Hello,
I want to add a custom form field “Attach image” on the checkout page at the top or bottom of the page which will be sent to the vendor with the order details.
[Attach Image] button to open Finder on desktop and file manager or camera on mobile.
Do you have GenerateBlocks plugin installed? If so, you can use a buttonsblock with dynamic data enabled to achieve this. https://www.screencast.com/t/XCJ0DoBdU
