如何自动更新插件
要接收自动更新，只需安装并配置 Envato 更新程序插件： https://goo.gl/pkJS33 .说明如何配置它的官方指南可以在以下链接中找到：https://envato.com/market-plugin .
理念
WCEV 扩展了 WooCommerce，添加了一个欧盟增值税号字段，该字段将在结帐过程中动态显示，并且仅当所选账单国家/地区是欧盟的一部分时，才会添加用户个人资料页面（账单地址）。Shop Admin 也可以将其设为强制性和选择性
验证它（插件使用 视觉障碍 函数，或者只是检查它是否具有有效的格式）。它还允许您不向输入 Vat 号的用户收费。
配置
通过访问 WooCommerce -> 欧盟增值税字段 – 选项 您可以配置 Plugin 选项。例如，您可以禁用必填 选项或显示需要发票 客户的声音
可以请求发票。此外，启用此选项后，您还可以使该字段仅在用户请求发票时可见。
增值税验证
增值税号可以使用 视觉障碍 功能。如果验证失败，插件将不允许完成结帐，并且
将显示验证警告消息（可使用文本 菜单）。
也可以通过检查增值税号是否具有有效格式来执行验证。
不要用无用的签出字段来打扰您的用户！
为什么要要求您的客户 公司名称 和增值税 如果他们只是消费者？WCEV 让您不打扰他们！
使用以下选项：
- 索取发票：仅在用户请求发票时显示 Vat 字段。
- 消费者/企业选择器 以动态显示公司名称 和增值税 字段。
免税
WCEV 插件还允许您不对插入增值税号的用户收取增值税。免税可以应用于具有增值税号的所有用户（甚至可以选择适用于与商店基地位置具有相同账单国家/地区的用户：WooCommerce -> 设置 -> 常规 -> 基地位置）。
税费减免将影响 Shop、Product、Cart 和 Checkout 页面。在“结账”中输入有效的增值税号后，将显示“我的账户 – >账单地址”或“注册”页面、商品价格和总计，并无税计费。
如果您选择显示 Vat 字段，即使对于非欧盟用户，您最终还可以启用选项，以便为输入增值税号的非欧盟用户删除税费。但请注意， 无验证 将对这些增值税号执行。
企业对企业 （B2B） 变得简单！
商店管理员还可以根据需要设置 Billing company name 字段！因此，可以选择将此选项与 VIES 增值税验证方法和启用的“税务删除”选项结合使用，商店管理员可以轻松地进行企业对企业 （b2b） 销售。
新增功能： 新的注册页面 – 只有企业可以注册 选项现在将只允许有效的企业在您的商店中注册！输入的增值税税号将根据所选的验证选项和所选的账单国家/地区进行验证
如果无效，用户将无法注册！
增值税号唯一性检查
（可选）该插件可以执行唯一性检查，以避免不同的用户使用相同的增值税号。
意大利特殊领域
如果选择意大利作为账单国家/地区，则将显示 Codice fiscale 和 SDI/Pec 字段。它还将对其格式执行验证。
西班牙特殊字段
如果选择西班牙作为账单国家/地区，则将显示 NIF / NIE /CIF 字段。它还将对其格式执行验证。
希腊特殊领域
如果选择西班牙作为账单国家/地区，则在选择企业类型时，将显示“税务局”和“企业活动”字段。
标签和文本（WPML 可本地化）
字段标签、占位符和验证错误消息可以使用 发短信 菜单。为WMPL 用户，只需使用 WPML 语言选择器切换当前语言，然后输入当前语言的文本，即可对文本进行本地化。
前端集成
WCEV 将欧盟增值税字段无缝集成到 Checkout （结帐）、My Account （我的账户） 和 Order （订单） 详细信息页面以及 Order （订单） 电子邮件中。无需配置！
后端集成
WCEV 在后端无缝集成了欧盟增值税字段。商店管理员可以检索增值税号信息，如果用户请求了发票，则可以从 订单详细信息 和 订单 列表页面检索增值税号信息：
支持意大利 “Fatturazione Elettronica”
在意大利国家/地区选择的情况下，插件还会显示 SDI/Pec 字段，允许客户输入其 SDI 代码/Pec 地址。商店管理员可以自定义显示的标签、描述和验证消息！
验证说明： 该插件将仅检查电子邮件的格式是否正确，或者 SDI 代码是否为 7 个字符长的字母数字代码。
您是WooCommerce PDF发票和装箱单的用户吗？
如果您使用的是 WooCommerce PDF发票和装箱单由wp隔夜提供 插件生成发票，并且你想报告用户与订单关联的增值税号，只需修改你正在使用的模板（通常是 templates/Simple/invoice.php）
并使用以下代码段：
< ?php global $wcev_order_model; $vat_number = $wcev_order_model->get_vat_number($order_id); ? >
检索增值税号。$order_id 变量是要检索字段的订单的 ID。要显示它，只需使用以下代码段
echo $vat_number;
您是WooCommerce打印发票和装箱单的用户吗？
如果您使用的是 WooCommerce由SkyVerge打印发票和装箱单 插件生成发票，并且您想报告与订单关联的用户增值税号，只需修改要显示它的模板部分（模板位于：templates/pip）
并使用以下代码段：
< ?php global $wcev_order_model; $vat_number = $wcev_order_model->get_vat_number($this->order_number()); ? >
检索增值税号。$order_id 是您要检索字段的订单的 ID。
例如，如果要在 User details （用户详细信息） 中显示它，请编辑 templates/pip/content/order-table-after.php 文件。在第 98 行，您将找到一个名为 Customer Details 的部分。在 ul 中（第 91 行之后），您可以添加如下内容：
< ?php global $wcev_order_model; $vat_number = $wcev_order_model->get_vat_number($this->order_number()); ? > <li class=""><?php echo '<strong>Vat Number</strong> '. $vat_number ; ?></li>
自定义结帐表单通知
该插件旨在与默认结帐表单和结帐页面模板 （[woocommerce_checkout]） 一起使用。使用任何插件、使用自定义结账模板（例如，某些主题可能正在实施多步骤结账）或自定义外观（外观 -> 自定义 -> WooCommerce）添加或删除字段都可能导致插件无法正常工作。
