Question

i want to upload files with multiple input. I have tried the code below, but the files not uploaded, and i cant get the upload directory.
HTML
<input type="file" name="userfile[]" size="20" />
Controller
public function detailTugasInput($idKelas,$id){
$this->load->model('tugass');
$records = $_FILES['userfile'];
//var_dump($records); die();
$config['upload_path'] = './file/';
$config['allowed_types'] = 'pdf|doc|txt|jpg|png';
$config['max_size'] = 0;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
foreach ($_FILES as $key => $value) {
$upload_data = $this->upload->data();
$file_ary = array(
'nama_kembali' => $value['name'],
'file_kembali' => $value['tmp_name']
);
}
}
