Make state checkout field required for a Vietnam country in WooCommerce

Question

The country of Vietnam in WooCommerce does not have defined states, so I added some states to my checkout page.

This is my code:

add_filter( \'woocommerce_         


        

Answer 1

The following function will make for Vietnam the state field as a required in woocommerce:

add_filter( 'woocommerce_get_country_locale', 'custom_country_locale', 10, 1 );
function custom_default_address_fields( $locale ) {
    $locale['VN']['state']['required'] = true;

    return $locale;
}

Code goes in functions.php file of your active child theme (active theme). Tested and works.

Explanations: Each country have specific "locale" fields settings in WooCommerce. We are adding/altering the default WooCommerce country locale settings that are defined on WC_Countries get_country_locale() method
