Change quantity via jQuery and disabile quantity field [closed]

If the input is disabled, it is ignored during form submission. You can try to use readonly attribute.

As it says in the docs: The difference between disabled and readonly is that read-only controls can still function and are still focusable, whereas disabled controls can not receive focus and are not submitted with the form and generally do not function as controls until they are enabled.
