title: Woocommerce Admin Order Page Required Fields
body: <p>I use the Admin Order Page of WooCommerce to book certain products in a box office.</p>
  
  <p>I want to make certain customer data required fields. (Like first_name,last_name,email etc.)</p>
  
  <p>That the order can only be processed (saved) with this data entered in the billing information field.</p>
  
  <p>I haven't found any solution on the internet that makes the fields in the admin panel required. Only found solutions for the frontend.</p>
  
  <p>Any ideas? </p>
