File attachment

HI

I set file upload field in product page as required. How can I change required to non-required when user select a checkbox on product page?

P.S I have one more question. In which  variable is stored information that a file is uploaded.

it requires core changes,

fact that file is required and whole engine to check if there are files is a part of prestashop core, so it is necessary to alter the core.

whole modification depends on how and what checkbox you added, this checkbox must be stored somewhere (information if it is selected or not)

only then it will be possible to build feature like this.
