array:
$fields = array(
'country' => array(
'label' => __( 'Country', 'woocommerce' ),
'required' => true,
'class' => array( 'form-row-wide', 'address-field', 'update_totals_on_change' ),
'autocomplete' => 'country',
'priority' => 10,
),
'first_name' => array(
'label' => __( 'First name', 'woocommerce' ),
'required' => true,
'class' => array( 'form-row-first', 'address-field' ),
'autocomplete' => 'given-name',
'priority' => 10,
),
// Additional fields...
);
By understanding the structure of this array, you can easily modify the existing fields or add new ones to suit your specific requirements.
