PROSAGA码农传奇-Xedge-Woocommerce 3中的可编辑管理员自定义帐单字段错误问题

<div class =“post-text”itemprop =“text”>
  
    问题是
     <code>
 $theorder
 </code>
     没有定义，你不能使用
     <code>
 get_id()
 </code>
     方法就可以了。
  
  
    但是，代码中的主要问题首先来自结帐帐单字段。应按如下设置，显示和保存它们
    
      （特别照顾
       <code>
 meta_keys
 </code>
       在保存数据时使用）
    
    ：
  
   <pre>
 <code>
 // Frontend: Display the custom billing fields (in checkout and my account)
add_filter( 'woocommerce_billing_fields' ,'add_custom_billing_fields', 20, 1 );
function add_custom_billing_fields( $fields ) {

$fields['billing_address_3'] = array(
        'label' => __( 'Home', 'woocommerce' ),
        'placeholder'   => _x('Fill in your Home', 'placeholder', 'woocommerce'),
        'required'  => true,
        'class'     => array('form-row-wide'),
        'clear'     => true
    );

$fields['billing_address_4'] = array(
        'label' => __( 'Entrance', 'woocommerce' ),
        'placeholder'   => _x('Fill in your Entrance', 'placeholder', 'woocommerce'),
        'required'  => true,
        'class'     => array('form-row-wide'),
        'clear'     => true
    );

$fields['billing_address_5'] = array(
        'label' => __( 'Floor', 'woocommerce' ),
        'placeholder'   => _x('Fill in your Floor', 'placeholder', 'woocommerce'),
        'required'  => true,
        'class'     => array('form-row-wide'),
        'clear'     => true
    );

return $fields;
}

// Save the custom billing fields (once order is placed)
add_action( 'woocommerce_checkout_create_order', 'save_custom_billingt_fields', 20, 2 );
function save_custom_billingt_fields( $order, $data ) {
    if ( isset( $_POST['billing_address_3'] ) && ! empty( $_POST['billing_address_3'] ) ) {
        $order->update_meta_data('_billing_address_3', sanitize_text_field( $_POST['billing_address_3'] ) );
        update_user_meta( $order->get_customer_id(), 'billing_address_3', sanitize_text_field( $_POST['billing_address_3'] ) );
    }
    if ( isset( $_POST['billing_address_4'] ) && ! empty( $_POST['billing_address_4'] ) ) {
        $order->update_meta_data('_billing_address_4', sanitize_text_field( $_POST['billing_address_4'] ) );
        update_user_meta( $order->get_customer_id(), 'billing_address_4', sanitize_text_field( $_POST['billing_address_4'] ) );
    }
    if ( isset( $_POST['billing_address_5'] ) && ! empty( $_POST['billing_address_5'] ) ) {
        $order->update_meta_data('_billing_address_5', sanitize_text_field( $_POST['billing_address_5'] ) );
        update_user_meta( $order->get_customer_id(), 'billing_address_5', sanitize_text_field( $_POST['billing_address_5'] ) );
    }
}

      您会看到这些自定义字段也在我的帐户中＆gt;地址＆gt;修改帐单邮寄地址相关的一切都是自动同步。无需额外验证或保存代码......

    现在在管理员订单页面中，用于
     <code>
 woocommerce_admin_billing_fields
 </code>
     管理员钩，
     <code>
 'value'
 </code>
     字段数组中不存在键
    的
      这是有罪的
    </强>
    。
  
  
    由于您已正确设置和保存自定义结帐字段，因此您不需要任何其他字段
     <code>
 'value'
 </code>
     数组键，因为数据将是
    的
      自动填充
    </强>
    ，如果它存在。所以你的代码将是：
  
   <pre>
 <code>
 // Backend: Display editable custom billing fields
add_filter( 'woocommerce_admin_billing_fields' , 'order_admin_custom_fields' );
function order_admin_custom_fields( $fields ) {
 global $the_order;

$fields['address_3'] = array(
        'label' => __( 'Home', 'woocommerce' ),
        'show'  => true,
        'wrapper_class' => 'form-field-wide',
        'style' => '',
    );

$fields['address_4'] = array(
        'label' => __( 'Entrance', 'woocommerce' ),
        'show'  => true,
        'wrapper_class' => 'form-field-wide',
        'style' => '',
    );

$fields['address_5'] = array(
        'label' => __( 'Floor', 'woocommerce' ),
        'show'  => true,
        'wrapper_class' => 'form-field-wide',
        'style' => '',
    );

return $fields;
}

 </pre>
  
    代码位于活动子主题（或活动主题）的function.php文件中。经过测试和工作。
