Detailed Description

Provides file management functions.

You can upload, store, list and manage files.

• Files are stored in directory structure 'rootdir/year/month/' by default.
• Each file has record in database table FILESTORAGE and it is assigned to some entity (specified by location $loc).
• Examples: $fs->setFiles(['products', 1], $fs->postedFiles()); //Save posted files $fs->getFiles(['products', 1]); //return array with list of files for product_id=1 $fs->getFile(123); //return file with id=123
