Probably simple but I have a custom field that I would like to add to the Orders channel and then use that value in the customer notification email.
This field will not be populated by the customer, it's a custom date field that the admin has set for a course.
In the add to cart form I have:
<input type="hidden" name="date_booked_for" value="{course_date}" />
where the date_booked_for is the new field in the Orders Channel and course_date is the custom field that needs to be passed to checkout and then the email.
Stuck on the hidden field part in the checkout form and email notification.
Any ideas please?
TIA
