How to upload multiple files to Google Drive from WordPress page

I’m rather new to WordPress development. I need to add a web form to one of my WordPress pages which will allow a user (using BuddyPress) to upload multiple files to a Google Drive folder.

On a submission I would like the files in that submission to all be added together in a folder titled by the date followed by the username like this: yyMMddhhmmss_username.

Any idea how I can accomplish this?
