Hello!
Sorry for my English.
The task is:
Registered users cannot download zip archives from the Lightbox. Zip archives can download only one group, which I will build.
That is, if the registered user clicks on the zip, then pops up the inscription, "in order to be able to download a zip archive, you need to obtain improved access to the site. For clarification please contact the site administrator"
The not as it turns out I do. PHP only began to study
