How to upload file codeigniter to database

Question

I have tried but it always appears error unable to load the upload class.

 function save()
 {

    $id_pemesanan=$this->input->post('id_pemesanan');
    $nama_pemesan=$this->input->post('nama_pemesan');
    $email=$this->input->post('email');
    $jumlah=$this->input->post('jumlah');
    $tgl_bayar=$this->input->post('tgl_bayar');
    $metode_pembayaran=$this->input->post('metode_pembayaran');

    $data['id_pemesanan'] = $id_pemesanan;
    $data['nama_pemesan'] = $nama_pemesan;
    $data['email'] = $email;    
    $data['jumlah'] = $jumlah;
    $data['tgl_bayar'] = $tgl_bayar;
    $data['metode_pembayaran'] = $metode_pembayaran;

    $this->db->trans_start();

    $this->db->insert('konfirmasi', $data);

    $this->db->trans_complete();  



    if ($this->db->trans_status() === FALSE)
            {
                $this->session->set_flashdata("msg", "<div class='alert bg-danger' role='alert'>
                <a href='#' class='close' data-dismiss='alert' aria-label='close'>&times;</a>
                <svg class='glyph stroked empty-message'><use xlink:href='#stroked-empty-message'></use></svg> Data gagal tersimpan.
                </div>");
                redirect('konfirmasi/konfirmasi_list'); 
            } else 
            {
                $this->session->set_flashdata("msg", "<div class='alert bg-success' role='alert'>
                <a href='#' class='close' data-dismiss='alert' aria-label='close'>&times;</a>
                <svg class='glyph stroked empty-message'><use xlink:href='#stroked-empty-message'></use></svg> Data  tersimpan.
                </div>");
                redirect('konfirmasi/konfirmasi_list'); 
            }

 }

this is my model

public function datakonfirmasi()
{
$query = $this->db->query('SELECT * FROM konfirmasi');
return $query->result();
}

and this is my views

<div class="row">
  <ol class="breadcrumb">
    <li><a href="#"><svg class="glyph stroked home"><use xlink:href="#stroked-home"></use></svg></a></li>
    <li class="active">konfirmasi</li>

How to upload image files?

Answer 1

Saving files in database isn't a good practice. You should save file to some folder with some name and store only path to this file in DB. Whenever you need this file you just get it from your filesystem - because you know path to this file

Answer 2

save the files in a folder with in your application folder in code-igniter in htdocs and save the path in database. that would be a good practic.

Answer 3

try this:

in your controller

function save(){
//add yourmodel
$this->load->model('Yourmodels');

$id_pemesanan=$this->input->post('id_pemesanan');
$nama_pemesan=$this->input->post('nama_pemesan');
$email=$this->input->post('email');
$jumlah=$this->input->post('jumlah');
$tgl_bayar=$this->input->post('tgl_bayar');
$metode_pembayaran=$this->input->post('metode_pembayaran');
$this->db->trans_start();

change

$this->db->insert('konfirmasi', $data);

to:

// call function insert_pemesanan on yourmodels
$this->Yourmodels->insert_pemesanan($data);


$this->db->trans_complete();

in Yourmodels add function insert_pemesanan

function insert_pemesanan($value = []){
$this->db->insert('konfirmasi',$value);
}
