Uploaded file no extention about php-file-upload-class HOT 2 CLOSED

I have same problem, i can't download file after upload becouse there isn't extension

from php-file-upload-class.

When file is saved on disk - it's saved without extension.

If you want to preserve extension then you need to extend this class and modify way how filename is generated.

https://github.com/aivis/PHP-file-upload-class/blob/master/upload.php#L578

class MyUploadClass extends Upload 
{
//....
    /**
     * Set unique filename
     * 
     * @return string
     */
    protected function create_new_filename() {

        $filename = 'xss-safe-filename-with-extension.png';
        $this->set_filename($filename);

    }

But keep in mind that if you will leave extensions like ".php" and if the file permissions will not be correct - then there will be very dangerous vulnerability!
