title: WooCommerce: How to hide prices in customer-on-hold-order Mail, but not in other Mails?
body: <p>I need to customize WooCommerce and hide all Pricing Information in the customer-on-hold-order Mail, but not in the other Mails.</p>
  
  <p>I have already copied Mail Templates to /mytheme/woocommerce/emails earlier, and because they are already modified, i copied </p>
  
  <p>email-order-items.php and
  email-order-details.php </p>
  
  <p>to </p>
  
  <p>email-order-items-noprice.php and
  email-order-details-noprice.php</p>
  
  <p>...and modified them to show no price.</p>
  
  <p>Now I believe I must change customer-on-hold-order.php to call my new noprice files</p>
  
  <p>In this file I can see</p>
  
  <pre><code>do_action( 'woocommerce_email_order_details', $order, $sent_to_admin, $plain_text, $email );
  </code></pre>
  
  <p>I wish that I could just change the line to</p>
  
  <pre><code>do_action( 'woocommerce_email_order_details_noprice', $order, $sent_to_admin, $plain_text, $email );
  </code></pre>
  
  <p>...but then nothing happens. It is probably because the hook 'woocommerce_email_order_details_noprice' does not exist.</p>
  
  <p>What must I do to create this hook, and where?
  Or is there a better solution to this?</p>
  
  <p>Thanks a lot!</p>
