Adding Custom Fields To Emails

To use this code, follow these steps:

  1. Add this snippet to your theme’s functions.php file
  2. Change the meta key names in the snippet
  3. Create a custom field in the order post — e.g. key = “Tracking Code” value = abcdefg
  4. When next updating the status, or during any other event which emails the user, they will see this field in their email
add_filter(‘woocommerce_email_order_meta_keys’, ‘my_custom_order_meta_keys’);
function my_custom_order_meta_keys( $keys ) {
 $keys[] = ‘Tracking Code’; // This will look for a custom field called ‘Tracking Code’ and add it to emails
 return $keys;
