Editing code on Customer order confirmation to include Calender dates

Current Issue:

  • Order confirmations display standard shipping dates (24 hours after order placement)
  • Rental booking dates and times selected by customers are not appearing in confirmation emails

Desired Outcome:

  • Remove shipping dates from rental orders
  • Display customer-selected rental dates and times directly under the product name (e.g., “Roof Box & Roof Bar Hire”)

Hello Shopify Community,

I’m looking for assistance with custom coding for my customers email confirmations.

I use a shopify app called Izyrent for booking in rentals and currently the selected dates and times for bookings do not show on order confirmations, only shipping dates (usually 24hrs after the order was placed, which I need removing from these specific orders containing hire bookings and replacing with their chosen dates and times for hire).

Can anybody help?

So for example on the confirmation page I’d like it to show the selected dates and times underneath the product item, this one being “Roof Box & Roof Bar Hire”
