There are two filters to manage checkout fields. You can use woocommerce_checkout_fields
filter to make field "not-required", but the red asterisk will not be removed.
When dealing with default address fields with woocommerce_checkout_fields
filter, some of your changes will not take effect, because woocommerce_default_address_fields
filter and its default values may override your changes.
Only partly functional code:
function custom_override_checkout_fields( $fields ) {
$fields['billing']['billing_address_1']['required'] = false ;
return $fields;
}
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
Address field (#1) is not required anymore, but still has red asterisk.
Fully functional code:
function custom_override_default_address_fields( $address_fields ) {
$address_fields['address_1'][ 'required' ] = false;
return $address_fields;
}
add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );
Now this field is not required, and red asterisk is gone.
Documentation says that "In some specific cases you will need to use the woocommerce_default_address_fields filter. This filter is applied to all billing and shipping default fields."
