Try prefixing your UNC path with two forward slashes:
$targer_dir = "//192.168.232.199/xampp/htdoc/training/uploads/image/images/".$nama.".jpeg";
NB: You will need to validate the
$nama
variable to ensure that it doesn't contain any invalid file-name characters. Otherwise, an attacher could overwrite files in an unexpected directory by including ".." in the
no_pengajuan_full_day
field.
