Answer 1

it looks like there are some typos in your code
try this instead
function tambah($gambar,$pdf){
$kd_mastersub = $this->input->post('kd_mastersub');
$nama = $this->input->post('nama');
$picture = $gambar['nm_gbr'];
$deskripsi = $this->input->post('deskripsi');
$pdf = $pdf['nm_pdf'];
$video = $gambar['nm_video'];
$drive = $gambar['nm_drive'];
$data = array(
'kd_mastersub' =>$kd_mastersub,
'name_cate' =>$nama,
'picture' => $picture,
'description' =>$deskripsi,
'pdf' => $pdf,
'video' => $video,
'drive' => $drive
);
$this->db->insert('tbl_mastersub',$data);
}
