How do i rename the file to be stored ? about upload

[yahyaerturan]

You can use sanitizer callback as renamer. I am doing like this:

function upload_renamer($raw_file_name)
{
    $fileName = pathinfo($raw_file_name, PATHINFO_FILENAME);
    $fileExt  = pathinfo($raw_file_name, PATHINFO_EXTENSION);
    return slug($fileName).'.'.slug($fileExt);
};

$uploadHandler->setSanitizerCallback('upload_renamer');

Surely you can call anything in the callback function.
