Cart and checkout validation using js, but can I validate checkout using PHP?
I looked at the documentation but could not figure it out.

The image has added validation in js according to the documentation.
I would like to do this in PHP.

Hi Tera3,

Currently Shopify Functions don't support PHP so you'll need to work with either JavaScript, TypeScript, Rust, or Wasm.

Thank you. By the way, is it possible to validate the cart using anything other than Shopify Functions?
We are looking to develop a feature that will only allow members to purchase member-only products.
