Making woocommerce checkout form state field not r

问题:

I have a WordPress+Woo-commerce site and I want to make the state field on the checkout form optional based on the selected country. For example I want my customers to add state field only if they belong to one of U.S.A. states.

How do I do this?

回答1:

add_filter( 'woocommerce_default_address_fields' , 'custom_override_state_required' );
function custom_override_state_required( $address_fields ) {
  $wc = WC();
  $country = $wc->customer->get_country();
  if($country !== 'US'){
     $address_fields['state']['required'] = false;
  }
  return $address_fields;
}

This is code that worked for me. I am posting this answer without editing @zipkundan answer because I don't see any mistakes in his answer but somehow it was not working for me. That may be because of WooCommerce version or may have another reason!! I recommend to try both answers if someone have similar requirements.

In case someone stumbles on this, Woocommerce changed the name of the state fields. Below is the updated solution:

add_filter( 'woocommerce_checkout_fields','custom_override_default_address_fields' );

function custom_override_default_address_fields($fields){
    global $woocommerce;
    $country = $woocommerce->customer->get_country();

    if($country !== 'US'){
        $fields['billing']['billing_state']['required'] = false;
        $fields['shipping']['shipping_state']['required'] = false;
    }

    return $fields;
}

Try this (in your functions.php)

add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );
function custom_override_default_address_fields( $address_fields ) {
     global $woocommerce;
     $country = $woocommerce->customer->get_country();
     if($country !== 'US'){
        $address_fields['state']['required'] = false;
     }
     return $address_fields;
}

This will make the 'state' field optional when the visitor is not from USA.
Hope this helps.

UPDATE

add_filter( 'woocommerce_checkout_fields', 'custom_override_default_address_fields' );
function custom_override_default_address_fields($fields){
    global $woocommerce;
    $country = $woocommerce->customer->get_country();
    if($country !== 'US'){
        $fields['billing']['state']['required'] = false;
        $fields['shipping']['state']['required'] = false;
    }
    return $fields;
}

I had trouble getting the other answers to work until I realized there's also the woocommerce_get_country_locale hook from WC_Countries. Which sets state required based on the chosen country through javascript in the frontend.

add_filter('woocommerce_get_country_locale', 'update_country_locales', 10 , 1);

function update_country_locales($countries) {

    foreach ($countries as $country => $fields) {
        if (isset($fields['state']) && $country != 'US') {
            $countries[$country]['state']['required'] = false;
        }
    }

    return $countries;
}
