WooCommerce 自定义字段 PHP 7 工作 PHP 7.1 和 7.2 不工作

Question

我正在向我的 Woocommerce 帐单和送货地址添加一个“标题”字段。一切都适用于 PHP 7，但是当我升级到 7.1 或 7.2 时，WooCommerce 中的订单页面会崩溃并且无法正确显示订单。所以即使有 3 页订单，我也只能看到第一个订单，如果我点击那个订单，它只会显示部分详细信息，根本没有地址。

非常感谢任何想法。

此问题可能来自第一个挂钩函数，其中$order->billing_title; 不正确，因为从 Woocommerce 3 开始，大多数对象属性都无法直接访问。 $order WC_Order Object 实例就是这种情况。相反，您可以使用继承的WC_Data 方法get_meta()。

钩子优先级和参数也有一些错误。

尝试以下重新访问的代码：

// Add Title field in billing address display
add_filter( 'woocommerce_order_formatted_billing_address', 'custom_add_title_formatted_billing_address', 10, 2 );
function custom_add_title_formatted_billing_address( $billing_address, $order ) {
    $billing_address['title'] = $order->get_meta( '_billing_title');
    return $billing_address;
}

add_filter( 'woocommerce_my_account_my_address_formatted_address', 'custom_my_account_my_address_formatted_address', 10, 3 );
function custom_my_account_my_address_formatted_address( $address, $customer_id, $address_type ) {
    if ( $address_type == 'billing' ) {
        $address['title'] = get_user_meta( $customer_id, 'billing_title', true );
    }
    return $address;
}

add_filter( 'woocommerce_address_to_edit', 'custom_address_to_edit', 10, 2 );
function custom_address_to_edit( $address, $load_address ) {
    global $wp_query;
    if ( isset( $wp_query->query_vars['edit-address'] ) && $wp_query->query_vars['edit-address'] != 'billing' ) {
        return $address;
    }
    if ( ! isset( $address['billing_title'] ) ) {
        $address['billing_title'] = array(
            'label'       => __( 'Title', 'your-domain' ),
            'placeholder' => _x( 'Mr', 'placeholder', 'your-domain' ),
            'required'    => false, //change to false if you do not need this field to be required
            'class'       => array( 'form-row-first' ),
            'value'       => get_user_meta( get_current_user_id(), 'billing_title', true )
        );
    }
    return $address;
}

add_filter( 'woocommerce_formatted_address_replacements', 'custom_formatted_address_replacements', 10, 2 );
function custom_formatted_address_replacements( $replacements, $args  ) {
    $replacements['{title}'] = '';
    if ( ! empty( $args['title'] ) ) {
        $replacements['{title}'] = __( 'Title', 'your-domain' ) . ' ' . $args['title'];
    }
    return $replacements;
}

add_filter( 'woocommerce_localisation_address_formats', 'custom_localisation_address_format', 10, 1 );
function custom_localisation_address_format( $formats ) {
    $formats['IT'] .= "\n\n{title}";
    return $formats;
}

add_filter( 'woocommerce_admin_billing_fields', 'custom_admin_billing_fields', 10, 1 );
function custom_admin_billing_fields( $billing_fields ) {
    $billing_fields['title'] = array(
        'label' => __( 'Title', 'your-domain' ),
        'show'  => true
    );
    return $billing_fields;
}

add_filter( 'woocommerce_found_customer_details', 'custom_found_customer_details', 10, 1 );
function custom_found_customer_details( $customer_data ) {
    $customer_data['billing_title'] = get_user_meta( $_POST['user_id'], 'billing_title', true );
    return $customer_data;
}

add_filter( 'woocommerce_customer_meta_fields', 'custom_customer_meta_fields', 10, 1 );
function custom_customer_meta_fields( $show_fields ) {
    $show_fields['billing']['fields']['billing_title']['label'] = __( 'Title', 'woocommerce' );
    return $show_fields;
}

我没有看到任何其他可能在 PHP 7.2 中造成问题的东西……
