Codeigniter - Need help uploading picture to both folder and database - php

Question

I need help uploading the picture to the folder and database. It seems I can only send it to the database, but not upload it to the folder. Is there anything wrong with the code?
admin.php (controller)
public function input_siswa(){
$config['upload_path'] = './gambarfolder/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload');
$this->upload->initialize($config);
$location=base_url().'/gambarfolder/';
$pict=$location.$data_imge;
$nama_siswa = $this->input->post('nama_siswa');
$nis = $this->input->post('nis');
$id_jurusan = $this->input->post('id_jurusan');
$data = array(
'nama_siswa'=>$nama_siswa,
'nis'=>$nis,
'id_jurusan'=>$id_jurusan,
'gambar'=>$pict
);
$this->m_model->create('siswa',$data);
redirect(base_url('index.php/admin/tampil_siswa'));
}

Upload image in codeigniter using upload library.
public function input_siswa(){
$config['upload_path'] = './gambarfolder/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$location=base_url().'/gambarfolder/';
$pict=$location.$data_imge;
$this->load->library('upload', $config);
if ($this->upload->do_upload('userfile'))
{
$nama_siswa = $this->input->post('nama_siswa');
$nis = $this->input->post('nis');
$id_jurusan = $this->input->post('id_jurusan');
$data = array(
'nama_siswa'=>$nama_siswa,
'nis'=>$nis,
'id_jurusan'=>$id_jurusan,
'gambar'=>$pict
);
$this->m_model->create('siswa',$data);
redirect(base_url('index.php/admin/tampil_siswa'));
// redirect succsess page when image upload succsessfully.
}else{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload', $error);
// return image upload error.
}
}

first check your folder gambarfolder is in the root of your codigniter application
second check in your form tag you add enctype="multipart/form-data"
and add that lines for upload image to gambarfolder folder
$this->load->library('upload', $config);
if($this->upload->do_upload('userfile'))
{
}
where userfile is the name of file tag like
<input type="file" name="userfile" size="20" />
and $config is your config array
and also check https://www.codeigniter.com/userguide3/libraries/file_uploading.html

You need to add below line after initialise config
$this->upload->do_upload('userfile')
