After few days, since I asked this question: LINK I realized, that maybe it's another problem.
I used package
inotifywait to check, is a temporary file generating after sending html form. Unfortunately temp file is not creating, after clicking "upload" button in my form, but I don't know why, because even I had turned off firewall (I thought that it is a problem - I was wrong). Maybe someone has this same problem?
OS is newly installed, so I didn't change so much in
Below is a list 'What I checked?':
- File size is in limit, which is set into
upload_max_filesize(limit is 2MB, but file have 18KB),
- I tried to use aboslute path,
/var/www/html/uploadhave chmod set on 777 and
uploadowner and owner group is apache,
- I tried change
php.ini, but it bring this same result.
