Re: How I can receive itemid for creating file?

I've uploaded my code to github https://github.com/spnova/groupreg

"This block allow you add assign students to groups by csv file"

I need store files for excel report, with process description.

https://github.com/spnova/groupreg/blob/master/process.php [line 56]

Downloading excel with report:

>the Files API covers everything you should be doing with files

But I can't find API for getting free itemid for new file store.
