I need to add more fields to my checkout page versus the standard ones that are already programmed in. The theme I am using is ShowTime. Is there a way for me to do this?
If you are literally talking about the checkout (and not cart) be aware that access to the checkout template is limited to Shopify Plus merchants.
You can do that on the cart page, not the checkout page. Adding info like that is done with cart attributes. Are the links above not helpful?
Also have the same challenge where the customer is required to capture certain information when purchasing a particular product only. For example they need to capture their Identity numbers when purchasing mobile phones. I also need to extract a report of the data.
What would be the best way to execute this.
