我创建了两个插件：
我已经成功地在注册表单，结帐页面和用户仪表板面板中添加了我的字段，但在结帐页面上我无法用预先设定的值填充它们。
第一个插件用于在注册时添加新字段。新字段为：'billing_bulstat'; 'billing_mol'和'billing_adres'。它们已成功保存并显示在用户仪表板面板中。代码是：

第二个插件在结帐页面上添加了三个新的自定义字段。它们会显示，但不会自动填充。我使用$ checkout-＆gt; get_value（'my_field_name'））;功能，但是不起作用。
我想让它们自动填充预先设定的值。字段相同：'billing_bulstat'; 'billing_mol'和'billing_adres'。代码是：
