WooCommerce - 覆盖现有结帐字段上的计费状态和邮政编码 - WooCommerce - Overriding billing state and post code on existing checkout fields

我找不到 ovveride 计费状态和邮政编码的方法。

如何编辑现有帐单字段的其他部分，如帐单状态和邮政编码？

这是我在子主题的functions.php文件中的内容（我已经包含了影响计费部分的代码）：

    <?php
function my_custom_checkout_field( $checkout ) {
  global $wpdb;
  $check_zone  = $wpdb->get_results("select area_name from brick_area where id='".$_SESSION['area']."'",ARRAY_A);
                if(!empty($check_zone)){
                    $check_zoneid = $check_zone['0'];
                }

    woocommerce_form_field( 'my_field_name', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Delivery Area'),
        'placeholder'   => __('Area'),
        'readonly'      =>'readonly',
        'default'       => $check_zoneid['area_name']
        ), $checkout->get_value( 'my_field_name' ));

    woocommerce_form_field( 'my_expected_date', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'required'      => true,
        'label'         => __('Expected Delivery Date'),
        'placeholder'   => __('Enter expected delivery date.'),
        ), $checkout->get_value( 'my_expected_date' ));
   /*woocommerce_form_field( 'my_expected_time', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'required'      => true,
        'label'         => __('Expected Delivery Time'),
        'placeholder'   => __('Enter expected delivery time.'),
        ), $checkout->get_value( 'my_expected_time' ));*/
    woocommerce_form_field( 'site_contact_name', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'required'      => true,
        'label'         => __('Site Contact Person Name'),
        'placeholder'   => __('Enter site contact person name.'),
        ), $checkout->get_value( 'site_contact_name' ));    
    woocommerce_form_field( 'site_contact_phone', array(
        'type'          => 'tel',
        'class'         => array('my-field-class form-row-wide'),
        'required'      => true,
        'label'         => __('Site Contact Phone Number'),
        'placeholder'   => __('Enter site contact phone number.'),
        ), $checkout->get_value( 'site_contact_phone' ));       
}
        $fields['billing']['billing_city']['default'] = $_SESSION['cn'];
        add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );
        function custom_override_default_address_fields( $address_fields ) {
            // we are changing here billing_state field to required
            $fields['billing']['billing_state']['required'] = true;
            return $address_fields;
        }
        /*$fields['billing']['my_field_name']['default'] = $check_zoneid['area_name'];
        $fields['billing']['my_field_name']['label'] = 'Area';*/
        return $fields;
        }
 ?>

谢谢

这是覆盖计费状态和计费发布代码的完整方法，使计费选择器具有选项。

以下是功能齐全且经过测试的代码：

取消设置帐单状态和邮政编码结帐字段

add_filter( 'woocommerce_checkout_fields' , 'partial_unsetting_checkout_fields' );
function partial_unsetting_checkout_fields( $fields ) {
     unset($fields['billing']['billing_state']);
     unset($fields['billing']['billing_postcode']);
     return $fields;
}

重新插入自定义帐单状态和邮政编码结帐字段

add_filter( 'woocommerce_default_address_fields' , 'art_override_default_address_fields' );
function art_override_default_address_fields( $address_fields ) {
  // @ for state
    $address_fields['billing_state']['type'] = 'select';
    $address_fields['billing_state']['class'] = array('form-row-wide');
    $address_fields['billing_state']['required'] = true;
    $address_fields['billing_state']['label'] = __('State', 'my_theme_slug');
    $address_fields['billing_state']['placeholder'] = __('Enter state', 'my_theme_slug');
    $address_fields['billing_state']['default'] ='Choice 1';
    $address_fields['billing_state']['options'] = array(
        'option_1' => 'Choice 1',
        'option_2' => 'Choice 2',
        'option_3' => 'Choice 3'
    );
    // @ for postcode
    $address_fields['billing_postcode']['type'] = 'text';
    $address_fields['billing_postcode']['class'] = array('form-row-wide');
    $address_fields['billing_postcode']['required'] = true;
    $address_fields['billing_postcode']['label'] = __('Postcode', 'my_theme_slug');
    $address_fields['billing_postcode']['placeholder'] = __('Enter your postcode', 'my_theme_slug');

    return $address_fields;
}

自然，这将继续功能.php您的活动子主题或主题的文件

官方参考：WooThemes - 使用操作和过滤器自定义结帐字段

关于'class'财产的说明
有两种方法可以处理它：
该字段单独在一行中（宽度 100%），您使用： 'form-row-wide'
同一行上有 2 个并排字段，您使用：
第一个字段的'form-row-first'
第二个字段的'form-row-last'

//-------------------------- OVERRIDING BILLING STATE FIELD -------------------------------//
//Removing previous one by using unset
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
// Our hooked in function - $fields is passed via the filter!
function custom_override_checkout_fields( $fields ) {
     unset($fields['billing']['billing_state']);
     return $fields;
}
        
add_filter( 'woocommerce_default_address_fields' , 'art_override_default_address_fields' );
function art_override_default_address_fields( $address_fields ) {
    // @ for state
    $address_fields['Billing_State']['type'] = 'text';
    $address_fields['Billing_State']['class'] = array('form-row-wide');
    $address_fields['Billing_State']['required'] = true;
    $address_fields['Billing_State']['label'] = __('State', 'my_theme_slug');
    $address_fields['Billing_State']['placeholder'] = __('Enter state', 'my_theme_slug');
    return $address_fields;
}
